Modelling Alkali Line Absorption and Molecular Bands in Cool DAZs
Derek Homeier, Nicole F. Allard, France Allard +4
Two peculiar stars showing an apparent extremely broadened and strong NaI D absorption have been discovered in surveys for cool white dwarfs by Oppenheimer et al. (2001) and Harris…
Double degenerates and progenitors of supernovae type Ia
R. Napiwotzki, L. Yungelson, G. Nelemans +12
We report on systematic radial velocity surveys for white dwarf - white dwarf binaries (double degenerates - DDs) including SPY (ESO Supernovae Ia progenitor survey) recently carri…
Methane and the Spectra of T Dwarfs
Derek Homeier, Peter H. Hauschildt, France Allard
We have updated our PHOENIX model atmospheres and theoretical spectra for ultracool dwarfs with new opacity data for methane based on line strength predictions with the STDS softwa…
Methane Opacities in T Dwarf Atmospheres
D. Homeier, P. H. Hauschildt, F. Allard
We present the current status of PHOENIX model atmospheres for dwarfs of the spectral type T, typical for older field brown dwarfs and low-mass brown dwarfs. The results are based…
