Dark matter in compact stars

J Bramante, N Raj - Physics Reports, 2024 - Elsevier
WDs and neutron stars are far-reaching and multi-faceted laboratories in the hunt for dark
matter. We review detection prospects of wave-like, particulate, macroscopic and black hole …

Faint light of old neutron stars and detectability at the James Webb Space Telescope

S Chatterjee, R Garani, RK Jain, B Kanodia… - Physical Review D, 2023 - APS
Isolated ideal neutron stars (NS) of age> 10 9 yr exhaust thermal and rotational energies
and cool down to temperatures below O (100) K. Accretion of particle dark matter (DM) by …

Exoplanets as sub-GeV dark matter detectors

RK Leane, J Smirnov - Physical Review Letters, 2021 - APS
We present exoplanets as new targets to discover dark matter (DM). Throughout the Milky
Way, DM can scatter, become captured, deposit annihilation energy, and increase the heat …

Celestial-body focused dark matter annihilation throughout the galaxy

RK Leane, T Linden, P Mukhopadhyay, N Toro - Physical Review D, 2021 - APS
Indirect detection experiments typically measure the flux of annihilating dark matter (DM)
particles propagating freely through galactic halos. We consider a new scenario where …

Dark kinetic heating of neutron stars and an infrared window on WIMPs, SIMPs, and pure Higgsinos

M Baryakhtar, J Bramante, SW Li, T Linden, N Raj - Physical review letters, 2017 - APS
We identify a largely model-independent signature of dark matter (DM) interactions with
nucleons and electrons. DM in the local galactic halo, gravitationally accelerated to over half …

Floating dark matter in celestial bodies

RK Leane, J Smirnov - Journal of Cosmology and Astroparticle …, 2023 - iopscience.iop.org
Dark matter (DM) can be captured in celestial bodies after scattering and losing sufficient
energy to become gravitationally bound. We derive a general framework that describes the …

Can LIGO Detect Nonannihilating Dark Matter?

S Bhattacharya, B Dasgupta, R Laha, A Ray - Physical review letters, 2023 - APS
Dark matter (DM) from the galactic halo can accumulate in neutron stars and transmute them
into sub-2.5 M⊙ black holes if the dark matter particles are heavy, stable, and have …

Improved treatment of dark matter capture in neutron stars

NF Bell, G Busoni, S Robles… - Journal of Cosmology and …, 2020 - iopscience.iop.org
Neutron stars provide a cosmic laboratory to study the nature of dark matter particles and
their interactions. Dark matter can be captured by neutron stars via scattering, where kinetic …

Low mass black holes from dark core collapse

B Dasgupta, R Laha, A Ray - Physical Review Letters, 2021 - APS
Unusual masses of black holes being discovered by gravitational wave experiments pose
fundamental questions about the origin of these black holes. Black holes with masses …

Nucleon structure and strong interactions in dark matter capture in neutron stars

NF Bell, G Busoni, TF Motta, S Robles, AW Thomas… - Physical Review Letters, 2021 - APS
We outline two important effects that are missing from most evaluations of the dark matter
capture rate in neutron stars. As dark matter scattering with nucleons in the star involves …
