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…
Prominence detection and chromosphere feature on the prototype RS CVn of active binary systems
Dongtao Cao, Shenghong Gu, U. Wolter +4
We present a study of high-resolution spectra of RS Canum Venaticorum (RS CVn), a prototype of active binary systems. Our data were obtained from 1998 to 2017 using different teles…
Time series of optical spectra of Nova V659 Sct
Dennis Jack, Klaus-Peter Schröder, Philippe Eenens +4
With our robotic 1.2 m TIGRE telescope, we were able to obtain eight optical spectra with intermediate resolution (R = 20,000) of the Nova V659 Sct during different phases of its o…
An X-ray activity cycle on the young solar-like star
M. Coffaro, B. Stelzer, S. Orlando +7
In 2015 we started the XMM-Newton monitoring of the young solar-like star Epsilon Eridani (440 Myr), one of the youngest solar-like stars with a known chromospheric CaII cycle. By…
The first Doppler imaging of the active binary prototype RS Canum Venaticorum
Yue Xiang, Shenghong Gu, U. Wolter +6
We present the first Doppler images of the prototypical active binary star RS CVn, derived from high-resolution spectra observed in 2004, 2016 and 2017, using three different teles…
An eccentric wave in the circumstellar disc of the Be/X-ray binary X Persei
R. K. Zamanov, K. A. Stoyanov, U. Wolter +7
We present spectroscopic observations of the Be/X-ray binary X Per obtained during the period December 2017 - January 2020 (MJD~58095 - MJD~58865). In December 2017 the , ,…
