Empirical colour--effective temperature relations in the SDSS system from IRFM temperatures of GALAH and APOGEE stars
Zenghua Zhou, Luca Casagrande, Xiaobin Zhang +5
Reliable estimates of stellar effective temperature () are fundamental to stellar population studies and Galactic astrophysics. However, the majority of stars ob…
A Search for High Frequency Oscillations in TESS Cycle 7
Guanda Huang, Xiaodian Chen, Shu Wang +2
High-quality, short-cadence photometry from TESS enables the detection of rapid oscillators with unprecedented sensitivity. In this work, we conduct a homogeneous search for high-f…
A New Algol-type Binary with an Accretion disk
Tongyu He, Jiao Li, Xiaobin Zhang +10
We present a comprehensive photometric and spectroscopic analysis of the Algol-type binary \textit{Gaia} DR3 1892576067672499328. We identified the system as a spectroscopic binary…
Exploring the convective core of the high-amplitude Scuti star TIC 120857354 with asteroseismology
Xinghao Chen, Xaiobin Zhang, Yan Li
Based on 2-minute cadence TESS data, 20 confident independent frequencies were identified for the star TIC 120857354. The Kolmogorov-Smirnov test reveals a rotational splitting of…
