Diagnosis of Circumstellar Matter Structure in Interaction-powered Supernovae with Hydrogen Line Feature

Some supernovae (SNe) are powered by collision of the SN ejecta with a dense circumstellar matter (CSM). Their emission spectra show characteristic line shapes of combined broad emission and narrow P-Cyg lines, which should closely relate to the CSM ...

THREE-DIMENSIONAL MODELS OF EMBEDDED HIGH-MASS STARS: EFFECTS OF A CLUMPY CIRCUMSTELLAR MEDIUM

, 2005
We use three-dimensional radiative transfer models to show the effects of clumpy circumstellar material on the observed infrared colors of high-mass stars embedded in molecular clouds.
