High mass of the type IIP supernova 2004et inferred from hydrodynamic modeling
Context. Previous studies of type IIP supernovae have inferred that progenitor masses recovered from hydrodynamic models are higher than 15 M⊙. Aims. To verify the progenitor mass of this supernova category, we attempt a parameter determination of the well-observed luminous type IIP
متن کاملProgenitor mass of the type IIP supernova 2005 cs
Context. The progenitor mass of type IIP supernova can be determined from either hydrodynamic modeling of the event or pre-explosion observations. Aims. To compare these approaches, we determine parameters of the sub-luminous supernova 2005cs and estimate its progenitor mass. Methods. We compute the hydrodynamic models of the supernova to describe its light curves and expansion velocity data. R...
متن کاملAn optimal hydrodynamic model for the normal Type IIP supernova 1999em
Context. There is still no consensus about progenitor masses of Type IIP supernovae. Aims. We study a normal Type IIP SN 1999em in detail and compare it to a peculiar Type IIP SN 1987A. Methods. We computed the hydrodynamic and time-dependent atmosphere models interpreting simultaneously both the photometric and spectroscopic observations. Results. The bolometric light curve of SN 1999em and th...
متن کاملNi Ejecta and Polarization in Type Iip Supernova 2004dj
I study a problem, whether the asymmetry of a 56 Ni ejecta that results in the asymmetry of the Hα emission line at the nebular epoch of the type IIP su-pernova SN 2004dj is able also to account for the recently detected polarization of the supernova radiation. I developed a model of the Hα profile and luminos-ity with a nonthermal ionization and excitation taken into account adopting an asymme...
متن کاملVlt Detection of a Red Supergiant Progenitor of the Type Iip Supernova 2008bk
We report the identification of a source coincident with the position of the nearby type II-P supernova (SN) 2008bk in high quality optical and near-infrared pre-explosion images from the ESO Very Large Telescope (VLT). The SN position in the optical and near-infrared pre-explosion images is identified to within about ±70 and ±40 mas, respectively, using post-explosion Ks-band images obtained w...
