摘要: We constrain the explosion and circumstellar properties at 2012b event of SN 2009ip based on its late-phase bolometric light curve recently reported. The energy ejected mass are estimated as 0.01 Msun 2e49 erg, respectively. medium is assumed to have two components: an inner shell outer wind. which likely created 2012a has 0.2 Msun. wind by loss before ejection, progenitor had mass-loss rate about 0.1 Msun/yr with velocity 550 km/s event. indicate that not caused a regular supernova.
