  Weighing Ultra-Cool Stars
This system - with the telephone number name of 2MASSW J0746425+2000321 [3]- is located at a distance of 40 light-years.
During their four-year long study, seven different relative positions of the two components of the binary system were measured and Hervé Bouy and his co-workers were able to determine with good precision the stellar orbits.
Using the latest stellar models of the group of the Ecole Normale Supérieure de Lyon, they found that both stars have roughly the same surface temperature, around 1500 °C (1800 K).

 SOLAR SYSTEMS formation process
In the Milky Way galaxy, the nucleus expulses outwards, by explosions or blow outs, quantities of stellar matter in the form of stellar clusters or group of stars, which incorporate to the galaxy as a stellar group and begin orbiting the galactic nucleus which originate them, sometimes integrating the bands which conform the galactic structure.
In this way, the system establishes in its first order which is an orbitational arrangement where the allocation, position and role of the stellar masses is initially defined.
The dynamics and structure of stellar systems is quite similar to that of solar systems.

 Star system at AllExperts
A star system or stellar system is a system comprised of a star or group of stars, and, perhaps, planetary systems of smaller bodies (such as planets or asteroids), in gravitational association.
Systems with more than two starsare also possible; for example, a star cluster or galaxy is a kind of star system.
Theoretically, modelling a multiple star system is more difficult than modelling a binary star, as the dynamical system involved, the n-body problem,may exhibit chaotic behavior.Many configurations of small groups of stars are found to be unstable, as eventually onestar will approach another closely and be accelerated so much that it will escape fromthe system.

 [No title]
Stellar system planets (planemos orbiting fusors) are additionally classified as major/minor based on a test of dynamical dominance or "clearing the neighborhood." The macro/micro and major/minor dimensions are taken as orthogonal.
A _microplanet_ is a microplanemo orbiting a fusor and not the satellite of another non-fusor: that is, a stellar system planet with insufficient mass to attain a near-spherical or globose shape constrained by self-gravity.
The Earth-Moon system in a scenario where it is permitted to evolve (undisturbed by changes associated with solar aging, or other cosmic vicissitudes) to the point where its barycenter moves outside's Earth radius, or even at present in a "quasi-dual planet" perspective, presents a possible example of a binary major planet system.

 Stellar Evolution and Death -- Glossary
The star may be a white dwarf, a neutron star, or a stellar fl hole in a close stellar binary system.
White dwarfs are the burned-out stellar remnants of formerly normal stars of modest mass (less than eight solar masses) that have exhausted their nuclear fuel.
Such systems consist of a neutron star or fl hole that accretes matter from a nearby, mass-losing stellar companion.

 Space Studies Board
Existence of a planetary system around one or more of the components of a multiple stellar system is not necessarily precluded, although the planetary orbital distances must either be very small or very large compared with the separation of the stars.
The energetic stellar winds and bipolar outflows (jetlike collimated flows) observed during the ~105 to 106 yr of the ensuing contraction phase are now widely believed to occur simultaneously with infall of material from the protostellar cloud to the circumstellar disk and inflow of material to the central mass through the disk.
In the inner solar system both the heating and tidal effects of the Sun, as well as the smaller amount of condensable material, apparently prevented the buildup of cores to the critical mass where significant gas accretion was possible.

 At The Earth's Core
The most important aspect of the stellar evolutionary system that we are considering is the death of a star—the supernova.
The second supernova byproduct--the imploded stellar core--forms a white dwarf star, with all of its unusual characteristics: inverse density gradient, intense magnetic field, quantized emission, and all the phenomenon associated with intermediate-speed (2-x) motion.
The outer region of the inner core is basically the "stellar interior" of a white dwarf, having an inverse density gradient.

 The Evolution of Solar Systems
The final stage is typical of a well aged stellar system in which most of the smaller debris is cleaned up and only large planets exist well separated from each other in dissonant orbits around the central star.
The smaller the system is, the slower is its evolution.
These systems are found in well separated binary stars, where planet sized bodies accrete in the Lagrangian points in the secondary stars orbit around the primary higher mass star.

