Universality of dual mass-scaled fundamental modes in two-fluid neutron stars with mirror dark matter
Hajime Sotani, Ankit Kumar
Universal relations provide a particularly useful way to extract physical information from neutron star observables in the presence of various uncertainties by reducing the depende…

Slowly Rotating Two-Fluid Neutron Stars: Coupled Frame-Dragging, Inertia Splitting, and Universal Relations
Ankit Kumar, Hajime Sotani
We develop a fully relativistic framework to study the rotational response of gravitationally coupled two-fluid neutron stars within the slow-rotation approximation. Treating the t…
