论文摘要
我探索了型IIP Supernova SN 2013F在冲击爆发后H型IIP Supernova SN 2013F上探索H $α$发射的不对称起源。从CS壳中，H $α$排放的球形模型考虑到超新星辐射的前旋转气体加速度，使我们能够成功地再现\ ha h $α$配置文件。负责H $α$不对称的主要因素是加速CS Preshock Gas的高速度（$ \ sim 3000 $ \，km s $^{ - 1} $）和低H $α$ sobolev光学深度，结合使用了H $α$ photosesion photosesion photosesion photosesion photosesion photosesion photosesion。
I explore the origin of an asymmetry of the H$α$ emission from a circumstellar (CS) shell around type IIP supernova SN 2013fs in the spectrum taken 10.3\,h after the shock breakout. A spherical model of the H$α$ emission from the CS shell that takes into account a preshock gas acceleration by the supernova radiation permits us to successfully reproduce the \ha H$α$ profile. Principal factors responsible for the H$α$ asymmetry are the high velocity of the accelerated CS preshock gas ($\sim 3000$\,km s$^{-1}$) and a low H$α$ Sobolev optical depth in a combination with an occultation of the H$α$ emission by the photosphere.
