A peculiar X-ray binary may contain the first known white dwarf which is still in the process of contracting.
When it zips past the Galactic Center black hole in 2018, how would a possible binarity of the star S0-2 affect the detectability of its relativistic motion?
In Be/X-ray binaries — systems in which a Be star spins so fast that it throws its own matter away towards its neutron star companion — it’s possible for accretion discs to form that spin backwards. What does this mean for the stars?
A star that spins fast enough to throw off its atmosphere, and a hint at how it got that way.
Planetary nebulae where they shouldn’t be–how did they get there?
Today we look at a polluted white dwarf in a binary system: by calculating how many sperm whales accrete onto the white dwarf each second, can we say anything about planet formation?
