The impact of different magnetic braking prescriptions on the evolution of LMXBs
M. Echeveste, M. L. Novarino, O. G. Benvenuto +1
We revisit the evolution of low-mass close binary systems under different magnetic braking (MB) prescriptions. We study binaries with a neutron star accretor. During mass transfer…
Does PSR J1417-4402 system behave as a "Redback"?
M. A. De Vito, J. E. Horvath, O. G. Benvenuto
We study the present evolutionary status of the binary system containing the 2.66 ms pulsar PSR J1417-4402 in a 5.4 day orbit. This is the pulsar in the original source 3FGL J1417.…
The Unusual Super-Luminous Supernovae SN 2011kl and ASASSN-15lh
Melina C. Bersten, Omar G. Benvenuto, Mariana Orellana +1
Two recently discovered very luminous supernovae (SNe) present stimulating cases to explore the extents of the available theoretical models. SN 2011kl represents the first detectio…
Final Evolution and Delayed Explosions of Spinning White Dwarfs in Single Degenerate Models for Type Ia Supernovae
Omar G. Benvenuto, Jorge A. Panei, Ken'ichi Nomoto +2
We study the occurrence of delayed SNe~Ia in the single degenerate (SD) scenario. We assume that a massive carbon-oxygen (CO) white dwarf (WD) accretes matter coming from a compani…
The Evolution of Proto-Strange Stars
Omar G. Benvenuto, J. E. Horvath
We perform 1D calculations of neutrino opacities inside a young "strange star" assumed to be the result of the conversion process of a normal neutron object. We evaluate the delept…
The Type IIb Supernova 2011dh from a Supergiant Progenitor
Melina C. Bersten, Omar G. Benvenuto, Ken'ichi Nomoto +10
A set of hydrodynamical models based on stellar evolutionary progenitors is used to study the nature of SN 2011dh. Our modeling suggests that a large progenitor star ---with R ~200…