 ChrisW's Thoughts on Advanced Stellar Conquest
A system with habitability 2 and 4 TFs present, for example, requires a total of 6 new Colony Expeditions to create the fifth TF, yet that fifth TF produces the same number of credits per turn as the first.
Systems with a habitability rating of less than 1 would be treated as having a habitability rating of 1 until the total number of colonies was equal to the absolute value of the habitability rating.
This system could be used, either by placing these chits on the board at the beginning, or by conducting an exploration roll whenever a system is first explored.

 A family portrait of the Alpha Centauri System
The two main stars in the system, Alpha Centauri A and Alpha Centauri B, are rather similar to the Sun; their stellar spectral types are "G2V" and "K1V", respectively.
In addition to providing general information about stellar evolution, the detailed study of Alpha Centauri A and B is particular interesting as it allows verification of our current knowledge about the composition, structure and indeed, future development, of our own main energy source, the Sun.
During the past years, a number of more distant binary stellar systems like Alpha Centauri A and B have been observed with different methods, including spectrophotometry (emission at different wavelengths) and astrometry (position in the sky; motions).

 ESO - 2000
An evaluation of the new data by an international team of astronomers [1] shows that it is by far the youngest of only four such objects found in a stellar system so far.
If the companion candidate and the brighter star belong to the same stellar system, they must move together on the sky or, as astronomers say, their measured "proper motions" must be (nearly) the same.
This greatly strengthens the conclusion that they are physically connected in the same multiple stellar system.

 Baby star cluster seen at Universe's edge - 05 October 2001 - New Scientist
Astronomers have spotted a star system in the infant stages of formation that could reveal much about the early evolution of the Universe.
The lensing effect makes the star system at least 30 times brighter than would be the case if the galaxy cluster were not in the foreground.
The Universe is estimated to be about 14 billion years old, yet the astronomers estimate they are seeing this stellar system less than one billion years after the big bang.

 Fields for each star system
In very rare instances, a star may be "quarternary" (two binary stars orbiting each other), "quinary" (a trinary star system where two of the three "stars" are actually close-orbiting binaries) or even "hexary" (a trinary star system where all three "stars" are close-orbiting binaries).
In some rare cases, such as Castor, the A, B, etc., components of a star system may themselves be close binary star pairs, in which case they are referred to as A1 and A2, then B1 and B2 — or Aa and Ab, then Ba and Bb, depending on what the discoverer preferred.
Bear in mind that any planets in a multiple star system must be closer to the star they are orbiting than 25% of the Periastron distance between that star and its nearest neighbor; otherwise, their orbits wouldn't be stable and they'd fly off into deep space.

 Sky Publishing - The Stellar Magnitude System   (Site not responding. Last check: )
The faintest stars he could see he called "of the sixth magnitude." This system was copied by Claudius Ptolemy in his own list of stars around A.D. Sometimes Ptolemy added the words "greater" or "smaller" to distinguish between stars within a magnitude class.
Several photometric systems have been devised; the most familiar is called UBV after the three filters most commonly used.
So successful was the UBV system that it was extended redward with R and I filters to define standard red and near-infrared magnitudes.

 Scientists Track Collision of Powerful Stellar Winds
The supersharp radio "vision" of the continent-wide VLBA allowed the scientists to measure the motion of the wind collision region and then to determine the details of the stars' orbits and an accurate distance to the system.
The astronomers tracked the system for a year and a half, noting dramatic changes in the wind collision region.
The scientists watched the changes in the stellar system as the star's orbits carried them in paths that bring them nearly as close to each other as Mars is to the Sun and as far as Neptune is from the Sun.

 Spaceflight Now | Breaking News | X-ray emission measured from jets of infant stars
This young stellar system - in fact consisting of two stars - is less than a million years old.
At the same time, a stellar wind evacuates matter, creating a kind of cavity around the jets which reflects the light from the two stars.
In most cases of young stellar objects, the X-ray luminous stars are visible and therefore outshine any jets which the objects may produce.
