Calibrating M dwarf metallicities using molecular indices
Vincent M Woolf, George Wallerstein
We report progress in the calibration of a method to determine cool dwarf star metallicities using molecular band strength indices. The molecular band index to metallicity relation…
The MultiSite Spectroscopic Telescope campaign: 2m spectroscopy of the V361 Hya variable PG1605+072
S. J. O'Toole, U. Heber, C. S. Jeffery +10
We present results and analysis for the 2m spectroscopic part of the MultiSite Spectroscopic Telescope (MSST) campaign undertaken in May/June 2002. The goal of the project was to o…
Metallicity measurements using atomic lines in M and K dwarf stars
Vincent M. Woolf, George Wallerstein
We report the first survey of chemical abundances in M and K dwarf stars using atomic absorption lines in high resolution spectra. We have measured Fe and Ti abundances in 35 M and…
The Rise of the s-Process in the Galaxy
J. Simmerer, C. Sneden, J. J. Cowan +3
From newly-obtained high-resolution, high signal-to-noise ratio spectra the abundances of the elements La and Eu have been determined over the stellar metallicity range -3<[Fe/H]<+…
Temperature and gravity of the pulsating extreme helium star LSS 3184 (BX Cir) through its pulsation cycle
Vincent M. Woolf, C. Simon Jeffery
We report the analysis of optical spectra of the extreme helium star LSS 3184 (BX Cir) to determine its effective temperature and gravity throughout its pulsation cycle. The spectr…
Radial velocity variations of the pulsating subdwarf B star PG 1605+072
Vincent M. Woolf, C. Simon Jeffery, Donald L. Pollacco
We present an analysis of high-speed spectroscopy of the pulsating subdwarf B star PG 1605+072. Periodic radial motions are detected at frequencies similar to those reported for ph…
