Reference Star
Alpha PsA (24 PsA; Fomalhaut, "the fish's mouth"; HD 216956; SAO 191524)
Position: 2258-2937
Mag : 1.17
Spectrum : A3 V
Color : W!
Assumed distance: 25 light years
Assumed luminosity (suns): 16.3
Notes:
The diameter of Fomalhaut is about 0.0020".
This star is an infra-red source.
From James Kaler's Star Notes:
Usually pronounced "fo-ma-low," the name means the "fish's mouth," and comes
from a longer Arabic phrase meaning "the mouth of the southern fish."
It at first seems like yet another ordinary white "class A" star similar to, though a bit
cooler than, Vega in Lyra (which passes nearly overhead in temperate latitudes) with a
surface temperature of about 8,500 Kelvin. Almost the same distance as Vega, it is over a
full magnitude fainter to the eye as a result of somewhat lower mass, which results in a
lower surface temperature and smaller size.
In 1983 an orbiting satellite called IRAS discovered far more infrared radiation
coming from the star than expected. Infrared is a signature of a cool source. The radiation
is coming from a huge disk of matter four times the dimension of our planetary system
that surrounds the star much like those that encompass Vega and Denebola. The disk is
thought to be made of icy dust particles that have been warmed by the star. The planets of
our Solar System almost certainly formed from the accumulation of dust in just such a
disk. Recent observations of Fomalhaut's disk shows a hole in the middle. Could the hole
be the result of planets that have removed the dust? So far none have been detected.
