Double-peaked supernovae

Through hydrodynamical ID simulations we explore two of the more promissing physical scenarios invoked to explain peculiar double-peaked supenovae. One consists of a double radioactive nickel distribution formed when some of this material is pushed out by a putative jet that is related to the supern...

One consists of a double radioactive nickel distribution formed when some of this material is pushed out by a putative jet that is related to the supernova explosion. The other scenario has only outer nickel, but the main peak is powered by a newly born magnetar. We present the whole evolution of the bolometric light curve for a helium-rich progenitor. The main goal is to compare the resulting bolometric light curves and to confirm the fact that, for some parameters, the two peaks are clearly departed, being the latter a brigther and broader main peak. A través de simulaciones hidrodinámicas ID, exploramos dos de los escenarios físicos más prometedores invocados para explicar las peculiares supernovas de doble pico. Uno consiste en una doble distribución de níquel radiactivo que se forma cuando parte de este material es expulsado por un supuesto chorro que está relacionado con la explosión de la supernova. El otro escenario solo tiene níquel exterior, pero el pico principal es impulsado por una magnetar recientemente formado. Presentamos toda la evolución de la curva de luz bolométrica para un progenitor rico en helio. El objetivo principal es comparar las curvas de luz bolométricas resultantes y confirmar el hecho de que, para algunos parámetros, los dos picos están claramente separados, siendo este último un pico principal más ancho y brillante.
