Yet another star in the Albireo system -- The discovery of Albireo Ad
D. Jack, K. -P. Schröder, M. Mittag +1
Context. Albireo is a well-known bright visual double star. It is still unclear if the components A and B form a gravitationally bound system. The component Albireo A is itself a b…
CARMENES input catalog of M dwarfs VI. A time-resolved Ca II H&K catalog from archival data
V. Perdelwitz, M. Mittag, L. Tal-Or +15
Radial-velocity (RV) jitter caused by stellar magnetic activity is an important factor in state-of-the-art exoplanet discovery surveys such as CARMENES. Stellar rotation, along wit…
Magnetic field and chromospheric activity evolution of HD75332: a rapid magnetic cycle in an F star without a hot Jupiter
E. L. Brown, S. C. Marsden, M. W. Mengel +10
Studying cool star magnetic activity gives an important insight into the stellar dynamo and its relationship with stellar properties, as well as allowing us to place the Sun's magn…
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…
Magnetic activity and evolution of the four Hyades K giants
Klaus-Peter Schröder, Marco Mittag, Dennis Jack +2
We determine the exact physical parameters of the four Hyades cluster K giants, using their parallaxes and atmospheric modeling of our red-channel TIGRE high-resolution spectra. Pe…
