Asymmetric emissions of neutrinos in the cooling of rotating proto-neutron stars
Laura Barrio, Kotaro Fujisawa, Ryuichiro Akaho +2
We evaluate global asymmetry in the luminosities of neutrinos emitted from rapidly-rotating proto-neutron stars (PNS's). We build axisymmetric models of PNS's in mechanical equilib…
The optically thick rotating magnetic wind from a massive white dwarf merger product -- II. axisymmetric magnetohydrodynamic simulations
Yici Zhong, Kazumi Kashiyama, Shinsuke Takasao +2
We numerically construct a series of axisymmetric rotating magnetic wind solutions, aiming at exploring the observation properties of massive white dwarf (WD) merger remnants with…
Evolutionary deformation toward the elastic limit by a magnetic field confined in the neutron--star crust
Yasufumi Kojima, Shota Kisaka, Kotaro Fujisawa
Occasional energetic outbursts and anomalous X-ray luminosities are expected to be powered by the strong magnetic field in a neutron star. For a very strong magnetic field, elastic…
Strong toroidal magnetic fields sustained by the elastic crust in a neutron star
Kotaro Fujisawa, Yasufumi Kojima, Shota Kisaka
We investigate new solutions for magnetized neutron stars with a barotropic core in magnetohydrodynamic (MHD) equilibrium and a magneto-elastic crust, which was neglected by previo…
Self-Similar solution of rotating eruptive outflows on its equatorial plane
Takatoshi Ko, Kotaro Fujisawa, Toshikazu Shigeyama
We construct axisymmetric self-similar solutions of transonic outflows emanating from a point source including the effect of the rotation. The solutions are constructed exclusively…
Magnetically confined mountains on accreting neutron stars with multipole magnetic fields
Kotaro Fujisawa, Shota Kisaka, Yasufumi Kojima
Magnetically confined mountains on accreting neutron stars are candidates for producing continuous gravitational waves. We formulate a magnetically confined mountain on a neutron s…
