Example of massive main sequence star
WebSep 26, 2024 · The basic definition of a 'giant' star is one that is more luminous than a main sequence star. As the name suggests, part of the reason for this is simply that such stars are enormous in size. WebSep 26, 2024 · Sirus, the brightest star in the night sky, is a binary star consisting of Sirius B, a massive white dwarf and Sirius A, an A-type main sequence star. (Image credit: …
