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.…”
