Fabry-perot Hα-interferometric observations of some HII regions. I. SH2-152 and SH2-153

H -interferometric observations of the HII-regions Sh2-152 and Sh2-153 are carried out with a high resolution (1 pixel=2.13×2.13 arcsec). They confirm the results on the structure of those formations obtained earlier. Individual radial velocities determined in different points for each of these HII-regions show that the inner motions of ionized matter relative to the exciting stars are, in general, of expanding character. It gives ground to assume that in both these star forming regions the dissipation of matter takes place.Published in Astrofizika, Vol. 37, No. 2, pp. 175–186, April–June, 1994.     

At the 2.6 m telescope of Byurakan Perot-Fabry observations of gas emission in nebulae with cigale

During the summer of 1985, the CIGALE Perot-Fabry scanning interferometer of Marseilles Observatory was installed at the prime focus of the 2.6 m telescope of Byurakan Observatory. The long run (two new moons) was successful and gave matereial for numerous publications.Published in Astrofizika, Vol. 38, No. 4, pp. 619–624, October–December, 1995.
