We present a spectral study of the single magnetically active K giant OP And in the period 1979 -- 2018, monitoring the variability of the activity indicator line H${\alpha}$. Original data obtained in the period 2015 -- 2018 with the echelle spectro

In this paper we describe the echelle spectrograph of the 2 meter telescope of the Rozhen National Astronomical Observatory. The spectrograph is a cross-dispersed, bench-mounted, fiber-fed instrument giving a resolution from $\sim$30000 to $\sim$4500

The interest in polarimetric and spectropolarimetric observations increased in the last few years. In this poster, we report polarimetric and spectropolarimetric observations of standard stars with a low and high degree of linear polarisation obtaine

In three selected M giants, EK Boo, RZ Ari and β Peg, we investigate the long-term behavior and the possible mechanims for magnetic field generation in the context of stellar evolution.

Beta Ceti is a slowly rotating (v sin i = 3.5 kms−1) single giant. In our previous study (Tsvetkova et al. (2013)) we showed that it is in the core He-burning phase and we reconstructed two Zeeman Doppler imaging (ZDI) maps (using data from 2010 an
