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 …

Confronting strange stars with compact-star observations and new physics

S Yang, C Pi, X Zheng, F Weber - Universe, 2023 - mdpi.com
Strange stars ought to exist in the universe according to the strange quark matter hypothesis,
which states that matter made of roughly equal numbers of up, down, and strange quarks …

Dark matter effects on neutron star properties

J Ellis, G Hütsi, K Kannike, L Marzola, M Raidal… - Physical Review D, 2018 - APS
We study possible effects of a dark matter (DM) core on the maximum mass of a neutron star
(NS), on the mass-radius relation and on the NS tidal deformability parameter Λ. We show …

Dark matter or regular matter in neutron stars? How to tell the difference from the coalescence of compact objects

M Hippert, E Dillingham, H Tan, D Curtin… - Physical Review D, 2023 - APS
The mirror twin Higgs model is a candidate for (strongly-interacting) complex dark matter,
which mirrors SM interactions with heavier quark masses. A consequence of this model are …

Effects of dark matter on the nuclear and neutron star matter

HC Das, A Kumar, B Kumar, SK Biswal… - Monthly Notices of …, 2020 - academic.oup.com
We study the dark matter (DM) effects on the nuclear matter (NM) parameters characterizing
the equation of states of super dense neutron-rich nucleonic matter. The observables of the …

Dark matter admixed neutron star properties in the light of X-ray pulse profile observations

Z Miao, Y Zhu, A Li, F Huang - The Astrophysical Journal, 2022 - iopscience.iop.org
The distribution of the dark matter (DM) in DM-admixed neutron stars (DANSs) is supposed
to result in either a dense dark core or an extended dark halo, subject to the DM fraction of …

[HTML][HTML] Search for dark matter effects on gravitational signals from neutron star mergers

J Ellis, A Hektor, G Hütsi, K Kannike, L Marzola… - Physics Letters B, 2018 - Elsevier
Motivated by the recent detection of the gravitational wave signal emitted by a binary
neutron star merger, we analyse the possible impact of dark matter on such signals. We …

Dark matter admixed neutron stars

B Kain - Physical Review D, 2021 - APS
Neutron stars could contain a mixture of ordinary nuclear matter and dark matter, such that
dark matter could influence observable properties of the star, such as its mass and radius …

Dark matter effect on realistic equation of state in neutron stars

G Panotopoulos, I Lopes - Physical Review D, 2017 - APS
In this work, we apply relativistic mean-field theory in neutron stars assuming that fermionic
dark matter is trapped inside the star and interacts directly with neutrons by exchanging …

Tidal Love numbers of novel and admixed celestial objects

M Collier, D Croon, RK Leane - Physical Review D, 2022 - APS
A subfraction of dark matter or new particles trapped inside celestial objects can significantly
alter their macroscopic properties. We investigate the new physics imprint on celestial …
