1 0 Ju n 20 09 Bolometric Light Curves for 33 Type II - Plateau Supernovae

چکیده
Using data of three well-observed type-II plateau supernovae (SNe II-P), SNe 1987A, 1999em and 2003hn; and two atmosphere models by Eastman et al. (1996) and Dessart & Hillier (2005b) we derive calibrations for bolometric corrections and effective temperature from BVI photometry. The typical scatter of the bolometric correction is 0.11 mag. With these results we obtain bolometric light curves and effective temperature evolution for a sample of 33 SNe II-P. The SN sample shows a range of 1 dex in plateau luminosity and plateau durations from 75 to 120 days. Comparing the shape of the transition between the plateau and the radioactive tail, we find that the size of the drop is in the range of 0.8 to 1.12 dex. Subject headings: supernovae: general — supernovae: individual (SN 1987A, SN 1999em, SN 2003hn)

Epochs of maximum light and bolometric light curves of type Ia supernovae
We present empirical fits to the UBVRI light curves of type Ia supernovae. These fits are used to objectively evaluate light curve parameters. We find that the relative times of maximum light in the filter passbands are very similar for most objects. Surprisingly the maximum at longer wavelengths is reached earlier than in the B and V light curves. This clearly demonstrates the complicated natu...

متن کاملBolometric Light Curves of Supernovae
The thermalized energy from the radioactive decays of Ni and Ni and their daughter nuclides power the light curves of supernovae near maximum light. The bolometric light curve gives us a fundamental understanding of the energy evolution of a supernova explosion and the amount of radioactive nuclides produced. In this review, I will discuss the bolometric evolution of the Type IIp supernovae SN1...
متن کاملThe Rise Times and Bolometric Light Curve of SN 1994D: Constraints on Models of Type Ia Supernovae
Using the published photometry and an empirical model of the temporal evolution of the apparent magnitudes in the UBVRI passbands, we have constructed a continuous optical bolometric, or “quasi-bolometric”, light curve of the well-observed Type Ia supernova SN 1994D. The optical bolometric light curve is found to have a maximum luminosity of about 8.8 × 1042 × ( D 13.7Mpc) 2 erg/s, which is rea...
متن کاملProperties of Type Ii Plateau Supernova Snls-04d2dc: Multicolor Light Curves of Shock Breakout and Plateau
Shock breakout is the brightest radiative phenomenon in a Type II supernova (SN). Although it was predicted to be bright, the direct observation is difficult due to the short duration and Xray/ultraviolet-peaked spectra. First entire observations of the shock breakouts of Type II Plateau SNe (SNe IIP) were reported in 2008 by ultraviolet and optical observations by the GALEX satellite and super...
