K2 photometry is suitable for the exploitation of mode variability on short timescales in hot B subdwarf stars, which is important to constrain nonlinear quantities addressed by th…
A Study of Pulsation properties of 57 Non-Blazhko effect ab-type RR Lyrae stars with homogeneous metallicities from the LAMOST-Kepler/K2 survey
Peng Zong, Jian-Ning Fu, Jiaxin Wang +4
Homogeneous metallicities and continuous high-precision light curves play key roles in studying the pulsation properties of RR Lyrae stars. By cross-matching with LAMOST DR6, we ha…
K2 photometry on oscillation mode variability: the new pulsating hot B subdwarf star EPIC 220422705
Xiao-Yu Ma, Weikai Zong, Jian-Ning Fu +4
We present an analysis of oscillation mode variability in the hot B subdwarf star EPIC~220422705, a new pulsator discovered from ~days of {\em K}2 photometry. The high-qual…
Searching Extra-tidal Features around the Globular Cluster Whiting 1
Jundan Nie, Hao Tian, Jing Li +14
Whiting 1 is a faint and young globular cluster in the halo of the Milky Way, and was suggested to have originated in the Sagittarius spherical dwarf galaxy (Sgr dSph). In this pap…
The Properties and Evolutions of Starspots on Three Detached Eclipsing Binaries in the LAMOST-Kepler survey
