Topic: Vega (planet)


  
 Vega (Alpha Lyrae)
In 1983, based on observations by the Infrared Astronomy Satellite (IRAS), Vega became one of the first stars to be discovered with a large luminous infrared-radiating halo that suggests a circumstellar cloud of warm dust.
Since Vega seems to be rotating with its pole directed toward Earth, the dust cloud probably represents a face-on disk that may not be unlike the disk surrounding the Sun and that contains the planets.
Instead, calculations show that an eccentric planet traps dust in two main concentrations at different distances from the star, at positions outside the planet orbit that are generally not in line with the star.

 Vega
Vega was the first star to be photographed, exposed for 100 seconds with the daguerreotype process through a 15-inch refractor at Harvard Observatory on the night of July 16-17, 1850.
Vega is a Delta Scuti type of pulsating variable star (over 0.1903 days) whose slight variations have been a matter of debate since their detection in 1918 by Paul Guthnick (1879-1947) and Richard Prager (1883-1945) (Vasil'yev et al, 1989).
Their best explanation for the presence of the second disk is that an unseen planet with as much as 20 times the mass of Jupiter in an orbit within the secondary disk is gravitationally sweeping up dust and icy planetesimals from the primary disk (more from hubblesite.org).

 Vega - Crystalinks
Vega is the brightest star in Lyra, and the fifth brightest star in the sky.
Therefore the visual magnitude of Vega was decided to be, by definition, zero at all wavelengths for many years (this is no longer the case, as the apparent magnitude zero point is now most commonly defined in terms of a particular numerically specified flux).
The flux density of Vega drops rapidly in the infrared, and is near 100 Jy at 5 micrometres.

 Venus - Picture - MSN Encarta
Swirling clouds of sulfur and sulfuric acid obscure Venus’s surface and inhibited study of the planet from Earth until technology permitted space vehicles, outfitted with probes, to visit it.
These probes determined that Venus is the hottest of the planets, with a surface temperature of about 460° C (about 860° F).
Scientists believe that a greenhouse effect causes the extreme temperature, hypothesizing that the planet’s thick clouds and dense atmosphere trap energy from the sun.

 Manual:Planet types - VsWiki
University planets have populations ranging from about three hundred thousand to two billion, although occasionally the designation is also used for planets with much lower populations on which the only habitation is a single large university or research facility.
Oceanic planets are lifebearing, although biodiversity may be reduced by the homogeneity of the environment (except for those planets with reefs or reef-analogues.) Many oceanic planets are the results of terraforming efforts and as such have a terran biota.
Overgrown planets are a subset of bio-diverse planets in which the planet is judged to be uninhabitable or undesirable based on the indigenous life forms.

Vega, located 25 light years away in the constellation Lyra, is the brightest star in the summer sky.
The new observations of Vega's dust cloud were made at a wavelength of 1.3 millimeters with the Plateau de Bure Interferometer (PdBI) of the Institut de RadioAstronomie Millimetrique (IRAM), an array of five 15-meter (49-foot) diameter antennas located in the French Alps.
Instead, calculations by the astronomers show that an eccentric planet traps dust in two main concentrations at different distances from the star, at positions outside the planet orbit that are generally not in line with the star.

 Joint Astronomy Centre - Astronomers discover possible new Solar Systems in formation around the nearby stars Vega and ...   (Site not responding. Last check: 2007-10-11)
Vega, in the constellation of Lyra (the Lyre) and the brightest star in our summer sky, is the oldest star of the three at 350 million years old.
While the blobs in the Vega and Beta Pictoris images may be dust-enshrouded giant planets, planets are not supposed to be able to form at such great distances from stars, the researchers noted.
Noting that none of the stars has retained a large enough mass of dust to form planets, the astronomers say that if these stars are orbited by planets, they have most likely already formed, or are well on their way to forming.

 Harvard Gazette: Dusty trails may reveal new planet
Jupiter, the largest planet in the solar system, sweeps out a pattern of dust that would be visible from Vega with the same type of telescopes available on Earth.
The tug of gravity from these planets produces slight wobbles in the paths of their suns, which can be detected by changes in their light.
From this perspective, the planet seems to be in an elliptical orbit that takes it almost 3 billion miles from Vega, or about the distance from the sun to Neptune.

Venus is a very dry planet, but water vapor plays a critical role in the chemistry of its atmosphere, being necessary for the formation of the cloud aerosol of sulpuric and phosphoric acid.
A carrier wave from the main Vega spacecraft was simultaneously recorded, allowing a very precise measurement of the relative distance between the two transmitters.
During the night-time portion of the journey, considerable variations in light levels were detected by the photometer, possibly due to thin spots in the lower cloud layer, revealing the thermal glow of the planet's surface.

 Detecting Hidden Planets by Analyzing Circumstellar Disks
According to a team of NASA and university researchers, the gravitational influence of newborn planets weaves patterns in the dust disk from which they were formed, and the type of pattern depends on the planet's mass and orbital characteristics.
For example, a common planet detection method is to use the wobble produced in a star's motion by the gravitational pull of unseen massive planets orbiting it.

Although she cautions that astronomers haven't proved that the features they see have been sculpted by planets, theorists are using the newest data to refine estimates of the mass of proposed planets, their distance from their parent stars, and the shapes and tilts of their orbits.
A lurking planet, she proposes, could generate such an abundance of small grains by generating collisions between rocky bodies in the neighborhood.
The clumps in Vega's disk could be signs that a planet with a highly elongated path resides at a distance from its parent similar to that of the solar system's outer planets, Holman and his colleagues suggest in the April 20 Astrophysical Journal Letters.

The Vega 5VK spacecraft was designed for a mission combining a flyby of the planet Venus followed by an encounter with Halley's Comet.
In 1981, it was decided to cancel the 5VS orbiters and redesign the 5VP to expand the Halley research programme (this may have been in response to the cancellation of the US Halley probe the same year).
The Vega 5VK spacecraft were fitted with scientific apparatus and equipment built in the USSR, Austria, Bulgaria, Hungary, German Democratic Republic, Poland, France, Federal Republic of Germany and Czechoslovakia.
