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…
A new code for low-resolution spectral identification of white dwarf binary candidates
Genghao Liu, Baitian Tang, Liangliang Ren +7
Close white dwarf binaries (CWDBs) are considered to be progenitors of several exotic astronomical phenomena (e.g., type Ia supernovae, cataclysmic variables). These violent events…
Stellar atmospheric parameters of 11,000 RR Lyrae stars from LAMOST Spectra
Jiangtao Wang, Jianrong Shi, Jianning Fu +2
Accurate determination of the stellar atmospheric parameters of RR Lyrae stars (RRLs) requires short individual exposures of the spectra to mitigate pulsation effects. We present i…
Flares hunting in hot subdwarf and white dwarf stars from Cycles 1-5 of TESS photometry
Keyu Xing, Weikai Zong, Roberto Silvotti +9
Stellar flares are critical phenomena on stellar surfaces, which are closely tied to stellar magnetism. While extensively studied in main-sequence (MS) stars, their occurrence in e…
Variable white dwarfs in TMTS: Asteroseismological analysis of a ZZ Ceti star, TMTS J17184064+2524314
Jincheng Guo, Yanhui Chen, Yonghui Yang +24
The Tsinghua University-Ma Huateng Telescope for Survey (TMTS) has been constantly monitoring the northern sky since 2020 in search of rapidly variable stars. To find variable whit…
TESS Cycle 2 observations of roAp stars with 2-min cadence data
D. L. Holdsworth, M. S. Cunha, M. Lares-Martiz +46
We present the results of a systematic search of the Transiting Exoplanet Survey Satellite (TESS) 2-min cadence data for new rapidly oscillating Ap (roAp) stars observed during the…
Mode identification in three pulsating hot subdwarfs observed with TESS satellite
S. K. Sahoo, A. S. Baran, U. Heber +12
We report on the detection of pulsations of three pulsating subdwarf B stars observed by the TESS satellite and our results of mode identification in these stars based on an asympt…
