Hybrid stars among mass gap objects are excluded by twin stars at
Alexander Ayriyan, David Blaschke, Marcin Dubaj +2
The paper examines whether compact objects in the 2.5–5 M⊙ mass gap could be hybrid stars, using a generic hybrid star equation of state with a first-order deconfinement transition…
Observational Probes of the Neutron Star Equation of State with Hyperons, Bosonic Dark Matter, and Quark Matter
Mahboubeh Shahrbaf, Davood Rafiei Karkevandi, Alexander Ayriyan +1
Context. The presence of dark matter in neutron stars is of growing interest due to its potential impact on the structure and observable properties of these objects. Among the vari…
Bayesian inference favors quark matter in neutron star interiors
Alexander Ayriyan, Oleksii Ivanytskyi, David Blaschke
We perform a physics-informed Bayesian analyses of the equation of state of hybrid neutron stars that incorporates color-flavor-locked quark matter modeled by a three-flavor non-lo…
Bayesian analysis of hybrid neutron star EOS constraints within an instantaneous nonlocal chiral quark matter model
Alexander Ayriyan, David Blaschke, Juan Pablo Carlomagno +2
We present a physics-informed Bayesian analysis of equation of state constraints using observational data for masses, radii and tidal deformability of pulsars and a generic class o…
