Prominence activation, optical flare, and post-flare loops on the RS Canum Venaticorum star SZ Piscium
Dongtao Cao, Shenghong Gu, Jian Ge +7
We present the results of time-resolved high-resolution spectroscopic observations of the very active RS Canum Venaticorum (RS CVn) star SZ Piscium (SZ Psc), obtained during two co…
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 (…
UV-Optical Observation of Type Ia Supernova SN 2013dy in NGC 7250
Qian Zhai, JuJia Zhang, XiaoFeng Wang +15
Extensive and independent observations of Type Ia supernova (SN Ia) SN 2013dy are presented, including a larger set of photometry and optical spectra from a few days before…
Optical observations of a SN 2002cx-like peculiar supernova SN 2013en in UGC 11369
Zheng-Wei Liu, Jujia Zhang, Fabrizio Ciabattari +7
We present optical observations of a SN 2002cx-like supernova SN 2013en in UGC 11369, spanning from a phase near maximum light (t= +1 d) to t= +60 d with respect to the R-band maxi…
