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 ...

When it comes to science, a simple observation can upend everything you think you know, such is the case with one star ...

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 ...

New X-ray observations reveal Betelgeuse’s mysterious companion is not a collapsed stellar remnant but a young, Sun-like ...

Binary star systems are not rare. Neither are systems where one star is a remnant like a white dwarf or neutron star, and its companion is on the main sequence. In those systems, the dense remnant can ...

Dark matter particle and antiparticle collisions could make some stars immortal. I am still seeing recent studies on this topic—certainly ones newer than 7 years ago, when the article linked was ...
