Could Companion Stars Cause Stripped-Envelope Supernovae?
How do you make a supernova without hydrogen and helium lines? The answer may surprise you! (It’s probably binary stars)
The Case of the Missing Black Hole
A rare triple system consisting of two stars and a black hole was thought to be in our cosmic backyard. Can new observations from the ESO make the black hole vanish into thin air?
(Mis)alignment Between Exoplanets and Binary Stars
Binary star systems host exoplanets too! But are planetary orbits aligned or misaligned relative to the stellar companion?
Giraffes exist, and Unicorns too!
What do giraffes and unicorns have in common with red giant binary systems? Find out in today’s bite!
A home has secrets too…
We don’t talk about accretion disks enough, but they hide so much physics in them! The authors of today’s paper try to understand which physical effect wins in circumbinary disks!
The Last Message of Devoured Planets
Traces of planets devoured by their host stars can possibly be found within the external layers of the stellar surface. These remains tell a story of the evolution and architecture of different planetary systems and grant new appreciation for our relatively calm environment.
