A0538-66: A transient ultraluminous X-ray source with a relativistic outflow, 69ms pulsations, and anomalous optical activity
Lorenzo Ducci, Sandro Mereghetti, Ciro Pinto +8
A0538-66 is a peculiar Be/X-ray binary in the Large Magellanic Cloud, hosting the fastest spinning neutron star of its class (~69ms) and showing the brightest optical bursts of any…
Thermonuclear superburst of MAXI J1752457 observed with NinjaSat and MAXI
Amira Aoyama, Teruaki Enoto, Takuya Takahashi +17
An uncatalogued bright X-ray transient was detected with MAXI on November 9, 2024, named MAXI J1752457. The NinjaSat X-ray observatory promptly observed the source from November…
Optical Observations of the High Mass X-ray Binary MAXI J0709159/LY CMa
Megumi Shidatsu, Nobuyuki Kawai, Hiroyuki Maehara +12
We report on the optical spectroscopic monitoring of the X-ray transient MAXI J0709159 (identified as the Be star LY CMa) performed for about 1.5 months after the X-ray detectio…
X-Raying Neutral Density Disturbances in the Mesosphere and Lower Thermosphere induced by the 2022 Hunga-Tonga Volcano Eruption-Explosion
Satoru Katsuda, Hiroyuki Shinagawa, Hitoshi Fujiwara +14
We present X-ray observations of the upper atmospheric density disturbance caused by the explosive eruption of the Hunga Tonga-Hunga Ha'apai (HTHH) volcano on 15 January 2022. From…
Long-Term Density Trend in the Mesosphere and Lower Thermosphere from Occultations of the Crab Nebula with X-Ray Astronomy Satellites
Satoru Katsuda, Teruaki Enoto, Andrea N. Lommen +9
We present long-term density trends of the Earth's upper atmosphere at altitudes between 71 and 116 km, based on atmospheric occultations of the Crab Nebula observed with X-ray ast…
Discovery of a new supergiant fast X-ray transient MAXI J0709-159 associated with the Be star LY CMa
Mutsumi Sugizaki, Tatehiro Mihara, Kohei Kobayashi +10
We report on the discovery of a new supergiant fast X-ray transient (SFXT), MAXI J0709159, and its identification with LY CMa (also known as HD 54786). On 2022 January 25, a new…
