Duality of zero mean curvature surfaces in the Lorentzian Heisenberg group
Sai Rasmi Ranjan Mohanty, Priyank Vasu
We study a transformation surface associated with a zero mean curvature surface in the three-dimensional Heisenberg group with respect to two left-invariant semi-Riemannian metrics…
Astrophysical constraints on neutron star -modes with a nonparametric equation of state representation
Sailesh Ranjan Mohanty, Utkarsh Mali, H. C. Das +2
We constrain the fundamental-mode (-mode) oscillation frequencies of nonrotating neutron stars using a phenomenological Gaussian process model for the unknown dense-matter equat…
Singularities on maxfaces constructed by node-opening
Hao Chen, Anu Dhochak, Pradip Kumar +1
The node-opening technique, originally designed for constructing minimal surfaces, is adapted to construct a rich variety of new maxfaces of high genus that are embedded outside a…
Unstable Anisotropic Neutron Stars: Probing the Limits of Gravitational Collapse
S. R. Mohanty, Sayantan Ghosh, Bharat Kumar
Neutron stars (NSs) are incredibly versatile for studying various important aspects of high-energy and compact-object physics. These celestial objects contain extreme matter at inc…
