Grain Physics and Rosseland Mean Opacities
Jason W. Ferguson, Amanda S. Heffner-Wong, Jonathan J. Penley +2
Tables of mean opacities are often used to compute the transfer of radiation in a variety of astrophysical simulations from stellar evolution models to proto-planetary disks. Often…
Low Temperature Opacities
Jason W. Ferguson, David R. Alexander, France Allard +5
Previous computations of low temperature Rosseland and Planck mean opacities from Alexander & Ferguson (1994) are updated and expanded. The new computations include a more complete…
The YY Isochrones for alpha-element Enhanced Mixtures
Yong -Cheol Kim, Pierre Demarque, Sukyoung K. Yi +1
We present a new set of isochrones in which the effect of the alpha-element enhancement is fully incorporated. These isochrones are an extension of the already published set of YY…
The Limiting Effects of Dust in Brown Dwarf Model Atmospheres
France Allard, Peter H. Hauschildt, David R. Alexander +2
We present opacity sampling model atmospheres, synthetic spectra and colors for brown dwarfs and very low mass stars in two limiting case of dust grain formation: 1) inefficient gr…
The NextGen Model Atmosphere grid: II. Spherically symmetric model atmospheres for giant stars with effective temperatures between 3000 and 6800~K
Peter H. Hauschildt, France Allard, Jason Ferguson +2
We present the extension of our NextGen model atmosphere grid to the regime of giant stars. The input physics of the models presented here is nearly identical to the NextGen dwarf…
NLTE effects of Ti~I in M dwarfs and giants
Peter H. Hauschildt, France Allard, David R. Alexander +1
We present detailed NLTE Ti~I calculations in model atmospheres of cool dwarf and giant stars. A fully self-consistent NLTE treatment for a Ti~I model atom with 395 levels and 5279…
