Based on the Ni’s solution of Einstein Field Equations (EFE) we discuss the possibility of formation of a new type Neutron Star in which case the maximum density appears at a distance far from its center ( not at the center for normal neutron star case). As the inner core of such...
The discovery of gravitational waves (GW) from the coalescence binary system reduces the mass-gap to (2.6 – 5) M⊙ . Hypothetical stars such as the super-Chandrasekhar mass white dwarf, quark star, boson star, electro weak star, grav-star, dark matter star , supermassive neutron s...
We investigate the possible effect of an ultra-strong magnetic field on the core matter, in particular quark matter inside a massive rotating neutron star. Based on the discovery “Evidence of quark matter cores in massive Neutron Stars” by Annala et al. our main motivation is to...
The “Triaxial Star” was first proposed by S. Chandrasekhar in 1969, but to date it has not detected. The Cosmic Baby, i.e., SwiftJ1818.0-1607, is the youngest magnetar. It’s characteristic age is ~300 years, with a superfast spin period ~ 1.36s and a strong surface dipole magneti...
Taking into account three facts — (i) the ambipolar diffusion in Neutron Star core is expected to be the dominant mode of field decay in the early evolution of magnetar ( i.e as long as the ages much less than ~ 104 years), (ii) magnetar field decay is negligible as long as the c...
