Bellatrix
(Constellation Orion)
(Constellation Orion)
I chose this star because I think it might actually be the name of a character in one of the Harry Potter movies, so I thought it would be funny to analyze this star.
Since 1963, Bellatrix was included with a set of bright stars that astronomers employ as a luminosity standard. These are used for comparison with other stars to check for variability, and so by definition, the apparent magnitude of Bellatrix was set to 1.64. However, when an all-sky photometry survey was carried out in 1988, this star was itself found to be variable. It ranges in apparent magnitude from 1.59 to 1.64.
