Astronomers have discovered an RR Lyrae variable star inside an open cluster for the first time! But this oddball star just might end up challenging our understanding of how RR Lyraes evolve.
What are blue straggler stars and how are they formed? By using spectroscopy, today’s authors explain the link between this question and how fast these objects spin!
Keeping track of millions of stars is tricky. Today’s authors take on the challenge of accounting for each one’s time of birth.
Thick stellar winds might be blowing away the chances of forming intermediate-mass black holes from the collapse of very massive stars.
Some supernovae have bumpy light curves – could a baby neutron star repeatedly diving into the envelope of its inflated companion be the cause? Today’s authors simulate this to find out!
How does theory overpredict the number of black holes we see? And what can we do about it? Find out in today’s bite!
