Abstract
We report on the results of our low resolution spectroscopic observations during the 2011 outburst of the recurrent nova T Pyx. Our observations were performed from 0.19 days to 34 days after the eruption discovered by M. Linnolt. We found Wolf-Rayet like features in our spectrum during the initial rising phase on <em>t</em> = 0.19 d. Following spectral developments are consistent with previous works. We discuss that the early phase of T Pyx is divided into three stages, a short lived WR-like stage, He/N stage and Fe II stage.
Highlights
The initial rising phase of novae is a very intriguing phase in the point of view of thermonuclear runaway and development of spectral features
Low resolution spectroscopic observations in past outbursts were performed around their visual maximum (e.g., Adams and Joy 1920, Joy 1945, and Catchpole et al 1969)
Recurrent novae are classified into three types, the U Sco, the RS Oph- and the T Pyx-types, based on the light curves and spectroscopic features (Anupama et al 2008)
Summary
The initial rising phase of novae is a very intriguing phase in the point of view of thermonuclear runaway and development of spectral features. The study in the early spectroscopic observations and photometry revealed that T Pyx showed rare hybrid spectral classification types (Williams 1992), He/N - Fe II - He/N transition (e.g. Izzo et al 2012, Imamura and Tanabe 2012, Surina et al 2014). We focused on the Wolf-Rayet feature in the initial rising phase on t = 0.19 d (2011 April 14.48) and following developments of spectral features from t = 2 d to t = 34 d.
