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…
Re-examining Super-Nyquist Frequencies of 68 Scuti Stars Utilizing the Kepler Long Cadence Photometry
Zilu Yang, Jianning Fu, Xuan Wang +2
The high-precision and long-duration photometry provided by the mission has greatly advanced frequency analyses of a large number of pulsating stars, a fundamental step in…
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…
Pulsation Properties of Blazhko and Non-Blazhko RRab Stars
Peng Zong, Jian-Ning Fu, Jie Su +8
In this study, we conduct a comparative analysis of the properties of Blazhko and non-Blazhko RRab stars. We identified 1054 non-Blazhko and 785 Blazhko RRab stars in the photometr…
