Energy Sources and Light Curves of Macronovae
Shota Kisaka, Kunihito Ioka, Hajime Takami
A macronova (kilonova) was discovered with a short gamma-ray burst, GRB 130603B, which is widely believed to be powered by the radioactivity of -process elements synthesized in…
Magnetic field configurations of a magnetar throughout its interior and exterior -- core, crust and magnetosphere
Kotaro Fujisawa, Shota Kisaka
We obtained the magnetic field configurations, including both poloidal and toroidal components, throughout the interior and exterior of magnetars using a realistic equation of stat…
Synchrotron X-ray emission from old pulsars
Shota Kisaka, Shuta J. Tanaka
We study the synchrotron radiation as the observed non-thermal X-ray emission from old pulsars (Myr) to investigate the particle acceleration in their magnetospheres.…
The Evolution of High Temperature Plasma in Magnetar Magnetospheres and its Implications for Giant Flares
Makoto Takamoto, Shota Kisaka, Takeru Suzuki +1
In this paper we propose a new mechanism describing the initial spike of giant flares in the framework of the starquake model. We investigate the evolution of a plasma on a closed…
