Web8 okt. 2024 · Aldebaran is shedding mass at a rate of (1–1.6) × 10 −11 M ⊙ yr −1, or one Earth mass every 300,000 years, through a stellar wind.. It is classified as a slow irregular variable (LB) star. Its brightness varies from magnitude 0.75 to 0.95 according to historical records given in the General Catalogue of Variable Stars (GCVS). WebThe answer turns out to be about 2.5, which is the fifth root of 100. This means that a magnitude 1.0 star and a magnitude 2.0 star differ in brightness by a factor of about 2.5. Likewise, we receive about 2.5 times as much light from a magnitude 2.0 star as from a magnitude 3.0 star.
