Today’s paper discusses a recent, unusual supernova, which may be the first strong evidence for a long-predicted phenomenon: an exploding white dwarf triggered by an initial explosion in its atmosphere.
When it comes to habitability for Earth-like life, we’ve got more than just liquid water to worry about. Today’s astrobite looks at how planets could lose portions of their atmospheres to quasar radiation.
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?
Astronomers have found hydrogen contamination in the atmospheres of helium white dwarfs – but where in the world/universe is it coming from?! The authors of today’s astrobite perform statistical tests to see if the source of this pesky hydrogen could be water-bearing rocky bodies out in space.
A star that spins fast enough to throw off its atmosphere, and a hint at how it got that way.
Five young stars in one system — all the same age but at different stages of their evolution. What can they tell us?
