Betelgeuse companion discovery with Gemini North resolves century-old mystery and opens new doors in red supergiant research ...

But all of that extra attention has led to another remarkable find. As it turns out, Betegeuse isn’t alone—it actually has a nearby companion star. The never-before-seen celestial object is detailed ...

The Sun is very much a main sequence star, in the G-type category (G2V to be precise). It’s been fusing hydrogen for 4.6 billion years, but it still has almost three times as much as it has helium.

Astronomers have uncovered a new mystery surrounding a pinwheel-shaped star system—while, fortunately, revealing it is not likely to live up to its "death star" reputation. Located approximately ...

The First Catalog of Candidate White Dwarf–Main-sequence Binaries in Open Star Clusters: A New Window into Common Envelope Evolution. The Astrophysical Journal, 2024; 976 (1): 102 DOI: 10.3847 ...

That prompted three astrophysicists (Isabelle John, Rebecca Leane, and Tim Linden) to try to look at things in an organized fashion, modeling a "dark main sequence" of stars as they might exist ...

Thuban, named in Ancient Egypt and meaning “ head of the serpent ”, consists of a white giant star 2.8 times as massive as the Sun, with a secondary star thought to be an A-type main-sequence ...

LHS 1140 b orbits around a low-density M-type main sequence star, otherwise known as a red dwarf, that’s roughly one-fifth the size of our Sun. Discovered some 48 light-years away from Earth in ...
