White Dwarf Star Measurements Bring Milky Way Into Focus
Understanding the masses of stars in the early stages of their lives, before they became white dwarfs is key to understanding the formation of galaxies. New research by astronomer, Jason Kalirai, has described a new technique for calculating this through the use of the mass of the white dwarf stars they become.
The age of a star is directly related to its mass. The more massive a star, the more pressure at its core and the faster it burns through its hydrogen supply. This is key. The increasing precision with which we can calculate age and mass helps us resolve the entire sequence of stellar evolution.
