Bellatrix is a giant. In general most stars with "names" (as opposed to designations) are NOT dwarfs, with a few notable exceptions such as Proxima.
White Dwarf, Sun, Red Giant, Supernova
A giant star is a dying star that expanded, and the core shrinks are the same time. When the shell of the giant star drift into space as planetary nebula, the core became a white dwarf. The white dwarf is made from the core of the giant star.
The correct order is red giant followed by white dwarf. A red giant is a stage in the life cycle of a star where it has expanded and cooled. After the red giant phase, the star sheds its outer layers and the core collapses to form a white dwarf.
Gamma Orionis (Bellatrix), is the third brightest star in the constellation Orion.Bellatrix has a spectral type of B2 and is a blue-white giant.See related link for a pictorial. (Bellatrix is the blue-white giant, whereas the small yellow one is the Sun)
Gamma Orionis (Bellatrix) is the third brightest star in the constellation Orion.It is about 5.7 times larger than our SunSee related link for a pictorial comparison. (Bellatrix is the blue star, and the Sun is in the centre)
A giant star would experience a supernova explosion, in order to become a white dwarf.
A dwarf star is denser than a giant star. Dwarf stars have a higher density due to their smaller size and higher mass compared to giant stars. Giant stars have larger volumes and lower densities as they have expanded and become less dense towards the end of their life cycle.
