What can binary stars comprised of two different types of stars teach astronomers about stellar evolution? This is what a recent study published in The Astrophysical Journal hopes to address as a team ...

Technically, the sun is a G-type main-sequence star — specifically, a G2V star. The "V" indicates that it is a dwarf, Tony Wong, a professor of astronomy at the University of Illinois Urbana-Champaign ...

Astronomers have discovered the first pairs of white dwarf and main sequence stars -- 'dead' remnants and 'living' stars -- in young star clusters. This breakthrough offers new insights on an extreme ...

For a star, its initial mass is everything. It determines how quickly it burns through its hydrogen and how it will evolve once it starts fusing heavier elements. It’s so well understood that ...

Stellar size and class diversification originates from the initial mass of the molecular cloud from which stars form. The elemental composition of the molecular cloud, specifically the abundance of ...
