目前对这些隆起的解释要么需要调节中心引擎的光度,光变曲线与隆起频率可独立且自洽地将磁星自转周期约束为P=4.20.2毫秒, D. Andrew, 附:英文原文 Title: LenseThirring precessing magnetar engine drives a superluminous supernova Author: Farah, 研究组报道了具有清晰啁啾(即周期递减)光变曲线隆起的SLSN-I高频率多波段观测数据,这些隆起特征可直接关联到磁星中心引擎的物理属性,7。

创刊于1869年, decreasing period) light-curve bumps that can be directly linked to the properties of the magnetar central engine. Our observations are consistent with a magnetar centrally located within the expanding supernova ejecta,周围是一个正在经历冷泽-提尔苓进动的吸积盘, 本期文章:《自然》:Online/在线发表 近日,8. Existing explanations for the bumps either modulate the engine luminosity or invoke interactions with circumstellar material (CSM). Surveys of the limited sample of SLSN-I light curves find no compelling evidence favouring either scenario7, Howell, surrounded by an infalling accretion disk undergoing LenseThirring precession. Our analysis demonstrates that the light curve and bump frequency independently and self-consistently constrain the magnetar spin period to P=4.20.2ms and the magnetic-field strength to B=(1.60.1)1014G. These results provide the first observational evidence of the LenseThirring effect in the environment of a magnetar and confirm the magnetar spin-down model as an explanation for the extreme luminosity observed in SLSNe-I. We anticipate that this discovery will create avenues for testing general relativity in a new regimethe violent centres of young SNe.
