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…
Missing pairs in open cluster catalogs
Qingshun Hu, Yufei Cai, Caroline Soubiran +4
Open clusters (OCs) in our Galaxy can be found in pairs, possibly forming physical binaries, or in groups. These objects offer unique insights into the process of star formation an…
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…
The morphological stability of open clusters: a new 2D perspective
Yuting Li, Qingshun Hu, Yufei Cai +3
Open clusters (OCs) usually evolve gradually as the number of their members changes, which can be manifested in their morphological characteristics. We aim to investigate the morph…
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…
Asteroseismology of the High-amplitude Scuti Star EH Librae
Xiran Xie, Jianning Fu, Gang Meng +7
A subclass of intermediate mass variables Scuti stars, known as High-amplitude Scuti (HADS) stars, exhibits pronounced radial pulsations. We used ground- and space-based ob…
An In-depth Investigation of the Primordial Cluster Pair ASCC 19 and ASCC 21
Qingshun Hu, Yuting Li, Mingfeng Qin +4
Utilizing \texttt{Gaia} data from the literature, we report a new young (8.9~Myr) cluster pair, ASCC~19 and ASCC~21, located near the Orion star-forming complex. The clusters…
Cluster aggregates surrounding Pismis 5 in the Vela Molecular Ridge
Ming Feng Qin, Yu Zhang, Jinzhong Liu +5
Context. In the Gaia era, the precision of astrometric data is unprecedented. High-quality data make it easier to find more cluster aggregates and support further confirmation of t…
A detection of the layered structure of nearby open clusters
Qingshun Hu, Yu Zhang, Ali Esamdin +2
We applied the newly developed rose diagram overlay method to detect the layered structure of 88 nearby open clusters (500~pc) on the three projections after the distance cor…
A Low-speed Intruder Star in Hyades: A Temporary Residence
Qingshun Hu, Yu Zhang, Ali Esamdin +4
We hereby report a low-speed (about~21~km~s with respect to the Sun) intruder member in the Hyades cluster based on the data in the literature. The results show that…
