Webof PTF12dam and iPTF13dcc; Liu et al. (2024) develop a multiple CSI model involving the collisions between the ejecta and the CSM shells or winds locating at different sites and use these models to fit the LCs of iPTF15esb and iPTF13dcc. In this paper, we study two hydrogen-poor SNe, PS1-12cil and SN 2012aa. PS1-12cil is an SLSN I discovered ... Webtask dataset model metric name metric value global rank remove

WebIn contrast, the long-duration (>30days) early excess emission in iPTF13dcc, whose brightness competes with that of the main peak, appears to be of a different nature. We construct bolometric light curves for both targets, and fit a variety of light-curve models to both the early bump and main peak in an attempt to understand the nature of http://export.arxiv.org/abs/1609.08145v1 osprey avon co

WebSep 26, 2016 · A model combining a shock breakout in an extended envelope with late-time magnetar energy injection provides a reasonable fit to the iPTF13dcc observations. … WebSep 26, 2024 · The Intermediate Palomar Transient Factory reported the discovery of an unusual type II-P supernova iPTF14hls. Instead of an ∼100 day plateau as observed for ordinary type II-P supernovae, the light curve of iPTF14hls has at least five distinct peaks, followed by a steep decline at ∼1000 days since discovery. WebWell sampled light curves of SN2015bn and iPTF13dcc have also resulted in discov- eries of LC undulations of SLSNe-I, suggesting possible ejecta interaction with H-poor CSM (Nicholl et al. 2016; Vreeswijk et al. 2024). In this paper, we report two new SLSNe-I events, iPTF15esb and iPTF16bad, showing late-time H emis- sion, similar to iPTF13ehe. osprey capital investment
