Abstract:
CCD UBVRI photometry covering about 320 days is presented for the type
IIb SN 2008ax. Its photometric behavior is typical of core-collapse
SNe with low amount of hydrogen. The main photometric parameters are
derived and a comparison with SNe of similar types is reported.
Preliminary modeling is carried out, and the results are compared to
the observed light curves. The main parameters of the hydrodynamical
models are close to those used for SN IIb 1993J.
Description:
We started photometric monitoring of SN 2008ax 4 days after its
discovery and continued observations until 2009 January 23.
