Supernova 2009P in Pgc 34730
Abstract
U. K. Gurugubelli, G. C. Anupama, D. K. Sahu, and A. Kaur, Indian Institute of Astrophysics, Bangalore, report that a spectrum (range 360-750 nm) of 2009P (cf. CBETs 1674, 1680), obtained on Jan 30.5 UT with the Indian Astronomical Observatory's 2-m Himalayan Chandra Telescope (+ HFOSC), shows it to be a 1991T-like type-Ia supernova. Using the SNID code (Blondin and Tonry 2007, Ap.J. 666, 1024), the spectrum of 2009P is found to be similar to that of SN 1999aa about one day before maximum light. Adopting a recession velocity of 7526 km/s for the host galaxy (de Vaucouleurs et al. 1991, Third Reference Catalogue of Bright Galaxies), the blue-shifted velocity of the Si II 635.5-nm absorption is estimated to be approximately 14000 km/s.
