Precise parameter determination of the open cluster NGC 1647 via asteroseismology of p-mode pulsators
Mingfeng Qin, Jian-Ning Fu, Weikai Zong +4
Asteroseismology of member pulsators provides a robust physical constraint on cluster parameters by linking internal stellar structures to the global properties of the host cluster…
Measuring the magnetic fields in the chromospheres of low-mass stars
Tianqi Cang, Pascal Petit, Jean-François Donati +11
Magnetic fields in the upper atmospheres of solar-like stars are believed to provide an enormous amount of energy to power the hot coronae and drive large-scale eruptions that coul…
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…
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…
