Description
We present a detailed study of the Type Ib/c SN 2010as based on
optical and near-infrared imaging and spectroscopy, plus radio
observations. The data span from about two weeks before to
about 150 days after maximum light. SN colors and spectra indicate
this object suffered considerable reddening by dust. Intermediate resolution
X-Shooter spectra cover the time of
maximum light and show multi-component interstellar absorption
lines. Pre-maximum spectra show large velocity variations in
Ca II and probable H lines. We use the multi-band data to derive
physical parameters for the progenitor object and explosion process.
