Can Effects of a Generalized Uncertainty Principle Appear in Compact Stars? by João Gabriel Galli Gimenez, Dimiter Hadjimichef, Peter Otto Hess, Marcelo Netz-Marzola, César A. Zen Vasconcellos

“…The corresponding results for the equation of state and the mass-radius relation for neutron stars are in tune with recent observations with a maximum mass around 2.5 M_⊙ and radius close to 12 km. …”

“…Interferometric observations of gravitational microlensing events offer an opportunity for precise, efficient, and direct mass and distance measurements of lensing objects, especially those of isolated neutron stars and black holes. However, such observations have previously been possible for only a handful of extremely bright events. …”

Dark I-Love-Q by Jing-Yi Wu, Wei Li, Xin-Han Huang, Kilar Zhang

“…Abstract For neutron stars, there exist universal relations insensitive to the equation of states, the so called I-Love-Q relations, which show the connections among the moment of inertia, tidal Love number and quadrupole moment. …”

Star shearing season: transient signals in wave-like dark matter experiments from black hole formation by Arturo de Giorgi, Joerg Jaeckel

“…Abstract Ordinary matter coupled to light weakly interacting bosons can lead to the formation of a macroscopic bosonic field in the vicinity of large matter concentrations such as ordinary or neutron stars. When these objects are turned into black holes due to a supernova or a binary merger this “hair” could be “shorn” off. …”

Strong-field QED effects on polarization states in dipole and quadrudipole pulsar emissions by Dong-Hoon Kim, Chul Min Kim, Sang Pyo Kim

“…Abstract Highly magnetized neutron stars have quantum refraction effects on pulsar emission due to the non-linearity of the quantum electrodynamics (QED) action. …”

Aspects of rotating anisotropic dark energy stars by O. P. Jyothilakshmi, Lakshmi J. Naik, V. Sreekanth

“…We also find that the dimensionless quadrupole moments of anisotropic dark energy stars corresponding to the canonical mass $${\bar{q}}_{1.4}$$ q ¯ 1.4 have a similar range of values as that of isotropic neutron stars and strange stars.…”

The stability of anisotropic compact stars influenced by dark matter under teleparallel gravity: an extended gravitational deformation approach by Sneha Pradhan, Piyali Bhar, Sanjay Mandal, P. K. Sahoo, Kazuharu Bamba

“…To validate our findings, we compare our model predictions with observational constraints, including GW190814 (with a mass range of $$2.5-2.67 M_{\odot }$$ 2.5 - 2.67 M ⊙ ) and neutron stars (NSTRs) such as EXO 1785-248 [mass= $$1.3_{-0.2}^{+0.2}~M_{\odot }$$ 1 . 3 - 0.2 + 0.2 M ⊙ ], 4U 1608-52 [mass= $$1.74_{-0.14}^{+0.14}~M_{\odot }$$ 1 . 74 - 0.14 + 0.14 M ⊙ ], and PSR J0952-0607 [mass= $$2.35_{-0.17}^{+0.17}~M_{\odot }$$ 2 . 35 - 0.17 + 0.17 M ⊙ ]. …”

Distinguishing Compact Objects in Extreme-Mass-Ratio Inspirals by Gravitational Waves by Lujia Xu, Shucheng Yang, Wenbiao Han, Xingyu Zhong, Rundong Tang, Yuanhao Zhang

“…Therefore, our findings suggest that it is possible to distinguish primordial black holes from white dwarfs, and, under certain conditions, neutron stars can also be differentiated from primordial black holes.…”
