Mass--radius relations, surface redshift, and echo time of neutron-star--wormhole system with chaotic magnetic field and anisotropic matter
Muhammad Lawrence Pattersons, Freddy Permana Zen, Hadyan Luthfan Prihadi +1
In this paper, we formulate neutron-star--wormhole (NSWH) systems supported by two scalar fields, allowing for both chaotic magnetic field and pressure anisotropy of the neutron fl…
Impact of Rastall gravity on hydrostatic mass of galaxy clusters
M. Lawrence Pattersons, Feri Apryandi, Freddy P. Zen
Galaxy clusters are the largest virialized structures in the Universe and are predominantly dominated by dark matter. The hydrostatic mass and the mass obtained from gravitational…
Mass-radius relation, moment of inertia, and tidal love numbers of anisotropic neutron stars in f (R,T) gravity
Yusmantoro Yusmantoro, Freddy Permana Zen, Muhammad Lawrence Pattersons
The mass-radius relation, moment of inertia, and tidal love numbers of anisotropic neutron stars (NSs) have been investigated in gravity by imposing two equations of state…
Rotational mass of anisotropic neutron stars within Rastall gravity
M. Lawrence Pattersons, Freddy P. Zen, Hadyan L. Prihadi +1
Due to rotation, the mass correction of neutron stars arises and causes the rotational mass to be larger than the static mass. In this work, we extend the formulation of the rotati…
Hydrostatic mass of galaxy clusters within some theories of gravity
Feri Apryandi, M. Lawrence Pattersons
The mass of galaxy clusters (GCs) can be determined by calculating the hydrostatic equilibrium equation. In this work, we derive the hydrostatic mass of GCs within Eddington-inspir…
Kepler frequency and moment of inertia of rotating neutron stars with chaotic magnetic field
Muhammad Lawrence Pattersons, Freddy Permana Zen
Rotating neutron stars (NSs) are crucial objects of study, as our understanding of them relies significantly on observational data from these rotating stars. Observations suggest t…
