Mu Normaeとは 意味・読み方・使い方

Mu Normae is a blue supergiant star in the constellation Norma. Though it has an apparent magnitude of only 4.914, its absolute visual magnitude -5.86 and a bolometric luminosity of 210,000 times that of the Sun. This star is comparable to Epsilon Orionis (Alnilam) in that they are both of class B0 and are supergiants, but this star is less massive at a probable mass of 30 solar masses. Both stars are also suspected of being Alpha Cygni variables which are named after the also similar star Deneb. Being a blue supergiant, it is destined to become a red supergiant in a few million years and eventually a type-II supernova.
