Infrared and optical study of the type Ia SN 1998bu in M96.
Abstract
The type Ia SN 1998bu was discovered in the galaxy M96 on 9 May 1998. It is one of the closest type Ia events of modern times and good temporal coverage has been achieved. Moreover its distance is well-determined. The authors describe some of the first-season photometric and spectroscopic observations. While SN 1998bu is unusually highly reddened, they can still deduce that it was a typical type Ia event. Preliminary analysis suggests that for an H0 of about 60 km s-1Mpc-1, its (de-reddened) peak luminosity, light curve shape and spectroscopic behaviour confirms the relationships found between these parameters in other classic type Ia supernovae.
