Theoretical light curves of type Ia supernovae
D. Jack, P. H. Hauschildt, E. Baron
Aims. We present the first theoretical SN Ia light curves calculated with the time-dependent version of the general purpose model atmosphere code PHOENIX. Our goal is to produce li…
Comparing Numerical Methods for Isothermal Magnetized Supersonic Turbulence
Alexei G. Kritsuk, Aake Nordlund, David Collins +13
We employ simulations of supersonic super-Alfvenic turbulence decay as a benchmark test problem to assess and compare the performance of nine astrophysical MHD methods actively use…
Comoving-frame radiative transfer in arbitrary velocity fields -- II. Large scale applications
S. Knop, P. H. Hauschildt, E. Baron
A solution of the radiative-transfer problem in arbitrary velocity fields introduced in a previous paper, has limitations in its applicability. For large-scale applications, the me…
Optical and Near-Infrared Spectroscopy of the L Subdwarf SDSS J125637.13-022452.4
Adam J. Burgasser, Soeren Witte, Christiane Helling +3
Red optical and near-infrared spectroscopy are presented for SDSS J125637.13-022452.4, one of only four L subdwarfs reported to date. These data confirm the low-temperature, metal-…
A new formal solution of the radiative transfer in arbitrary velocity fields
S. Knop, P. H. Hauschildt, E. Baron
We present a new formal solution of the Lagrangian equation of radiative transfer that is useful in solving the equation of radiative transfer in the presence of arbitrary velocity…
