Observable Signatures of Compact Objects
- Jorge Ovalle (Institute of Physics, Silesian University in Opava)
Kilonovae are transient events observed in Optical-Near IR band, powered by radioactive decay of elements produced through r-process nucleosynthesis. They form in the ejecta emitted in binary neutron star mergers. The kilonova signal may accompany the gravitational wave emission and potential gamma-ray burst signal, such as in the well known event discovered as GW-GRB 170817. I will discuss...
Disc structures around black holes are of great importance in astrophysics. The usual simplification of most accreting models is neglecting the disc's self-gravitation. However, in many situations, numerous disc properties may be highly sensitive to the gravitational field. We present a full metric describing the field of a thin disc and a Schwarzschild black hole. The disc density profiles...
The purpose of this talk is discuss the possibility of detection of dark matter through multiple observations of compact stars and related phenomena. Recent scientific and technological developments have allowed for a better study of the nature of these astrophysical objects, in particular of the equation of state (EoS). As we advance on the quest for clarification of the neutron star internal...
Disk reflection and disk wind are two seemingly disconnected phenomena in the X-ray spectra of Black Hole X-ray binaries, providing independent probes to constrain important physical parameters associated with the accretion disks (e.g., inclination and density). A synergy between reflection and absorption spectroscopy, therefore, can provide an unprecedented insight into the physical...
