Early Bolometric Luminosity of SN 2013fs without Photometry


A novel method is proposed for the reconstruction of the early bolometric light curve for supernovae IIP with the available set of H\(\alpha\) emission spectra on the first day after the shock breakout. The method uses the effect of radiative acceleration of the preshock circumstellar gas that is manifested in broad H\(\alpha\) wings. The efficiency of the method is demonstrated in the case of SN 2013fs for which the spectra were taken between 6 and 10 h after the shock breakout. An important feature of this method is that it does not require any photometry, distance, and extinction.
