Scientific paper

We propose to continue NAPA observations of nearby core-collapse supernovae (SNe) to: (1) Determine the physics of SNe through the study of the mass-loss rate, absorption mechanisms, and density distribution of the circumstellar medium (CSM) laid down by the pre-SN stellar wind; (2) Improve our understanding of the various subgroupings (Type Ib, Ic, IIL, IIP, IIn, IIb) which characterise the range of SN progenitor systems; and (3) Provide targets for Chandra/Swift X-ray ToO which is sensitive to the thermal emission from the SN shock and, thus, complementary to the non-thermal radio observations. In 2010APRS we detected (CBET 2242) and have been monitoring at 9.0 and 5.5 GHz SN 2010as in NGC 6000 at a distance of 30 Mpc, something not possible without CABB.
