New analysis of neutron star constraints on asymmetric dark matter

R Garani, Y Genolini, T Hambye - Journal of Cosmology and …, 2019 - iopscience.iop.org
Due to their extreme density and low temperature, neutron stars (NS) are efficient probes to
unveil interactions between standard model and dark matter (DM) particles. From elastic …

Neutron star observations of pseudoscalar-mediated dark matter

J Coffey, D McKeen, DE Morrissey, N Raj - Physical Review D, 2022 - APS
Scattering interactions between dark matter and Standard Model states mediated by
pseudoscalars are generically challenging to uncover at direct detection experiments due to …

Detecting bosonic dark matter with neutron stars

TN Maity, FS Queiroz - Physical Review D, 2021 - APS
What if the dark matter-nucleon scattering cross section is too small to be detected by direct
detection experiments? It is well known in the literature that some interactions lead to dark …

[HTML][HTML] Cooling of Neutron Stars admixed with light dark matter: A case study

MÁ Pérez-García, H Grigorian, C Albertus, D Barba… - Physics Letters B, 2022 - Elsevier
Abstract Neutron Stars (NSs) are born as hot, lepton-rich objects that evolve according to the
standard paradigm through subsequent stages where they radiate the excess of energy by …

Accretion-induced Collapse of Dark Matter Admixed White Dwarfs. I. Formation of Low-mass Neutron Stars

SC Leung, S Zha, MC Chu, LM Lin… - The Astrophysical …, 2019 - iopscience.iop.org
Recently observed pulsars with masses∼ 1.1 M⊙ challenge the conventional neutron star
(NS) formation path by core-collapse supernova (CCSN). Using spherically symmetric …

Gamma rays from dark mediators in white dwarfs

M Cermeño, MA Pérez-García - Physical Review D, 2018 - APS
We consider self-annihilation of dark matter, χ, into metastable mediators, Y, and their
subsequent decay into photons inside white dwarfs. We focus on reactions of the type χ χ¯→ …

Improved treatment of bosonic dark matter dynamics in neutron stars: consequences and constraints

K Dutta, D Ghosh… - Journal of Cosmology and …, 2024 - iopscience.iop.org
It is conceivable that a bosonic dark matter (DM) with non-gravitational interactions with SM
particles will be accumulated at the center of a neutron star (NS) and can lead to black hole …

Dark matter and bubble nucleation in old neutron stars

A Herrero, MA Pérez-García, J Silk, C Albertus - Physical Review D, 2019 - APS
We study the probability for nucleation of quark matter droplets in the dense cold cores of old
neutron stars induced by the presence of a self-annihilating dark matter component, χ. Using …

Dark Matter Effects on Stellar Populations in Globular Clusters

E Hassani, SMG Mousavi - arXiv preprint arXiv:2106.03398, 2021 - arxiv.org
According to the classical view of globular clusters, stars inside globular clusters are evolved
from the same giant molecular cloud. Then their stars' chemical compositions must be the …
