Distribution of the magnetic field relative to the plane of the Galaxy in the region of the Sagittarius spiral arm
R. R. Andreasyan, H. R. Andreasyan, A. M. Mickaelian +2
Faraday rotation data for 492 pulsars and more than 2,700 extragalactic radio sources were used to study the magnetic field, in detail, in the direction of Galactic longitude $33^o…
New Herbig-Haro Objects associated with Embedded Sources
T. A. Movsessian, T. Yu. Magakian, B. Reipurth +1
We continue to present the results of the Byurakan Narrow Band Imaging Survey (BNBIS). The main goal of this survey is to search for Herbig-Haro (HH) objects and jets in Galactic d…
The star in RNO 54 -- a post-FUor with short faint jet?
T. Yu. Magakian, T. A. Movsessian, H. R. Andreasyan +2
The aim of the present study was the spectral analysis of an unusual pre-main-sequence star in the cometary nebula RNO 54, which was suspected by several researchers as a FUori-lik…
Herbig-Haro Flows and Young Stars in the Dobashi 5006 Dark Cloud
T. A. Movsessian, T. Yu. Magakian, A. S. Rastorguev +1
Two new Herbig-Haro flows were found in a study of the isolated Dobashi 5006 dark cloud (l, b= 13): one certain (HH 1179) and one presumable, associated…
FUors, EXors and the role of intermediate objects
T. Yu. Magakian, T. A. Movsessian, H. R. Andreasyan
The studies of FUors, EXors and other young eruptive stars are very important for the understanding of the earliest stages of pre-main-sequence evolution. We describe the current s…
PV Cep and V350 Cep: stars on the way between FUors AND EXors
H. R. Andreasyan, T. Yu. Magakian, T. A. Movsessian +1
Based on new observations during 2015-2020 and published data, the unusual eruptive variables PV Cep and V350 Cep are examined. It is shown that PV Cep underwent a regular outburst…
Spectral study of V565 Mon: Probable FU Ori-like or chemically peculiar star
Hasmik Andreasyan
We present the detailed spectroscopic study of V565 Mon pre-main-sequence star, which is the illuminating star of Parsamian 17 cometary nebula. Observations were performed with 2.6…
Herbig-Haro flows around BBWo 192E (GM 1-23) nebula
T. Yu. Magakian, T. A. Movsessian, H. R. Andreasyan +2
We studied a small comet-shape reflection nebula, located in the dark cloud SL 4 in the Vela Molecular Ridge cloud C, known as BBWo 192E (GM 1-23), and a young infrared cluster emb…
New powerful outburst of the unusual young star V1318 Cyg S (LkHα 225)
T. Yu. Magakian, T. A. Movsessian, H. R. Andreasyan +1
Young double star V1318 Cyg, which is associated with a small isolated star-forming region around HAeBe star BD+40o4124, has very unusual photometric and spectral behavior. We pres…
On the magnetic field inside the solar circle of the Galaxy: On the possibility of investigation some of characteristics of the interstellar medium with using of pulsars with large Faraday rotation values
R. R. Andreasyan, H. R. Andreasyan, G. M. Paronyan
To study some characteristics of the interstellar medium, observational data of pulsars with large Faraday rotation values (|RM|> 300 rad / m2) were used. It was suggested and just…
