Taking its place is a new model of vascular biology, epigenomics, and nutragenomicsâhow foods (and supplements) influence heart health.
delta Cephei. The namesake star in the very important class of stars known as Cepheid variables, this star formed part of the original study in which Henrietta Leavitt first discovered that the periods of luminosity were related to their absolute luminosity.This has proved to be an important distance measuring tool.amed after delta-Cephei, Cepheid Variables are the most important type of variable because it has been discovered that their periods of variability are related to their absolute luminosity.
Well, not exactly. There are many different types of stars, from the tiny brown dwarfs to the red and blue supergiants. There are even more bizarre kinds of stars, like neutron stars and Wolf-Rayet stars. Letâs take a look at all the different types of stars there are.Red giant Betelgeuse.ed Dwarf Star.

They have another advantage.
