NED Abstract

Copyright by Royal Astronomical Society. 2008MNRAS.389..706M Photometric and spectroscopic study of a highly reddened type Ia supernova SN 2003hx in NGC 2076 Misra, Kuntal; Sahu, D. K.; Anupama, G. C.; Pandey, Kavita Abstract. We present UBVRI CCD photometry and optical spectra of the type Ia supernova SN 2003hx which appeared in the galaxy NGC 2076, obtained till ~ 146 d after the epoch of B-band maximum. The supernova reached at maximum brightness in B band on JD 2452893 +/- 1.0 with an apparent magnitude of 14.92 +/- 0.01 mag which was estimated by making template fits to the light curves. SN 2003hx is an example of a highly reddened supernova with E(B - V) = 0.56 +/- 0.23. We estimate R_v_ = 1.97 +/- 0.54 which indicates the small size of dust particles as compared to their galactic counterparts. The luminosity decline rate is {DELTA}m_15_(B) = 1.17 +/- 0.12 mag and the absolute B-band magnitude obtained from the luminosity versus decline rate relation (Phillips et al. 1999) is M^B^_max_ = -19.20 +/- 0.18 mag. The peak bolometric luminosity indicates that ~0.66M_sun_ mass of ^56^Ni was ejected by the supernova. The spectral evolution indicates the supernova to be a normal type Ia event. Key words: supernovae: general, supernovae: individual: SN 2003hx, galaxies: individual: NGC 2076
