Properties and Asteroseismological analysis of a new ZZ ceti discovered by TMTS
Jincheng Guo, Yanhui Chen, Xiaofeng Wang +24
Tsinghua university-Ma Huateng Telescope for Survey (TMTS) aims to discover rapidly evolving transients by monitoring the northern sky. The TMTS catalog is cross-matched with the w…
Asteroseismology of the DAV star L19-2
Yanhui Chen
L19-2 is a DAV star, which has been intermittently observed from 1976 to 2013. Five independent pulsation modes of 350\,s, 192\,s, 143\,s, 118\,s, and 113\,s are identified. The fi…
Asteroseismology of the DAV star R808
Yanhui Chen, Hong Shu
The DAV star R808 was observed by 13 different telescopes for more than 170 hours in April 2008 on the WET run XCOV26. 25 independent pulsation frequencies were identified by this…
Application of screened Coulomb potential in fitting DBV star PG 0112+104
Yanhui Chen
With 78.7 days of observations for PG 0112+104, a pulsating DB star, from Campaign 8 of 2 mission, Hermes et al. made a detailed mode identification. A reliable mode ident…
The rate of period change in DAV stars
Y. H. Chen, C. Y. Ding, W. W. Na +1
Grids of DAV star models are evolved by \texttt{WDEC}, taking the element diffusion effect into account. The grid parameters are hydrogen mass log(), helium mass log($…
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…
Asteroseismology of the DBV star CBS 114
Yanhui Chen
Asteroseismology is an unique and powerful tool to detect the internal structure of stars. CBS 114 is the sixth known pulsating DBV star. It was observed by Handler, Metcalfe, \& W…
The dispersion of period spacing for DAV stars
Yanhui Chen
Three groups of DAV star models are evolved with time-dependent element diffusion by \texttt{WDEC}. The core compositions of these models are directly from white dwarf models evolv…
The Comparison of Stellar Atomspheric Parameters between LAMOST and APOGEE databases
Y. Q. Chen, G. Zhao, C. Liu +8
We have compared the stellar parameters, temperature, gravity and metallicity, between the LAMOST-DR2 and SDSS-DR12/APOGEE database for stars in common. It is found that the LAMOST…
Asteroseismology of DAV star HS0507+0434B, including the core composition profiles
YanHui Chen, Yan Li
The DAV star, HS0507+0434B, was observed by Fu et al. (2013) in 2007 and from 2009 December to 2010 January. There were a total of six triplets with nearly equal split, which were…
Asteroseismology of DAV white dwarf stars and G29-38
Yan-Hui Chen, Yan Li
Asteroseismology is a powerful tool to detect the inner structure of stars. It is also widely used to study white dwarfs. In this paper, we discuss the asteroseismology work of DAV…
