Which Are The Brightest Gravitational Wave Sources In Our Galaxy?
LISA is a space-based mission to detect gravitational waves. What will be the brightest targets it can see?
A Pebbly Barrier to Planet Formation
While a planet is forming, its passage through the protoplanetary disk can prevent pebbles from migrating inwards and accreting onto the planet.
For Whom the Cosmic Web Tolls
“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 (Non?)-Magnetic White Dwarf Binary
A white dwarf binary system that sometimes shows evidence of a magnetic field — but only some of the time.
Protoplanetary Disks might be More Turbulent
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.
A Helium-Powered Supernova
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.
