General Relativistic Radiative Transfer
S. Knop, P. H. Hauschildt, E. Baron
We present a general method to calculate radiative transfer including scattering in the continuum as well as in lines in spherically symmetric systems that are influenced by the ef…
On the Progenitor of Supernova 1987A
M. Parthasarathy, David Branch, E. Baron +1
A previously unpublished ultralow-dispersion spectrum of Sanduleak -69 202, the stellar progenitor of SN 1987A, is presented and the uncertain presupernova evolution of Sanduleak -…
On SN 2003fg: The Probable Super-Chandrasekhar-Mass SN Ia
David J. Jeffery, David Branch, E. Baron
Howell et al. have reported the discovery of SN Ia SN 2003fg (SNLS-03D3bb) and conclude that SN 2003fg is very likely a super-Chandrasekhar-mass SN Ia perhaps with a mass of order…
Goodness-of-Fit Tests DIFF1 and DIFF2 for Locally-Normalized Supernova Spectra
David J. Jeffery, Wesley Ketchum, David Branch +3
Two quantitative tests DIFF1 and DIFF2 for measuring goodness-of-fit between two locally-normalized supernova spectra are presented. Locally-normalized spectra are obtained by divi…
Hydrogen in Type Ic Supernovae?
David Branch, David J. Jeffery, Timothy R. Young +1
By definition, a Type Ic supernova (SN Ic) does not have conspicuous lines of hydrogen or helium in its optical spectrum. SNe Ic usually are modelled in terms of the gravitational…
A 3D radiative transfer framework: I. non-local operator splitting and continuum scattering problems
Peter H. Hauschildt, E. Baron
We describe a highly flexible framework to solve 3D radiation transfer problems in scattering dominated environments based on a long characteristics piece-wise parabolic formal sol…
