Starspots as the origin of ultrafast drifting radio bursts from an active M dwarf
Jiale Zhang, Hui Tian, Stefano Bellotti +16
Detecting coherent radio bursts from nearby M dwarfs provides opportunities for exploring their magnetic activity and interaction with orbiting exoplanets. However, it remains unce…
Seismic test of the mass-radius relationship of hydrogen-atmospheric white dwarf stars
Tianqi Cang, Jiayi Zhang, Jian-Ning Fu +2
The pulsation of white dwarfs provides crucial information on stellar parameters for understanding the atmosphere and interior structure of these stars. In this study, we present a…
Phase II of the LAMOST-Kepler/K2 Survey. II. Time Domain of Medium-resolution Spectroscopic Observations from 2018 to 2023
Mingfeng Qin, Jian-Ning Fu, Weikai Zong +11
The LAMOST-Kepler/K2 Medium-Resolution Spectroscopic Survey (LK-MRS) conducted time-domain medium-resolution spectroscopic observations of 20 LAMOST plates in the Kepler and K2 fie…
Inactive longitude and superflare in the active single-lined pre-main sequence binary V2279 Cyg
Xueying Hu, Tianqi Cang, Jian-Ning Fu +7
Young, solar-like stars in the pre-main sequence (PMS) stage exhibit vigorous magnetic activity that significantly influences their circumstellar environments and the processes of…
Magnetic field of the roAp star KIC~10685175: observations versus theory
Fangfei Shi, Huawei Zhang, Swetlana Hubrig +5
KIC 10685175 is a roAp star whose polar magnetic field is predicted to be 6 kG through a non-adiabatic axisymmetric pulsation theoretical model. In this work, we aim to measure the…
