The FeII Optical Emission in AGN
C. Bongardo, R. Zamanov, P. Marziani +2
We investigated the optical FeII emission in a sample of about 215 low-redshift AGN (quasars and luminous Seyfert 1 galaxies). We find that a scaled and broadened FeII template bas…
The Be/X-ray Binary LSI+61303 in terms of Ejector-Propeller Model
R. Zamanov, J. Marti, P. Marziani
We tested the ejector-propeller model of the Be/X-ray binary LSI+61303 (V 615 Cas, GT 0236+620) by using the parameters predicted by the model in the calculations of the X-ray and…
Confirmation of a moving component in the H-alpha emission line of LSI+61303
R. Zamanov, J. Marti
We report our attempts to detect and confirm a narrow moving component in the H-alpha emission line of the radio emitting Be/X-ray binary LSI+61 303 (V615 Cas, GT0236+610). The exi…
First correlation between compact object and circumstellar disk in the Be/X-ray binaries
R. Zamanov, J. Marti
A remarkable correlation between the H-alpha emission line and the radio behaviour of LSI+61 303 (V615 Cas, GT 0236+610) over its 4 yr modulation is discovered. The radio outburst…
Evidence of H alpha periodicities in LS I+61303
R. K. Zamanov, J. Marti, J. M. Paredes +3
We present the results of analyzing H spectra of the radio emitting X-ray binary LS I+61303. For the first time, the same 26.5 d radio period is clearly detected in the H emi…
Photometric and H observations of LSI+61303: detection of a 26 day V and JHK band modulation
J. M. Paredes, P. Marziani, J. Marti +12
We present new optical and infrared photometric observations and high resolution H spectra of the periodic radio star \lsi. The optical photometric data set covers the time inte…
