Multi-mode delta Sct stars from the Zwicky Transient Facility Survey
Qi Jia, Xiaodian Chen, Shu Wang +3
We obtain the largest catalog of multi-mode Sct stars in the northern sky to date using the Zwicky Transient Facility (ZTF) Data Release 20 (DR20). The catalog includes 2254 ob…
An 18.9-minute Blue Large-Amplitude Pulsator Crossing the 'Hertzsprung Gap' of Hot Subdwarfs
Jie Lin, Chengyuan Wu, Xiaofeng Wang +28
Blue large-amplitude pulsators (BLAPs) represent a new and rare class of hot pulsating stars with unusually large amplitudes and short periods. Up to now, only 24 confirmed BLAPs h…
Unveiling hidden stellar aggregates in the Milky Way: 1656 new star clusters found in Gaia EDR3
Zhihong He, Xiaochen Liu, Yangping Luo +2
We report 1,656 new star clusters found in the Galactic disk (|b|<20 degrees) beyond 1.2 kpc, using Gaia EDR3 data. Based on an unsupervised machine learning algorithm, DBSCAN, and…
A Roche Lobe-filling hot Subdwarf and White Dwarf Binary: possible detection of an ejected common envelope
Jiangdan Li, Christopher A. Onken, Christian Wolf +12
Binaries consisting of a hot subdwarf star and an accreting white dwarf (WD) are sources of gravitational wave radiation at low frequencies and possible progenitors of type Ia supe…
Extremely low-mass white dwarf stars observed in Gaia DR2 and LAMOST DR8
Kun Wang, Péter Németh, Yangping Luo +3
We present the first results from our ongoing project to study extremely low mass (ELM) white dwarfs (WDs) ( 0.3$M_{\sun}$) with the Large Sky Area Multi-Object Fibre Spe…
Kinematic-Chemical analysis and Time tagging for the Diagonal Ridge Structure of the Galactic Outer Disk with LAMOST Red Giant Branch Stars
Peng Yang, Hai-Feng Wang, Zhi-Quan Luo +2
We investigate the kinematic-chemical distribution of Red Giant Branch (RGB) stars from the LAMOST survey crossed matched with Gaia DR2 proper motions, and present time tagging for…
Mass and Age determination of the LAMOST data with different Machine Learning methods
Qi-Da Li, Hai-Feng Wang, Yang-Ping Luo +3
We present a catalog of 948,216 stars with mass label and a catalog of 163,105 red clump (RC) stars with mass and age labels simultaneously. The training dataset is cross matched f…
Physical Properties of 29 sdB+dM Eclipsing Binaries in Zwicky Transient Facility
Min Dai, Xiaodian Chen, Kun Wang +3
The development of large-scale time-domain surveys provides an opportunity to study the physical properties as well as the evolutionary scenario of B-type subdwarfs (sdB) and M-typ…
Hot subdwarf Atmospheric parameters, Kinematics, and Origins -- Based on 1587 hot subdwarf stars observed in Gaia DR2 and LAMOST DR7
Yangping Luo, Peter Nemeth, Kun Wang +2
Based on the Gaia DR2 catalogue of hot subdwarf star candidates, we identified 1587 hot subdwarf stars with spectra in LAMOST DR7. We present atmospheric parameters for these stars…
Hot Subdwarf Stars Identified in Gaia DR2 with Spectra of LAMOST DR6 and DR7. II. Kinematics
Yangping Luo, Peter Nemeth, Qida Li
Combining the LAMOST radial velocities with Gaia parallaxes and proper motions, we presented 3D Galactic space motions and the orbits of 182 single-lined hot subdwarf stars. These…
Hot subdwarf stars observed in Gaia DR2 and LAMOST DR5
Yangping Luo, Péter Németh, Licai Deng +1
Combing Gaia DR2 with LAMOST DR5, we spectroscopically identified 924 hot subdwarf stars, among which 32 stars exhibit strong double-lined composite spectra. We measured the effect…
Frequent flare events on the short-period M-type eclipsing binary BX Tri
ChangQing Luo, XiaoBin. Zhang, Kun Wang +8
We present long-term, multi-color photometric monitoring and spectroscopic observations of the short-period M-type eclipsing binary BX Tri. Six flare events were recorded in 4 year…
Misclassified B stars in the Kepler field
Chunguang Zhang, Chao Liu, Yue Wu +7
Stellar fundamental parameters are important in the asteroseismic study of Kepler light curves. However, the most used estimates in the Kepler Input Catalog (KIC) are not accurate…
Hot Subdwarf Stars Observed in LAMOST DR1 - Atmospheric parameters from single-lined spectra
Yangping Luo, Peter Nemeth, Chao Liu +2
We present a catalog of 166 spectroscopically identified hot subdwarf stars from LAMOST DR1, 44 of which show the characteristics of cool companions in their optical spectra. Atmos…
Photometric study and period analysis of the contact binary XZ Leonis
