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…
Varying core-envelope coupling efficiency identified from stellar rotation--activity relation
Henggeng Han, Song Wang, Huiqin Yang +5
Core-envelope coupling provides a reasonable explanation of the spin-down stalling of stars in open clusters, which was not predicted by classical gyrochronology. However, it remai…
LightCurve MoE: A Dynamic Sparse Routing Mixture-of-Experts Architecture for Efficient Stellar Light Curve Classification
Cunshi Wang, Yu Bai, Xinrui Song +6
The classification of stellar light curves has become a key task in modern time-domain astronomy, fueled by the rapid growth of data from large-scale surveys such as Kepler and TES…
Four ages of rotating stars in the rotation--activity relationship and gyrochronology
Huiqin Yang, Jifeng Liu, Roberto Soria +4
Gyrochronology and the rotation--activity relationship are standard techniques used to determine the evolution phase.The mismatch in the definition of the evolutionary phases has s…
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…
