Topic: Alpha Canis Minoris


  
  Procyon 2
Alpha Canis Minoris A has a close companion star B that is separated "on average" by only about 16 times the distance from the Earth to the Sun -- 14.9 astronomical units (AUs) of an orbital semi-major axis -- which is roughly the distance between Uranus and our Sun.
Alpha Minoris B, the companion star, is a white dwarf, stellar remnant and is so dim that it cannot be perceived with the naked eye.
Alpha Canis Minoris A, the Little Dog Star, is the eighth brightest star in the night sky as well as the brightest star in its constellation.

 Procyon (Alpha Canis Minoris)
The brightest star in the constellation Canis Minor, the eighth brightest star in the sky, and the easternmost star of the Winter Triangle.
Its Greek name means “before the dog,” since in northern latitudes it rises before Sirius, the Dog Star, and its constellation, Canis Major.
Procyon is a nearby yellow-white subgiant F star, about to shut down the fusion of hydrogen to helium in its core.

 Finding the Constellations from Southern Africa
Canis Minor, the Little Dog constellation, is a small "two-star" figure near Canis Major, the Greater Dog.
Canis Minor is not too difficult to find due to its alpha star, Procyon, being the 8th brighest star visible from the Earth.
As you become accustomed to its position, Canis Minor will quickly appear in the darker region of sky it lies in, becoming a landmark constellation for your navigation of the night sky.

 Alpha Canis Minoris System
Although the gravitational pull of α Canis Minoris B significantly reduces the distance at which a planet orbiting Procyon can have a stable orbit, there is still a small zone where a planet would have a stable orbit and not get too much light from Procyon.
However, the system is so young (1.7 Ga) that any life would be extremely primitive: Terra at this point still only had single-celled life and the atmosphere was still a reducing atmosphere with methane and ammonia taking up the portion taken up by molecular oxygen now.
Any planet orbiting the right distance to not be cooked or frozen would be so close that α Canis Minoris B's gravity would tidally lock it, it would orbit with one side always facing the star.

Although first detected in the 1960s by photography, sigma-Hydrids are typically swift and faint, and rates generally low, often close to the visual detection limit.
Since their radiant, just to the southwest of the "head" asterism of Hydra, a little over 10° east of Procyon (alpha Canis Minoris), is near the equator, all observers can cover this shower, whose peak this year is only a day after new Moon.
alpha, delta, alpha, delta: Coordinates for a shower's radiant position, usually at maximum; alpha is right ascension, and delta is declination.

 Star Names
Note that more than one popular name may be applied to some stars: for example, Alpha Andromedae is known as Alpheratz and Sirrah, both derived from Arabic.
The Millennium Star Atlas and the second edition of of Sky Atlas 2000.0 were both based on the Hipparcos catalogue and hence were obliged to follow that catalogue’s choice of names.
However, someone at Sky Publishing, publisher of both atlases, quietly changed the name “Kocab” for Beta Ursae Minoris to the previously used “Kochab”, so there is now an inconsistency between catalogue and charts.

 Astronomy of the Brazilian Flag
This language is not in the 1889 decree but was added much later, at a time when I believe the Brazilian Congress would have written 20:30 if it meant 20:30.
Astronomical: The point of specifying the time is that the constellation of the Southern Cross (Crux australis, Cruzeiro do sul) was at the meridian of Rio with Gamma crucis and Alpha crucis aligned vertically.
This is what the flag shows and, according to astronomers, occurred at either 08:30 or 08:37 (in the morning).

Schmitt, Drake, Stern and Haisch have determined the coronal density of the nearby star alpha Canis Minoris (CMi), using ratios from detected iron spectral lines of different ionization stages (ranging from FeIX to FeXIV).
This implies that the corona of alpha CMi is, presumably, structured in a similar manner as to that of the Sun and, furthermore, the coronal filling factor is estimated to be about 20%.
Drake, Laming and Widing have analyzed spectral lines due to the elements Ne, S, Ar, Fe, and Si in the EUVE spectrum of the alpha Centaurus AB system.
