X-ray/H scaling relationships in stellar flares
Hiroki Kawai, Yohko Tsuboi, Wataru B. Iwakiri +5
We report on the results of our simultaneous observations of three large stellar flares with soft X-rays (SXRs) and an H emission line from two binary systems of RS CVn t…
Quantitative optical imaging method for surface acoustic waves using optical path modulation
Ryusuke Hisatomi, Kotaro Taga, Ryo Sasaki +3
A Rayleigh-type surface acoustic wave (SAW) is used in various fields as classical and quantum information carriers because of its surface localization, high electrical controllabi…
Optical polarimetric measurement of surface acoustic waves
Kotaro Taga, Ryusuke Hisatomi, Yuichi Ohnuma +4
Surface acoustic wave (SAW) is utilized in diverse fields ranging from physics, engineering, to biology, for transducing, sensing and processing various signals. Optical measuremen…
The RS CVn type star GT Mus shows most energetic X-ray flares throughout the 2010s
Ryo Sasaki, Yohko Tsuboi, Wataru Iwakiri +14
We report that the RS CVn-type star GT Mus (HR 4492, HD 101379 + HD 101380) was the most active star in the X-ray sky in the last decade in terms of the scale of recurrent energeti…
Optical and X-ray observations of stellar flares on an active M dwarf AD Leonis with Seimei Telescope, SCAT, NICER and OISTER
Kosuke Namekata, Hiroyuki Maehara, Ryo Sasaki +24
We report multi-wavelength monitoring observations of an M-dwarf flare star AD Leonis with Seimei Telescope (6150--7930 Å), SCAT (Spectroscopic Chuo-university Astronomical Telesco…
