Hypercritical Advection-dominated Accretion Flow
TL;DR: In this article, the authors studied the accretion disk that arises in hypercritical accretion onto a neutron star while it is in common envelope evolution with a massive companion, and they showed that neutrino cooling during the flow is negligible, satisfying very well the advection-dominating conditions.
Effective interactions of hyperons and mass-radius relation of neutron stars
TL;DR: In this article, the role of hyperons in a neutron star was examined based on the relativistic mean field approach and it was shown that hyperons induce a repulsive force and hardens the equation of state.
Gravitational waves from black hole-neutron star binaries: Effective Fisher matrices and parameter estimation using higher harmonics
TL;DR: In this paper, the authors present a method for computing an approximate Fisher matrix from variations in the ambiguity function on physically pertinent scales which depend on the relevant signal-to-noise ratio.
Kerr parameters for stellar mass black holes and their consequences for gamma-ray bursts and hypernovae

TL;DR: In this paper, it was shown that most soft X-ray transient (SXT) sources were subluminous given that they could use only a small part of the available rotational energy.
Kaon-nucleon scattering from chiral Lagrangians
TL;DR: In this article, the s-wave K±N scattering amplitude is computed up to one-loop order corresponding to next-to-nextto-leading order (or N2LO in short) in chiral perturbation with a heavy-baryon effective chiral Lagrangian.
