Probing Red Giant Interiors with G-Dominated Mixed Modes I: The Cases of KIC 9145955, KIC 9970396, KIC 9882316 and KIC 11968334
Xinyi Zhang, Tanda Li, Jianxing Chen +4
We perform a detailed asteroseismic analysis of four red giants observed by Kepler: KIC 9145955, KIC 9970396, KIC 9882316, and KIC 11968334. Our study is based on individual oscill…
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…
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…
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…
Can small-scale magnetic fields be the major cause for the near-surface effect of the solar p-mode frequencies?
Yan Li, Qian-sheng Zhang, Tao Wu +5
Small-scale magnetic fields are not only the fundamental element of the solar magnetism, but also closely related to the structure of the solar atmosphere. The observations have sh…
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…
Asteroseismology of the pre-main-sequence Scuti pulsator IP Persei
Xinghao Chen, Yan Li
A grid of theoretical models are computed to fit the 9 oscillation modes of IP Per detected earlier from a multi-site ground-based campaign. Fitting results show that there are two…
Overshooting in the core helium burning stage of a star using the - model
Yan Li, Xing-hao Chen, Hai-liang Chen
Overshooting and semiconvection are among the most uncertainties in the evolution of massive stars. Complete mixing over a certain distance beyond the convective boundary (Stothers…
Determining the evolutionary stage of the delta Scuti star HIP 80088 with asteroseismology
Xinghao Chen, Yan Li
We have computed a grid of theoretical models to fit the twelve oscillation modes of HIP 80088 observed by K2. HIP 80088 is determined to be a pre-main sequence star, in which CN c…
Convective overshooting in sdB stars using the - model
Yan Li, Xing-hao Chen, He-ran Xiong +3
Mixing in the convective core is quite uncertain in core helium burning stars. In order to explore the overshooting mixing beyond the convective core, we incorporated the - p…
Rotational splitting and asteroseismic modelling of the delta Scuti star EE Camelopardalis
Xinghao Chen, Yan Li
According to the rotational splitting law of g modes, the frequency spectra of EE Cam can be disentangled only with oscillation modes of = 0, 1, and 2. Fifteen sets of rotat…
Exploring the helium core of the delta Scuti star CoRoT 102749568 with asteroseismology
Xinghao Chen, Yan Li, Guifang Lin +2
Based on regularities in rotational splittings, we seek possible multiplets for the observed frequencies of CoRoT 102749568. Twenty-one sets of multiplets are identified, including…
