I thought I might try using Celestia to have a look at the Pistol Star from a hypothetical Pluto in orbit around it
(not that such a planet would have time to form);
from here
http://www.tim-thompson.com/bright-stars.html
I got the visual absolute magnitude (high estimate) as -10.4
and the bolometric absolute magnitude as -13.3;
making a model of the star using the bolometric figure first (which includes UV) I got a temperature for Hypothetical Pistol/Pluto of 5500K;
then making a model of the star using the visual absolute magnitude I got the apparent brightness as magnitude-34.53, much brighter than the Sun as seen from Earth...
I don't know how reliable these figures are, as the Celestia simulator does all the calculations itself; but it looks good; the closest stellar type in this program is class O so that is what I described it as.
The diameter of the Pistol star is said to be about 2AU so Celestia has got that about right; how accurate is the simulator at these excessive values I wonder?
