Judging a book by its cover: estimating red supergiant masses from their surface abundance
Can astronomers use core-collapse supernova to find out the mass of their progenitors? Find out in today’s bite!

I attempt to summarize what some astronomers have called “undoubtedly the most brilliant Ph.D. thesis ever written in astronomy.”
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.
In today’s guest post, Caitlin Doughty discusses how carbon lines are misidentified and their impact on cosmology.
In this article, the authors measure the stellar mass-metallicity relation for star forming galaxies ranging to z~2.3. They find that mass-metallicity relationship for these galaxies evolves with time and also that it flattens at late times.
This paper describes a new diagnostic that separates galaxies from AGN at much higher redshifts than the traditional BPT diagram.
