Fundamental Parameters and Abundances of Metal-Poor Stars: The SDSS Standard BD +17 4708
I. Ramirez, C. Allende Prieto, S. Redfield +1
The atmospheric parameters and iron abundance of the Sloan Digital Sky Survey (SDSS) spectrophotometric standard star BD +17 4708 are critically examined using up-to-date Kurucz mo…
Carbon stars in local group dwarf galaxies: C and O abundances
R. Wahlin, K. Eriksson, B. Gustafsson +4
We present abundances of carbon and oxygen as well as abundance ratios 12C/13C for a sample of carbon stars in the LMC, SMC, Carina, Sculptor and Fornax dwarf galaxies. The overall…
R Coronae Borealis at the 2003 Light Minimum
N. Kameswara Rao, David L. Lambert, Matthew D. Shetrone
High-resolution optical spectra of R CrB obtained in 2003 March is discussed. The 2003 spectra are compared with the extensive collection of spectra from the 1995-1996 minimum. Spe…
Water vapor on supergiants. The 12 micron TEXES spectra of mu Cephei
N. Ryde, M. J. Richter, G. M. Harper +2
Several recent papers have argued for warm, semi-detached, molecular layers surrounding red giant and supergiant stars, a concept known as a MOLsphere. Spectroscopic and interferom…
