Optimal inference of episodic stellar mass loss rates from real polarimetric and absorption data with noise and sparse sampling.
CALVINI P., BERTERO M. and BROWN J.C.
Abstract (from CDS):
The inverse problem of evaluating the axisymmetric stellar mass loss rate and oblateness during an episodic event, from observations of broad band scattering polarization and absorption spectrum line strength, is analyzed. In particular, a new inversion algorithm is developed to provide the optimal approach to the inversion problem in realistic cases where the data are noisy and sparsely sampled. Implementation of the method is presented for simulated data and for real data on a mass loss episode for the star ω Orionis.
