Evidence of non-Solar elemental composition in the clocked X-ray burster SRGA J144459.2604207
Akira Dohi, Nobuya Nishimura, Ryosuke Hirai +13
In February and March 2024, a series of many Type I X-ray bursts from the accreting neutron star SRGA J144459.2604207, which has been identified by multiple X-ray satellites, wi…
NinjaSat monitoring of Type-I X-ray bursts from the clocked burster SRGA J144459.2604207
Tomoshi Takeda, Toru Tamagawa, Teruaki Enoto +25
The CubeSat X-ray observatory NinjaSat was launched on 2023 November 11 and has provided opportunities for agile and flexible monitoring of bright X-ray sources. On 2024 February 2…
Gravitational wave asteroseismology of accreting neutron stars in a steady state
Hajime Sotani, Akira Dohi
An accreting neutron star is potentially the gravitational wave source. In this study, we examine the gravitational wave frequencies from such an object in the steady state, adopti…
Nuclear Burning in Accretion Flow of Helium-rich matter onto Compact Objects
Toshikazu Shigeyama, Akira Dohi
We investigate the impacts of nuclear burning on the spherically symmetric stationary accretion flow of helium-rich matter on to compact objects. We have already shown the existenc…
Big-Bang Nucleosynthesis on a bubble universe nucleated in Kerr-AdS Black Hole
Akira Dohi, Issei Koga, Kazushige Ueda
We present the Big-Bang Nucleosynthesis (BBN) simulation with a bubble universe scenario around a rotating black hole (BH) in Kerr-AdS spacetime to explain recently updated obs…
