Rotational enhancement and stability of protoquark stars during thermal evolution

Adamu Issifu, Andreas Konstantinou, Prashant Thakur +1

We present the first systematic study of rigidly rotating protoquark stars based on isentropic equations of state (EOS) within the density-dependent quark mass (DDQM) framework. Us…

Rotational effects in quark stars: comparing different models

Adamu Issifu, Andreas Konstantinou, Franciele M. da Silva +1

We investigate the rotational properties of self-bound strange quark stars using two representative quark matter equations of state (EOS): the vector MIT bag model and the density-…

Rotating Neutron Stars with Dark Matter Halos

Shafayat Shawqi, Andreas Konstantinou, Sharon M. Morsink

If dark matter (DM) exists in halos around rotating neutron stars (NSs), it will be essential to understand the effects of rotation on the distribution of DM and baryonic matter (B…

The Effect of a Self-bound Equation of State on the Structure of Rotating Compact Stars

Andreas Konstantinou

This paper investigates how a self bound equation of state (EOS), which describes strange quark stars, affects the rotational properties of compact stars, focusing on deviations fr…

Rotating Proto-Neutron Stars Admixed with Mirror Dark Matter: A two fluid approach

Adamu Issifu, Andreas Konstantinou, Prashant Thakur +1

This work investigates the impact of mirror dark matter (DM) on the global properties of rotating neutron stars (NSs) across evolutionary stages, from hot, lepton-rich protoneutron…
