Rotational Mass of Anisotropic Neutron Stars in Rastall Gravity
The rotational mass of anisotropic neutron stars is significantly impacted by the Rastall gravity parameter and the anisotropic strength, with the anisotropic strength being the dominant factor. The mass constraints of observed neutron stars, including the heaviest known, can be satisfied by the model with strong anisotropic strength.
Exotic Strange Stars Admixed with Mirror Dark Matter: Explaining the Peculiar Observations of XTE J1814-338 and Other Neutron Star Candidates
The presence of mirror dark matter can explain the unusual mass and radius measurements of compact objects like XTE J1814-338, which challenge conventional neutron star models.
Discovery of a Millisecond Pulsar Associated with the Globular Cluster Terzan 6
The discovery of a 5.33 millisecond pulsar, PSR J1750-3116A, likely associated with the globular cluster Terzan 6, which has an exceptionally high stellar encounter rate suggesting it should harbor dozens of pulsars.
Gravitational Collapse of Accreting Neutron Stars in Binary-Driven Hypernovae
Accreting neutron stars in binary-driven hypernovae can reach the critical mass for gravitational collapse into a black hole, with the occurrence time depending on the initial angular momentum and accretion efficiency.
Detailed Multi-Year Scintillation Studies of Eight Canonical Pulsars
Scintillation analyses of eight canonical pulsars over 2.5 years reveal new insights into the structure and evolution of the interstellar medium along their lines of sight.
Expected Gamma-Ray Burst Detection Rates and Redshift Distributions for the BlackCAT CubeSat Mission
The BlackCAT CubeSat mission is expected to detect a mean of 42 long-duration gamma-ray bursts per year, with 6.7% to 10% of these at redshifts z > 3.5.
A Catalog of Synchrotron-Emitting X-ray Filaments Powered by Pulsars
Pulsars can power extended, linear X-ray filaments through the escape of ultra-relativistic electrons and positrons from their bow shocks, which then radiate synchrotron emission along the ambient magnetic field lines.
TIC 290061484: A Triply Eclipsing Quadruple Star System with the Shortest Known Outer Period of 24.5 Days
TIC 290061484 is a triply eclipsing quadruple star system with the shortest known outer period of only 24.5 days, significantly shorter than the previous record holder.
Modeling the Magnetized Winds and Star-Planet Interactions of M-type Stars
The mass loss rate and wind properties of M-type stars are poorly constrained, but crucial for understanding the environment of their orbiting exoplanets. This work proposes a modeling strategy to estimate the mass loss rate, wind speed, and radiative losses of M-dwarf stellar winds, with a focus on the TRAPPIST-1 and Proxima Centauri systems.
Modeling X-ray Transit Profiles of Exoplanets Using an Extended Coronal Emission Model
We present an adaptation of the exoplanet transit model code batman to generate X-ray transit profiles, using an isothermal, radially symmetric coronal emission model. This enables the relatively fast generation of X-ray light curves based on coronal and planet properties.
