On the Maximum Energy Release from Formation of Static Compact Objects
Galaxies, 2023 Type II Supernova 1987A (SN 1987A), observed in 1987, released an energy of Q≈3×1053 erg. This huge energy is essentially the magnitude of gravitational potential or self-gravitational energy (PE) of a new born cold neutron star having a gravitational ...

Repeating fast radio bursts from collapses of the crust of a strange star
The Innovation, 2021 Summary: Strange stars (SSs) are compact objects made of deconfined quarks. It is hard to distinguish SSs from neutron stars as a thin crust composed of normal hadronic matter may exist and obscure the whole surface of the SS.

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.

Measuring Mass and Radius of the Maximum-mass Nonrotating Neutron Star
The Astrophysical Journal, 2023 The mass ( M _TOV ) and radius ( R _TOV ) of the maximum-mass nonrotating neutron star (NS) play a crucial role in constraining the elusive equation of state of cold dense matter and in predicting the fate of remnants from binary neutron star (BNS ...

Compact Objects and Accretion Disks [PDF]
, 2001 Recent developments in the spectropolarimetric study of compact objects, specifically black holes (stellar and massive) and neutron stars are reviewed. The lectures are organized around five topics: disks, jets, outflows, neutron stars and black holes.

Conformal motion for higher-dimensional compact objects
European Physical Journal C: Particles and Fields, 2023 In this work, we present a new framework for five-dimensional spherical symmetry anisotropic stars that admits conformal motion. The behaviour of model characteristic pressure, stress, density profile and surface tension is investigated with the ...

Nondetection of CHIME/Fast Radio Burst Sources with the Arecibo Observatory
The Astrophysical Journal, 2023 In this work, we present follow-up observations of two known repeating fast radio bursts (FRBs) and seven nonrepeating FRBs with complex morphology discovered with the CHIME/FRB project.

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 disk-wind models, and jet collimation in magnetic acceleration models.

A Tolman-like Compact Model with Conformal Geometry
Entropy, 2021 In this investigation, we study a model of a charged anisotropic compact star by assuming a relationship between the metric functions arising from a conformal symmetry.
