Title |
Quark-Novae : Signatures in Astrophysical Data and Implications to Compact Stars | |||||
| Coauthors | ||||||||
|
Abstract |
After a brief account of the physics of the Quark-Nova (explosive transition of a neutron star to a quark star due to quark deconfinement), I will present indirect observational evidence of the Quark-Nova in astrophysical data (e.g. superluminous SNe, low-mass X-ray binaries). I will focus on clues in SGRs/AXPs data with special emphasis on the 13 keV emission feature and ``anti-glitches" in AXPs. I will discuss how this data, in the context of the QN model, can be used to constraint the equation of state of nuclear/neutron matter and infer conditions for the onset of quark matter inside neutron stars. |

Title |
Quark-Novae : Observational Signatures and Implications to Compact Binaries | |||||
| Coauthors | ||||||||

Abstract |
After a brief account of the physics of the Quark-Nova (explosive transition of a neutron star to a quark star due to quark deconfinement), I will present indirect observational evidence of the Quark-Nova in Super-Luminous Supernovae and in the context of the origin of heavy elements (r-process nucleosynthesis). I will then present our modelling of Quark-Novae occurring in compact binaries (with a neutron star and a compact or a normal companion) with particular attention to systems involving a CO white dwarf companion (with implications to Cosmology) and to systems involving a He donor (with implications to He-HMXBs). |
