Early deconfinement of asymptotically conformal color-superconducting quark matter in neutron stars
Oleksii Ivanytskyi, David Blaschke, Tobias Fischer +1
We present a relativistic density functional approach to color superconducting quark matter that mimics quark confinement by a fast growth of the quasiparticle selfenergy in the co…
Special point "trains" in the M-R diagram of hybrid stars
David Blaschke, Alexander Ayriyan, Mateusz Cierniak +3
We present a systematic investigation of the possible locations for the special point (SP), a unique feature of hybrid neutron stars in the mass-radius diagram. The study is perfor…
How does dark matter affect compact star properties and high density constraints of strongly interacting matter
Violetta Sagun, Edoardo Giangrandi, Oleksii Ivanytskyi +2
We study the impact of asymmetric bosonic dark matter on neutron star properties, including possible changes of tidal deformability, maximum mass, radius, and matter distribution i…
The effects of self-interacting bosonic dark matter on neutron star properties
Edoardo Giangrandi, Violetta Sagun, Oleksii Ivanytskyi +2
We propose a model of asymmetric bosonic dark matter (DM) with self-repulsion mediated by the vector field coupled to the complex scalar particles. By adopting the two-fluid formal…
Recovering the conformal limit of color superconducting quark matter within a confining density functional approach
Oleksii Ivanytskyi, David Blaschke
We generalize a recently proposed confining relativistic density-functional approach to the case of density dependent vector and diquark couplings. The particular behavior of these…
Early quark deconfinement in compact star astrophysics and heavy-ion collisions
Oleksii Ivanytskyi, David Blaschke, Tobias Fischer +1
Based on a recently developed relativistic density functional approach to color-superconducting quark matter and a novel quark-hadron transition construction which phenomenological…
