description Overview

WR 140

WR 140 is a variable star system located in the constellation Cygnus, consisting of a massive Wolf-Rayet star and a hot O-type giant companion. These two stars follow a highly eccentric 7.9-year orbit, coming close enough together to generate colliding stellar winds that shock the surrounding gas. This interaction produces periodic shells of heated plasma and dust that expand outward into space. I...

Sirius B

Sirius B is a dense white dwarf star orbiting within the Sirius system of Canis Major. It represents the remnant core of a once-massive star that exhausted its nuclear fuel. This object’s extreme density—a sun's mass packed into Earth-sized volume—makes it a valuable subject for astronomical research and provides insights into stellar evolution. Astronomers study Sirius B to understand white dwarf...
