Surface gravity wave on a neutron star ocean trapped around a magnetic pole

S. Yoshida

A warm neutron star is expected to have a fluid "ocean" of heavy elements at its outermost part of the outer crust. As is on the terrestrial ocean, the neutron star ocean also has surface gravity waves. Around a magnetic pole of …

Bifurcation and stability of uniformly rotating homogeneous ellipsoids surrounded by a massive thin ring

S. Yoshida

Abstract We examine the effects of a massive concentric ring around a spheroid or an ellipsoid with uniform density and uniform rotation. Equilibrium sequences of axisymmetric Maclaurin-like spheroid and triaxial Jacobi-like ellipsoids are obtained. Due to the gravitational field of the ring, …

A numerical modelling of rotating substellar objects up to mass-shedding limits

S. Yoshida

ABSTRACT Rotation may affect the occurrence of sustainable hydrogen burning in very low-mass stellar objects by the introduction of centrifugal force to the hydrostatic balance as well as by the appearance of rotational break-up of the objects (mass-shedding limit) for rapidly rotating …

Fitting Rotational Frequency of Polytropes as a Function of their Oblateness

S. Yoshida

Abstract Giving a simple functional relationship between the rotational frequency and the centrifugal deformation for compressible stellar models is useful both in observational and theoretical astrophysics. Here I present simple Padé approximants for the rotational frequency of polytropic stars (index N = …

Assessment of the Roche and the Darwin–Radau Approximations for Rotating Astrophysical Objects

S. Yoshida

Abstract Assessment of two of the frequently used approximations for rotating astrophysical objects, the Roche and the Darwin–Radau approximations, is performed by comparing the rotational frequencies computed by these approximations with those of self-consistent numerical hydrostatic solutions. Overall, the Darwin–Radau approximation performs …

Near-Chandrasekhar-mass Type Ia Supernovae from the Double-degenerate Channel

Sudarshan Neopane, Khanak Bhargava, Robert Fisher, Mckenzie G. Ferrari et autres

Abstract Recent observational evidence has demonstrated that white dwarf (WD) mergers are a highly efficient mechanism for mass accretion onto WDs in the galaxy. In this paper, we show that WD mergers naturally produce highly magnetized, uniformly rotating WDs, including a substantial …
