The Type IIb SN 2008ax: spectral and light curve evolution
We present spectroscopy and photometry of the He-rich supernova (SN) 2008ax. The earlytime spectra show prominent P-Cygni H lines, which decrease with time and disappear completely about 2 months after the explosion. In the same period He I lines become the most prominent spectral features. SN 2008ax displays the ordinary spectral evolution of a Type IIb supernova. A stringent pre-discovery lim...
متن کاملThe type IIb SN 2008ax: the nature of the progenitor
A source coincident with the position of the type IIb supernova (SN) 2008ax is identified in pre-explosion HST WFPC2 observations in three optical filters. We identify and constrain two possible progenitor systems: (1) a single massive star that lost most of its hydrogen envelope through radiatively driven mass loss processes, prior to exploding as a helium-rich Wolf-Rayet star with a residual ...
متن کامل23 Ghz Vlbi Observations of Sn 2008ax 23 Ghz Vlbi Observations of Sn 2008ax (research Note)
We report on phase-referenced 23 GHz Very-Long-Baseline-Interferometry (VLBI) observations of the type IIb supernova SN 2008ax, made with the Very Long Baseline Array (VLBA) on 2 April 2008 (33 days after explosion). These observations resulted in a marginal detection of the supernova. The total flux density recovered from our VLBI image is 0.8±0.3 mJy (one standard deviation). As it appears, t...
متن کاملThe He-rich stripped-envelope core-collapse supernova 2008ax
Extensive optical and near-infrared (NIR) observations of the Type IIb supernova (SN IIb) 2008ax are presented, covering the first year after the explosion. The light curve is mostly similar in shape to that of the prototypical SN IIb 1993J, but shows a slightly faster decline rate at late phases and lacks the prominent narrow early-time peak of SN 1993J. From the bolometric light curve and eje...
متن کاملThe early spectral evolution of SN 2004dt
Aims. We study the optical spectroscopic properties of Type Ia Supernova (SN Ia) 2004dt, focusing our attention on the early epochs. Methods. Observation triggered soon after the SN 2004dt discovery allowed us to obtain a spectrophotometric coverage from day −10 to almost one year (∼353 days) after the B band maximum. Observations carried out on an almost daily basis allowed us a good sampling ...
