Starburst dwarfs - fueling and morphological evolution

Nils Bergvall, Goran Ostlin, Josefa Masegosa +1

The effects of mergers in low mass galaxies are poorly understood. In this paper we analyze different observational evidences which support the view that mergers can trigger starbu…

The r-Process Enriched Low Metallicity Giant HD 115444

Jenny Westin, Christopher Sneden, Bengt Gustafsson +1

New high resolution, very high signal-to-noise spectra of ultra-metal-poor (UMP) giant stars HD 115444 and HD 122563 have been gathered with the High-Resolution Echelle Spectromete…

Optical properties of carbon grains: Influence on dynamical models of AGB stars

Anja C. Andersen, Rita Loidl, Susanne Hofner

For amorphous carbon several laboratory extinction data are available, which show quite a wide range of differences due to the structural complexity of this material. We have calcu…

A Consistency Test of Spectroscopic Gravities for Late-Type Stars

Carlos Allende Prieto, Ramon J. Garcia Lopez, David L. Lambert +1

Chemical analyses of late-type stars are usually carried out following the classical recipe: LTE line formation and homogeneous, plane-parallel, flux-constant, and LTE model atmosp…

Spectroscopic Observations of Convective Patterns in the Atmospheres of Metal-Poor Stars

Carlos Allende Prieto, Ramon J. Garcia Lopez, David L. Lambert +1

Convective line asymmetries in the optical spectrum of two metal-poor stars, Gmb1830 and HD140283, are compared to those observed for solar metallicity stars. The line bisectors of…

The carbon star IRAS 15194-5115: Circumstellar CO radio and FIR rotational lines

N. Ryde, F. L. Schoeier, H. Olofsson

We have modelled radio and far-infrared rotational lines of 12^CO and 13^CO obtained from the circumstellar envelope of the infrared-bright carbon star IRAS 15194-5115. Eleven rota…
