The Fates of Planets Orbiting White Dwarfs
This article considers the fate of planets that orbit stars that will become white dwarfs. Can they survive? Could they be habitable?
Tidal tails of dwarf galaxies on different orbits around the Milky Way
A phenomenological series of simulations of dwarf galaxies placed on different orbits around a Milky Way-like galaxy, in order to learn about the properties (and observability) of tidal tails in dwarf galaxies around our Milky Way.
The Top 12 of 2012
What were astronomers reading and talking about in their research last year? Check out figures from the top 12 most-cited astronomy papers from 2012 (so far) and find out what researchers were up to and why!
Exploding diamonds in the sky
Pakmor et al. propose a new mechanism to make Type 1a supernova explosions from a pair of white dwarfs.
Asteroid Excavation: Probing the interior of Vesta through major impacts
The asteroid Vesta has been scared by two giant impacts, dredging up material from deep below its surface. New simulations of the impacts allow us to trace where the material should end up and creates a conflict between theory and observation.
Mapping star formation in galaxies using slitless spectroscopy
A team of astronomers working on the 3D-HST survey make use of the Hubble Space Telescope’s grism to observe star formation as a function of radius in a large sample of galaxies at intermediate redshift.
