Possible measurement of Quintessence and density parameter using strong gravitational lensing events
Toshifumi Futamase, Shijun Yoshida
We propose a possible measurement of the time variability of the vacuum energy using strong gravitational lensing events. As an example we take an Einstein cross lens HST 14176+522…
R-mode oscillations of rapidly rotating Newtonian stars - A new numerical scheme and its application to the spin evolution of neutron stars
Shigeyuki Karino, Shin'ichirou Yoshida, Shijun Yoshida +1
We have developed a new numerical scheme to solve r-mode oscillations of {\it rapidly rotating polytropic stars} in Newtonian gravity. In this scheme, Euler perturbations of the de…
R-modes of neutron stars with a solid crust
Shijun Yoshida, Umin Lee
We investigate the properties of -mode oscillations of a slowly rotating neutron star with a solid crust, by taking account of the effects of the Coriolis force. For the modal a…
Rotational modes of non-isentropic stars and the gravitational radiation driven instability
Shijun Yoshida, Umin Lee
We investigate the properties of r-mode and inertial mode of slowly rotating, non-isentropic, Newtonian stars, by taking account of the effects of the Coriolis force and the centri…
