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 …

Bosonic dark matter in neutron stars and its effect on gravitational wave signal

D Rafiei Karkevandi, S Shakeri, V Sagun, O Ivanytskyi - Physical Review D, 2022 - APS
We study an impact of self-interacting bosonic dark matter (DM) on various observable
properties of neutron stars (NSs). The analysis is performed for asymmetric DM with masses …

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

Tidal deformability of fermion-boson stars: Neutron stars admixed with ultralight dark matter

RF Diedrichs, N Becker, C Jockel, JE Christian… - Physical Review D, 2023 - APS
In this work, we investigate the tidal deformability of a neutron star admixed with dark matter,
modeled as a massive, self-interacting, complex scalar field. We derive the equations to …

[HTML][HTML] Snowmass2021 theory frontier white paper: Astrophysical and cosmological probes of dark matter

KK Boddy, M Lisanti, SD McDermott, NL Rodd… - Journal of High Energy …, 2022 - Elsevier
While astrophysical and cosmological probes provide a remarkably precise and consistent
picture of the quantity and general properties of dark matter, its fundamental nature remains …

Heating neutron stars with inelastic dark matter and relativistic targets

G Alvarez, A Joglekar, M Phoroutan-Mehr, HB Yu - Physical Review D, 2023 - APS
The dense environment of neutron stars makes them an excellent target for probing dark
matter interactions with the Standard Model. We study neutron star heating from capture of …

Dark matter effects on the properties of neutron stars: Compactness and tidal deformability

HM Liu, JB Wei, ZH Li, GF Burgio, HC Das, HJ Schulze - Physical Review D, 2024 - APS
We systematically study the observable properties of dark-matter admixed neutron stars with
arbitrary dark-matter fraction, employing a realistic nuclear equation of state in combination …

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 …

Scattering searches for dark matter in subhalos: neutron stars, cosmic rays, and old rocks

J Bramante, BJ Kavanagh, N Raj - Physical Review Letters, 2022 - APS
In many cosmologies dark matter clusters on subkiloparsec scales and forms compact
subhalos, in which the majority of Galactic dark matter could reside. Null results in direct …

Improved treatment of dark matter capture in neutron stars II: leptonic targets

NF Bell, G Busoni, S Robles… - Journal of Cosmology and …, 2021 - iopscience.iop.org
Neutron stars harbour matter under extreme conditions, providing a unique testing ground
for fundamental interactions. We recently developed an improved treatment of dark matter …
