Multi-frequency radio observations of the radio-loud magnetar XTE J1810-197
Sujin Eie, Toshio Terasawa, Takuya Akahori +11
We report on the multi-frequency multi-epoch radio observations of the magnetar, XTE J1810-197, which exhibited a radio outburst from December 2018 after its 10-year quiescent peri…
A month of monitoring the new magnetar Swift J1555.2-5402 during an X-ray outburst
Teruaki Enoto, Mason Ng, Chin-ping Hu +23
The soft gamma-ray repeater Swift J1555.2-5402 was discovered by means of a 12-ms duration short burst detected with Swift BAT on 2021 June 3. Then 1.6 hours after the first burst…
The response of black hole spark gaps to external changes: A production mechanism of rapid TeV flares?
Shota Kisaka, Amir Levinson, Kenji Toma +1
We study the response of a starved Kerr black hole magnetosphere to abrupt changes in the intensity of disk emission and in the global magnetospheric current, by means of 1D genera…
On the Angular Momentum Extraction from the Rotation Powered Pulsars
Shinpei Shibata, Shota Kisaka
The rotation powered pulsar loses angular momentum at a rate of the rotation power divided by the angular velocity . This means that the length of the lever arm of the angular…
Magneto-elastic equilibrium of a neutron-star crust
Yasufumi Kojima, Shota Kisaka, Kotaro Fujisawa
We examine the equilibrium of a magnetized neutron-star-crust. We calculate axially symmetric models in which an elastic force balances solenoidal motion driven by a Lorentz force.…
Enhanced X-ray Emission Coinciding with Giant Radio Pulses from the Crab Pulsar
Teruaki Enoto, Toshio Terasawa, Shota Kisaka +34
Giant radio pulses (GRPs) are sporadic bursts emitted by some pulsars, lasting a few microseconds. GRPs are hundreds to thousands of times brighter than regular pulses from these s…
