| 英文摘要 | Abstract we study the most luminous known supernova (sn) associated with a gamma-ray burst (grb), sn?2011kl. the photospheric velocity of sn?2011kl around peak brightness is 21,000?±?7000 km s?1. owing to different assumptions related to the light-curve (lc) evolution (broken or unbroken power-law function) of the optical afterglow of grb?111209a, different techniques for the lc decomposition, and different methods (with or without a near-infrared contribution), three groups derived three different bolometric lcs for sn?2011kl. previous studies have shown that the lcs without an early-time excess preferred a magnetar model, a magnetar+56ni model, or a white dwarf tidal disruption event model rather than the radioactive heating model. on the other hand, the lc shows an early-time excess and dip that cannot be reproduced by the aforementioned models, and hence the blue-supergiant model was proposed to explain it. here, we reinvestigate the energy sources powering sn?2011kl. we find that the two lcs without the early-time excess of sn?2011kl can be explained by the magnetar+56ni model, and the lc showing the early excess can be explained by the magnetar+56ni model taking into account the cooling emission from the shock-heated envelope of the sn progenitor, demonstrating that this sn might primarily be powered by a nascent magnetar. |
