The formation of blue large-amplitude pulsators from white-dwarf main-sequence star mergers
Xianfei Zhang, C. Simon Jeffery, Jie Su +1
Blue large-amplitude pulsators (BLAPs) are hot low-mass stars which show large-amplitude light variations likely due to radial oscillations driven by iron-group opacities. Period c…
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…
A fast point-pattern matching algorithm based on statistical method
Zhen-Jun Zhang, Yi-Gong Zhang, Xiang-Ming Cheng +2
We propose a new pattern-matching algorithm for matching CCD images to a stellar catalogue based statistical method in this paper. The method of constructing star pairs can greatly…
CCD astrometric observations of 2017 VR12,Camillo and Midas
Zhenjun Zhang, Yigong Zhang, Xiangming Cheng +2
We have observed three near-Earth objects(NEOs), 2017VR12, Camillo, and Midas during the year 2018. The observations were made by the 1-m telescope of Yunnan Observatory over 2 nig…
Asteroseismology of the ZZ Ceti star KUV 11370+4222
J. Su, Y. Li, J. -N. Fu +1
KUV 11370+4222 is a ZZ Ceti star discovered in 1996, which has not been observed since then. We performed observations for KUV 11370+4222 in 2010 January. From the Fourier transfor…
On the DB gap of white dwarf evolution: effects of hydrogen mass fraction and convective overshooting
Jie Su, Yan Li
We investigate the spectral evolution of white dwarfs by considering the effects of hydrogen mass in the atmosphere and convective overshooting above the convection zone. We notice…
