Jets from compact objects [PDF]
Symposium - International Astronomical Union, 2000 Some topics in the theory of jets are reviewed. These include jet precession, unconfined jets, the origin of knots, the internal shock model as a unifying theme from protostellar jets to Gamma-ray bursts, relations between the Blandford-Znajek and MHD ...

Compact objects and the swampland [PDF]
Journal of High Energy Physics, 2019 Recently, two simple criteria were proposed to assess if vacua emerging from an effective scalar field theory are part of the string “landscape” or “swampland”.

Relativistic Compact Objects in Isotropic Coordinates [PDF]
Pramana, 2005 We present a matrix method for obtaining new classes of exact solutions for Einstein's equations representing static perfect fluid spheres. By means of a matrix transformation, we reduce Einstein's equations to two independent Riccati type differential ...

Evolution and Merging of Binaries with Compact Objects [PDF]
Physics Reports, 2005 In the light of recent observations in which short gamma-ray bursts are interpreted as arising from black-hole(BH), neutron-star(NS) or NS-NS mergings we would like to review our research on the evolution of compact binaries, especially those containing ...

Compact objects in entangled relativity [PDF]
Physical Review D, 2021 We describe the first numerical Tolman-Oppenheimer-Volkoff solutions of compact objects in entangled relativity, which is an alternative to the framework of general relativity that does not have any additional free parameter. Assuming a simple polytropic equation of state and the conservation of the rest-mass density, we notably show that, for any ...

Rates of compact object coalescences [PDF]
Living Reviews in Relativity, 2022 AbstractGravitational-wave detections are enabling measurements of the rate of coalescences of binaries composed of two compact objects—neutron stars and/or black holes. The coalescence rate of binaries containing neutron stars is further constrained by electromagnetic observations, including Galactic radio binary pulsars and short gamma-ray bursts ...

On thermodynamics of compact objects
Classical and Quantum Gravity, 2023 Abstract With the recent progress in observations of astrophysical black holes, it has become more important to understand in detail the physics of strongly gravitating horizonless objects. If the objects identified in the observations are indeed horizonless and ultracompact, high curvature effects may become important, and their ...

The Astrophysical Journal, 2023 Recent simulations find that hot gas accretion onto compact accretors is often highly turbulent and diskless, and shows a power-law density profile with slope α _ρ ≈ −1.
