Statistical evidence for linear combination frequencies in γ Doradus stars being nonlinear resonant modes
Yanqi Mo, Weikai Zong, Xuan Wang +4
The quest for the origin of linear combination frequencies in pulsating stars is critical for mode identification and subsequent seismic modeling. Hybrid γ Doradus (Dor) stars prov…
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…
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…
Asteroseismological analysis of the non-Blazhko RRab star EPIC~248846335 in LAMOST -- Kepler K2 project
Peng Zong, Jian-Ning Fu, Jie Su +9
We conduct an asteroseismological analysis on the non-Blazhko ab-type RR Lyrae star EPIC 248846335 employing the Radial Stellar Pulsations (RSP) module of the Modules for Experimen…
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…
Amplitude and frequency variations in PG~0101+039 from K2 photometry -- A pulsating hot B subdwarf star in an unsynchronized binary system
Xiao-Yu Ma, Weikai Zong, Jian-Ning Fu +3
K2 photometry is suitable for the exploitation of mode variability on short timescales in hot B subdwarf stars, which is important to constrain nonlinear quantities addressed by th…
