The beta Pictoris association: Catalog of photometric rotational periods of low-mass members and candidate members
S. Messina, M. Millward, A. Buccino +19
We intended to compile the most complete catalog of bona fide members and candidate members of the beta Pictoris association, and to measure their rotation periods and basic proper…
Chromospheric activity on the late-type star V1355 Ori using Lijiang 1.8-m and 2.4-m telescopes
Qing-Feng Pi, Li-Yun Zhang, Liang Chang +4
We obtained new high-resolution spectra using the Lijiang 1.8-m and 2.4-m telescopes to investigate the chromospheric activities of V1355 Ori as indicated in the behaviors of Ca ii…
Chromospheric activity on late-type star DM UMa using high-resolution spectroscopic observations
LiYun Zhang, QingFeng Pi, Xianming L. Han +2
We present new 14 high-resolution echelle spectra to discuss the level of chromospheric activity of DM UMa in {He I} D3, {Na I} D1, D2, Halpha, and {Ca II} infrared triplet lines (…
Two Dimensional Classification of the Swift/BAT GRBs
E. B. Yang, Z. B. Zhang, X. X. Jiang
Using Gaussian Mixture Model and Expectation Maximization algorithm, we have performed a density estimation in the framework of versus hardness ratio for 296 Swift/BAT GRB…
