Statistical evidence for linear combination frequencies in γ Doradus stars being nonlinear resonant modes

莫言起, Weikai Zong, Xuan Wang, Jian-Ning Fu et autres

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 provide a crucial test bed for such investigations due to their rich frequency content in both …

Identification and characterization of 15 265 super-Nyquist frequencies in 1309

莫言起, Weikai Zong, Xuan Wang, Simon Murphy et autres

The frequency of the pressure (p) mode in δ Scuti stars can exceed the Nyquist limit of Kepler long-cadence photometry. These “superNyquist frequencies” (SNFs) are observed as “reflected” peaks at lower frequencies, i.e., they are Nyquist aliases that pose a threat to …

Precise Parameter Determination of the Open Cluster NGC 1647 via Asteroseismology of p -mode Pulsators

Mingfeng Qin, Jian-Ning Fu, Weikai Zong, Tianqi Cang et autres

Abstract 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. However, the parameters of NGC 1647 remain poorly constrained due to limited investigation, a situation that …

Measuring the magnetic fields in the chromospheres of low-mass stars

Tianqi Cang, P. Petit, Hui Tian, Jian-Ning Fu et autres

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 could impact the habitability of planetary systems around these stars. However, these magnetic fields …

Planets Across Space and Time (PAST). VIII. Kinematic Characterization and Identification of Radial Velocity Variables for the LAMOST–Gaia–TESS Stars

Di-Chang Chen, Ji‐Wei Xie, Ji‐Lin Zhou, Haifeng Wang et autres

Abstract The Transiting Exoplanet Survey Satellite (TESS) has discovered over 6700 nearby exoplanet candidates using the transit method through its all-sky survey. Characterizing the kinematic properties and identifying variable stars for the TESS stellar sample is crucial for revealing the correlations between …
