The solar-like latitudinal distribution of flaring activities revealed by TESS, APOGEE and GALAH
Huiqin Yang, Shuai Liu, Yang Huang +2
Flare flux reflect contribution from active regions rather than the whole hemisphere of a star. Unlike the amplitude of light-curves caused by starspots, the flare detection is ind…
Evaluating the chromospheric structure model of AD Leo using RH1.5D and magnetic field data
Shuai Liu, Jianrong Shi, Huigang Wei +4
Context. The interplay between surface magnetic topology and chromospheric heating in active M dwarfs remains poorly constrained, limiting our understanding of their magnetic cycle…
LEIA discovery of the longest-lasting and most energetic stellar X-ray flare ever detected
Xuan Mao, He-Yang Liu, Song Wang +40
The Lobster Eye Imager for Astronomy (LEIA) detected a new X-ray transient on 2022 November 7, identified as a superflare event occurring on a nearby K-type giant star HD 251108. T…
Flaring Activities of Fast Rotating Stars have Solar-like Latitudinal Distribution
Huiqin Yang, Xin Cheng, Jifeng Liu +6
The dynamo theory has always been one of the biggest mysteries in stellar physics. One key reason for its uncertainty is poor knowledge of the dynamo process on stars except the Su…
Chromospheric modeling of the active M3V star G 80-21 with RH1.5D
Shuai Liu, Huigang Wei, Jianrong Shi +4
This study investigates the active regions of the M3.0V star G 80-21 using the observed data from the CARMENES project with synthetic spectra generated by the RH1.5D radiative tran…
