Time-dependent radiative transfer calculations for supernovae

In previous papers we discussed results from fully time-dependent radiative transfer models for core-collapse supernova (SN) ejecta, including the Type II-peculiar SN 1987A, the more ‘generic’ SN II-Plateau, and more recently Type IIb/Ib/Ic SNe. Here we describe the modifications to our radiative modelling code, CMFGEN, which allowed those studies to be undertaken. The changes allow for time-de...

Comparison of Recalibrated Atmospheric Emitted Radiance Interferometer Observations with Line-by-Line Radiative Transfer Model Calculations

The comparison of recalibrated spectra from the atmospheric emitted radiance interferometer prototype (AERI-00) and lineby-line radiative transfer model (LBLRTM) calculations show much smaller differences in the 800-1200 cm atmospheric -1 window region under “clear conditions” compared with the preliminary calibrated data. Results indicate that the new AERI-00 data is in good agreement with sim...

E$cient eigenvalue calculations in radiative transfer

An e$cient method is used to compute the eigenvalues required in a discrete-ordinates solution to a special class of radiative-transfer problems. The basis for this computation is an algorithm for "nding eigenvalues of a matrix that consists of the sum of a diagonal matrix and a rank-one matrix, a form that can arise in a discrete-ordinates solution of some basic transport problems. To illustra...

On Discrete Spectrum Calculations in Radiative Transfer

The discrete spectrum for each component problem in a Fourier decomposition of the equation of transfer is analyzed for the case of an Lth-order scattering law. The problem of determining the number of zeros of the dispersion function for each Fourier-component problem and the problem of computing all of these zeros are formulated and resolved in terms of Sturm sequences. Computational aspects ...

Parallel Load Balancing Heuristics for Radiative Heat Transfer Calculations

The computation of radiative effects by the Photon Monte Carlo method is computationally demanding, especially when complex, nongray absorption models are employed. To solve such computationally expensive problems we have developed a parallel software framework for the photon Monte Carlo method based on ray tracing to compute radiative heat transfer effects. The central problem with obtaining s...
