Helium-burning white dwarf:
Using #ESA_XMM and #eROSITA #spacetelescope, a team lead by #MPE researchers discovered a #binarystar🌟🌟, where material flows onto a #WhiteDwarf, but instead of #hydrogen, the material is #helium, making it the first helium-burning white dwarf ever discovered!

This is awesome.
This scifi writer has created a sundial for a hypothetical planet in a binary star system. Top notch worldbuilding.

We report the detection of a gas-giant #planet in orbit around both stars of an eclipsing #binarystar system that also contains a smaller, inner transiting planet . The new planet was discovered using radial-velocity data , it is a 65.2 M⊕ #circumbinary planet with a period of 215.5 days. This is the first detection of a circumbinary planet using radial-velocity observations alone, and makes it only the second confirmed multiplanet circumbinary system to date: https://arxiv.org/abs/2301.10794
