Connection between orbital modulation of H-alpha and gamma-rays in the Be/X-ray binary LSI+61303
R. Zamanov, J. Martí, K. Stoyanov +2
We studied the average orbital modulation of various parameters (gamma-ray flux, H-alpha emission line, optical V band brightness) of the radio- and gamma-ray emitting Be/X-ray bin…
H-alpha observations of the gamma-ray-emitting Be/X-ray binary LSI+61303: orbital modulation, disk truncation, and long-term variability
R. Zamanov, K. Stoyanov, J. Marti +4
We report 138 spectral observations of the H-alpha emission line of the radio- and gamma-ray-emitting Be/X-ray binary LSI+61303 obtained during the period of September 1998 -- Janu…
The awakening of BL Lacertae: observations by Fermi, Swift, and the GASP-WEBT
C. M. Raiteri, M. Villata, F. D'Ammando +4
Since the launch of the Fermi satellite, BL Lacertae has been moderately active at gamma-rays and optical frequencies until May 2011, when the source started a series of strong fla…
Photometric and spectroscopic variability of the FUor star V582 Aurigae
E. H. Semkov, S. P. Peneva, U. Munari +5
We carried out BVRI CCD photometric observations in the field of V582 Aur from 2009 August to 2013 February. We acquired high-, medium-, and low-resolution spectroscopy of V582 Aur…
