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…
Classification of Compact Stars via Machine Learning and Neural Network Models
D. Neraki, G. Koufetidis, I. Stergakis +2
Recent advances in multimessenger astronomy, particularly through gravitational-wave observations of compact-object mergers, have significantly improved our understanding of dense…
Neutron Dark Decay and Exotic Compact Objects
M. Vikiaris, V. Petousis, M. Veselsky +1
Recent measurements of the compact star XTE J1814-338, with a mass of and a radius of alongside those of HESS J173…
How the HESS J1731-347 event could be explained using condensation
M. Veselsky, P. S. Koliogiannis, V. Petousis +2
The recent observation of a compact star with a mass of and a radius of km, located within the supernova remnant H…
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…
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…
Colour-Flavour Locked Quark Stars in Light of the Compact Object in HESS J1731-347 and the GW190814 Event
P. T. Oikonomou, Ch. C. Moustakidis
The central compact object within HESS J1731- 347 possesses unique mass and radius properties that renders it a compelling candidate for a self-bound star. In this research, we exa…
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…
