Abstract

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.

没有光度法的SN 2013fs的早期Bolometric光度

摘要

提出了一种新的方法来重建超新星IIP的早期辐射热光曲线,该方法具有 在冲击爆发后第一天可用的H \(\ alpha \)发射光谱集。该方法利用了在宽H \(\ alpha \) 机翼中表现出的震前卫星气体的辐射加速效应。在SN 2013fs的情况下证明了该方法的效率,该频谱是在冲击爆发后6到10 h之间拍摄的。该方法的一个重要特征是不需要任何测光,距离和消光。
