“No [galaxy] is an island entire of itself; every [galaxy] / is a piece of the [cosmic web], a part of the main” – apologies to John Donne for butchering his poem.
A white dwarf binary system that sometimes shows evidence of a magnetic field — but only some of the time.
Turbulence plays a key role in determining what types of planets can form in a disk. We are finally on the verge of measuring this property for the first time using CO spectral lines, but it will only work if we factor in how quickly CO can be depleted.
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?
