Noclip on! Simulated primordial black holes could dance through Sun-like stars
What might the orbit of a primordial black hole going in and out of a Sun-like star look like?
These stars are never ever getting back together!
Happy Red’s release week, swifties! Today we discuss a paper about RED giants, and how you can tell if they had undergone a merger or not!
A Star Askew: A Potential Cause of the Misalignment of a Star and Its Planets
When the rotation of a star is misaligned from the orbits of its planets, astronomers often attribute the misalignment to planetary dynamics. In the case of K2-290 A, today’s authors instead attribute its misalignment to its stellar companion.
A supercomputer made of idle CPUs rewinds stellar streams
Astronomers connect volunteered computers on MilkyWay@home and model the dark matter content of dwarf galaxies.
Finding fire-breathing dragons in the Milky Way
Dark matter subhalos are invisible and hard to detect, but astronomers in today’s paper use stellar streams to take a stab.
The Nobel Prize in Physics 2020: Reinhard Genzel
This week we’re celebrating this year’s astronomical awardees for the Nobel Prize in Physics. Today we have Reinhard Genzel and his pioneering work on constraining the black hole at the centre of our Galaxy
