Two high-amplitude Scuti- Doradus hybrids constrained by the radial fundamental p and equally spaced g modes
Xinghao Chen, Xiaobin Zhang, Yan Li +1
Based on 2-minute cadence TESS data, we investigate pulsations of TIC 65138566 and TIC 139729335 and discover them to be two new HADS stars with equally spaced g modes. We recogniz…
A Spectroscopic Modelling Method for the Detached Eclipsing Binaries to Derive Atmospheric Parameters
Xiang-Lei Chen, A-Li Luo, Jian-Jun Chen +5
Based on luminosity contributions, we develop a spectroscopic modelling method to derive atmospheric parameters of component stars in binary systems. The method is designed for tho…
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…
TYC~2990-127-1: an Algol-type SB2 binary system of subgiant and red giant with a probable ongoing mass-transfer
Mikhail Kovalev, Zhenwei Li, Xiaobin Zhang +3
We present a study of the spectroscopic binary TYC 2990-127-1 from the LAMOST survey. We use full-spectrum fitting to derive radial velocities and spectral parameters. The high mas…
The Spectroscopic Binaries from LAMOST Medium-Resolution Survey (MRS). I. Searching for Double-lined Spectroscopic Binaries (SB2s) with Convolutional Neural Network
Bo Zhang, Ying-Jie Jing, Fan Yang +13
We developed a convolutional neural network (CNN) model to distinguish the double-lined spectroscopic binaries (SB2s) from others based on single exposure medium-resolution spectra…
OO Dra: an Algol-type binary formed through an extremely helium-poor mass accretion revealed by asteroseismology
Xinghao Chen, Xiaobin Zhang, Yan Li +4
Based on the two-minutes TESS data, we analyzed intrinsic oscillations of the primary component and identified seven confident independent Scuti frequencies (, , $f_3…
KIC 10736223: An Algol-type eclipsing binary just undergone the rapid mass-transfer stage
Xinghao Chen, Xiaobin Zhang, Yan Li +5
This paper reports the discovery of an Algol system KIC 10736223 that just past the rapid mass transfer stage. From the light curve and radial-velocity modelling we find KIC 107362…
Exploring the convective core of the hybrid Scuti- Doradus star CoRoT 100866999 with asteroseismology
Xinghao Chen, Yan Li, Xiaobin Zhang
We computed a grid of theoretical models to fit the Scuti frequencies of CoRoT 100866999 detected earlier from the CoRoT timeserials. The pulsating primary star is determined t…
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…
V1224 Cas - an EL CVn-type Eclipsing Binary Consisting of a Helium White Dwarf Precursor and a Delta Scuti Pulsator
Kun Wang, Changqing Luo, Xiaobin Zhang +3
We report the discovery of a new eclipsing EL CVn-type binary, consisting of a Sct-type pulsator and a thermally bloated low-mass pre-He white dwarf (WD). Spectroscopy and time…
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…
Physical parameter study of eight W Ursae Majoris-type contact binaries in NGC 188
Xiaodian Chen, Licai Deng, Richard de Grijs +10
We used the newly commissioned 50 cm Binocular Network (50BiN) telescope at Qinghai Station of Purple Mountain Observatory (Chinese Academy of Sciences) to observe the old open clu…
White-Light Flares on Close Binaries Observed with Kepler
Qing Gao, Yu Xin, Ji-Feng Liu +2
Based on Kepler data, we present the results of a search for white-light flares on 1049 close binaries. We identify 234 flare binaries, on which 6818 flares are detected. We compar…
