Distinct Signatures of the Nature of Phase Transition in Binary Neutron Star Mergers
Sagnik Chatterjee, Shamim Haque, Kamal Krishna Nath +2
Binary neutron-star mergers offer crucial insights into the matter properties of neutron stars. We present the possible imprints in the gravitational wave signal from the nature of…

Dynamical response of twin stars to perturbations
Shamim Haque, Luciano Rezzolla, Ritam Mallick
If a strong first-order phase transition takes place at sufficiently high rest-mass densities in the equation of state (EOS) modelling compact stars, a new branch will appear in th…

Investigating Twin Star Equation of States in Light of Recent Astrophysical Observations
Shamim Haque, Atharva Shinde, Asim Kumar Saha +2
Twin stars are predicted to exist in nature if the hadron-to-quark phase transition is strong enough to form a new branch of hybrid stars, separated from the branch of neutron star…
