Diversity in Evolutionary Status and Magnetic Activity among Solar-Type Twin Detached Eclipsing Binaries
Fang-Bin Meng, Li-Ying Zhu, Sheng-Bang Qian +9
We present a combined photometric and spectroscopic analysis of four detached eclipsing binaries (KIC 8957954, KIC 10593759, KIC 8302455, and TIC 207398432), all of which exhibit c…
HD 26172: an active solar-type subgiant in a close binary system
Fang-Bin Meng, Li-Ying Zhu, Sheng-Bang Qian +5
We present the first comprehensive photometric and spectroscopic analysis of the RS CVn system HD 26172, robustly determining the previously debated evolutionary state of its prima…
Observational Properties of Cephei Stars: 88 new samples discovered Based on TESS and Gaia Data
Xiang-dong Shi, Sheng-bang Qian, Li-ying Zhu +5
We present a systematic investigation of Cephei (BCEP) stars by integrating photometric data from the Transiting Exoplanet Survey Satellite (TESS) with astrometric parameters f…
Asteroseismology of HD 23734, HD 68703, and HD 73345 using K2-TESS Space-based Photometry and High-resolution Spectroscopy
Santosh Joshi, Athul Dileep, Eugene Semenko +14
In this paper, we present a comprehensive study of three stars, HD 23734, HD 68703, and HD 73345, which were previously observed as chemically peculiar candidates within the Nainit…
Investigating Pulsating Variables and Eclipsing Binaries in NGC 2126 using Ground and Space-based Photometry, Astrometry, Spectroscopy and Modeling
Athul Dileep, Santosh Joshi, Sneh Lata +12
Pulsating variables are prevalent in the classical δ Scuti instability strip of intermediate-age open star clusters. The cluster membership of these stars facilitates a comparative…
HD 34736: An intensely magnetised double-lined spectroscopic binary with rapidly-rotating chemically peculiar B-type components
E. Semenko, O. Kochukhov, Z. Mikulášek +21
We report the results of a comprehensive study of the spectroscopic binary (SB2) system HD 34736 hosting two chemically peculiar (CP) late B-type stars. Using new and archival obse…
Asteroseismology of the mild Am Sct star HD 118660 : TESS photometry and modelling
Mrinmoy Sarkar, Santosh Joshi, Marc-Antoine Dupret +9
We present the results of an asteroseismic study of HD 118660 (TIC 171729860), being a chemically peculiar (mild Am) star exhibiting Scuti ( Sct) pulsations. It is based on…
TESS Cycle 2 observations of roAp stars with 2-min cadence data
D. L. Holdsworth, M. S. Cunha, M. Lares-Martiz +46
We present the results of a systematic search of the Transiting Exoplanet Survey Satellite (TESS) 2-min cadence data for new rapidly oscillating Ap (roAp) stars observed during the…
TESS Cycle 1 observations of roAp stars with 2-min cadence data
D. L. Holdsworth, M. S. Cunha, D. W. Kurtz +41
We present the results of a systematic search for new rapidly oscillating Ap (roAp) stars using the 2-min cadence data collected by the Transiting Exoplanet Survey Satellite (TESS)…
Variable Stars
