报告摘要:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I discuss effects of dense circustellar media on early emission of Type IIP supernovae and their implications. Type IIP supernovae are explosions of red supergiants. I focus on rise times of Type IIP supernovae. We performed numerical light-curve modeling of red supergiant explosions within circumstellar media and compared them to observations. We found that early light curves of Type IIP supernovae can be generally better explained when there are dense circumstellar media. Our results indicate that red supergiants generally have high mass-loss rates in the final decades before their explosions.
