NED Abstract

Copyright by Royal Astronomical Society. 2006MNRAS.366..682S Photometric study of type Ia supernova SN 2002hu Sahu, D. K.; Anupama, G. C.; Prabhu, T. P. Abstract. Optical UBVRI photometry of the type Ia supernova (SN Ia) SN 2002hu covering the period from -2 to +73d since B maximum is presented. The supernova reached at maximum brightness in B on JD2452591.78 +/- 0.5 with an apparent magnitude of 16.83 +/- 0.02mag and a relatively blue colour (B-V) =-0.08 +/- 0.04mag. The luminosity decline rate of {DELTA}m_15_(B) = 1.00 +/- 0.05 indicates an absolute B magnitude at maximum of M^max^_B_=-19.38 +/- 0.3. The estimated absolute B magnitude, together with the photometric evolution, indicate SN 2002hu was slightly overluminous compared to the average SNe Ia. The distance modulus to the parent galaxy is estimated to be {mu}= 36.04 +/- 0.20. Key words: supernovae: general, supernovae: individual: SN 2002hu, galaxies: individual: MCG+6-6-12
