Neutron Star Equation of State via Physics Informed Neural Network
Gabriel Bezerra, Veronica Dexheimer, Rodrigo Negreiros
We present the first application, to the best of our knowledge, of Physics-Informed Neural Networks (PINNs) to the neutron star equation-of-state (EOS) inverse problem. Two interac…
Sub-stellar Strange Quark Matter Objects: Predicting a New Class of Highly-Compact Candidates
Jonathan Joás Zapata Campos, Rodrigo Negreiros
We investigate the existence and stability of highly-compact sub-stellar objects composed of strange quark matter (SQM), focusing on finite-size strangelets with baryon number $A \…
Can the central compact object in HESS J1731--347 be indeed the lightest neutron star observed?
Shu-Rui Zhang, Jorge A. Rueda, Rodrigo Negreiros
The exceptionally low mass of for the central compact object (CCO) XMMU J173203.3 -- 344518 (XMMU J1732) in the supernova remnant (SNR) HESS J1731 -…
Dynamical instability of white dwarfs and breaking of spherical symmetry under the presence of extreme magnetic fields
J. G. Coelho, R. M. Marinho, M. Malheiro +4
Massive, highly magnetized white dwarfs with fields up to G have been observed and theoretically used for the description of a variety of astrophysical phenomena. Ultramagne…
