the dieing stars have a larger ratio than the just born stars.
According to <studyisland.com>, white dwarfs are the oldest.
Giant Dwarves are old stars.
There are all kinds of stars in our Milky Way galaxy. Our sun is a G2V type star. There are red giants, blue giants, white dwarfs, red dwarfs, brown dwarfs, and probably even black dwarfs (burned out suns), neutron stars, and pulsars. There are also herbig-haro objects, a peculiar type of star that emits collimated bipolar jets of radiation.
About 10% are yellow dwarfs.

Both white dwarfs and neutron stars are extremely dense remnants of the collapsed cores of dead stars.
White dwarfs are the remnants of dead low to medium mass stars, which is the mass range of the majority of stars.
The very smallest "stars" in the galaxy are brown dwarfs. These are starlike objects that have failed to produce sustained nuclear fusion.
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.
The most common stars are Red Dwarfs. It is probable that up to 80% of all stars in the universe are red dwarfs. They are not visible on the on the H-R Diagram because they are hard to observe from Earth due to their low-luminosity. In contrast O-type and B-type supergiants are extremely rare. The reason for this is because they evolve and die quickly.
