A long-term study of the magnetic field and activity in the M giant RZ Ari
R. Konstantinova-Antova, S. Georgiev, A. Lèbre +12
We present a detailed long-term study of the single M6 III giant RZ~Ari to obtain direct and simultaneous measurements of the magnetic field, activity indicators, and radial veloci…
A Long-Term Spectral Study of the Single Active Giant OP Andromedae
Stefan Georgiev, Renada Konstantinova-Antova, Ana Borisova +10
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. Original da…
ESpeRo: Echelle Spectrograph Rozhen
Tanyu Bonev, Haralambi Markov, Toma Tomov +11
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, f…
Magnetic field structure in single late-type giants: Beta Ceti in 2010 - 2012
S. Tsvetkova, P. Petit, M. Auriere +5
The data were obtained using two spectropolarimeters - Narval at the Bernard Lyot Telescope, Pic du Midi, France, and ESPaDOnS at CFHT, Hawaii. Thirty-eight circularly-polarized sp…
Magnetic Field and Activity of the Single Late-type Giant Beta Ceti
S. Tsvetkova, M. Auriere, R. Konstantinova-Antova +3
We present the behavior of the magnetic field and activity indicators of the single late-type giant Beta Ceti in the period June 19, 2010 - December 14, 2010. We used spectropolari…
Magnetic field structure in single late-type giants: The effectively single giant V390 Aur
R. Konstantinova-Antova, M. Auriere, P. Petit +4
We have studied the active giant V390 Aur using spectropolarimetry to obtain direct and simultaneous measurements of the magnetic field and the activity indicators in order to get…
The Synchronous Network of distant Telescopes
B. Zhilyaev, O. Svyatogorov, I. Verlyuk +9
The Synchronous Network of distant Telescopes (SNT) represents an innovative approach in observational astrophysics. Authors present the unique existing realization of the SNT-conc…
