Red giant masses and ages derived from carbon and nitrogen abundances
Marie Martig, Morgan Fouesneau, Hans-Walter Rix +7
We show that the masses of red giant stars can be well predicted from their photospheric carbon and nitrogen abundances, in conjunction with their spectroscopic stellar labels log…
How to bend galaxy disc profiles II: stars surfing the bar in Type-III discs
Jakob Herpich, Gregory S. Stinson, Hans-Walter Rix +2
The radial profiles of stars in disc galaxies are observed to be either purely exponential (Type-I), truncated (Type-II) or anti-truncated (Type-III) exponentials. Controlled forma…
Creating S0s with major mergers: a 3D view
Miguel Querejeta, M. Carmen Eliche-Moral, Trinidad Tapia +8
A number of simulators have argued that major mergers can sometimes preserve discs (e.g. Springel & Hernquist 2005), but the possibility that they could explain the emergence of le…
Formation of S0 galaxies through mergers: Explaining angular momentum and concentration change from spirals to S0s
Miguel Querejeta, M. Carmen Eliche-Moral, Trinidad Tapia +6
The CALIFA team has recently found that the stellar angular momentum and concentration of late-type spiral galaxies are incompatible with those of lenticular galaxies (S0s), conclu…
Young [/Fe]-enhanced stars discovered by CoRoT and APOGEE: What is their origin?
C. Chiappini, F. Anders, T. S. Rodrigues +34
We report the discovery of a group of apparently young CoRoT red-giant stars exhibiting enhanced [alpha/Fe] abundance ratios (as determined from APOGEE spectra) with respect to Sol…
How to bend galaxy disc profiles: the role of halo spin
Jakob Herpich, Gregory S. Stinson, Aaron A. Dutton +6
The radial density profiles of stellar galaxy discs can be well approximated as an exponential. Compared to this canonical form, however, the profiles in the majority of disc galax…
