Impact of Kaon Condensation on the Thermal Evolution of the CCO in HESS J1731--347 Supernova Remnant
D. G. Nanopoulos, P. S. Koliogiannis, V. Petousis +2
Recent analyses of the central compact object in the HESS J1731--347 supernova remnant suggest an unusual combination of a low mass and small radius, while its thermal emission ind…

Neutron Star with Dark Matter Admixture: A Candidate for Bridging the Mass Gap
M. Vikiaris, V. Petousis, M. Veselsky +1
Neutron stars, white dwarfs and black holes are the after death remnants of massive stars. However, according to the most recent observations, the neutron stars maximum mass is bet…
Configurational entropy and stability conditions of fermion and boson stars
P. S. Koliogiannis, M. Vikiaris, C. Panos +3
In a remarkable study by M. Gleiser and N. Jiang [Phys. Rev. D {\bf 92}, 044046, 2015], the authors demonstrated that the stability regions of neutron stars, within the framework o…
Supramassive dark objects with neutron star origin
M. Vikiaris, V. Petousis, M. Veselsky +1
Till today, the nature of Dark Matter (DM) remains elusive despite all our efforts. This missing matter of the universe has not been observed by the already operating DM direct-det…
Constraints for the X17 boson from compacts objects observations
A. Kanakis-Pegios, V. Petousis, M. Veselsky +2
We investigate the hypothetical X17 boson on neutron stars and Quark Stars (QSs) using various hadronic Equation of States (EoSs) with phenomenological or microscopic origin. Our a…
Investigating Possible Existence of Hyper-Heavy Nuclei in Neutron Star Environment
M. Veselsky, V. Petousis, Ch. C. Moustakidis +2
The synthesis of hyper-heavy elements is investigated under conditions simulating neutron star environment. The Constrained Molecular Dynamics (CoMD) approach is used to simulate l…
QED Meson Description of the X17 and Other Anomalous Particles
Cheuk-Yin Wong
The X17 particle, the E38 particle, and the anomalous soft photons are anomalous particles because they do not appear to belong to any known Standard Model families. We propose a Q…
Neutron star structure with nuclear force mediated by hypothetical X17 boson
Vlasios Petousis, Martin Veselsky, Jozef Leja
A reported MeV boson, which has been proposed as an explanation to the Be and He anomaly, is investigated in the context of its possible influence to neutron sta…
Anomaly in decay of 8Be and 4He -- can an observed light boson mediate low energy nucleon-nucleon interactions ?
M. Veselsky, V. Petousis, J. Leja
We present a hypothesis that the anomaly in the folding angle distribution of electron-positron pairs, emitted in the decay of the excited levels of nucleus Be and He c…
