"Prospecting in Ultracool Dwarfs: Measuring the Metallicities of Mid- and Late-M Dwarfs," by Mann, et al. http://arxiv.org/abs/1403.5560v1

Apr 08, 2014 12:30 pm - Paul Canton

The first introduces some semirecent observations of R Coronae Boreallis, the prototype of a class of luminous variables:  'The Circumstellar Environment of R Coronae Borealis: White Dwarf Merger or Final-helium-shell Flash?'

http://adsabs.harvard.edu/abs/2011ApJ...743...44C

The second is a popular paper which addresses the question of where these stars may come from, and how they fit in the grand picture of stellar evolution: 'Very Large Excesses of 18O in Hydrogen-deficient Carbon and R Coronae Borealis Stars: Evidence for White Dwarf Mergers'

For my half of journal club on Tuesday, I'll be discussing my ALMA/EVLA/IRAM work on the Kleinmann-Low star-forming nebula, from my summer at NRAO, which I presented at AAS. I'll keep it self-contained, but if anyone's very eager to get a head start, a relevant reference that significantly overlaps with our work might be: Neill et al. 2013, http://adsabs.harvard.edu/abs/2013ApJ...777...85N
