The most evolved sources in the Hi-GAL survey
Elia, D.
Far-infrared and submillimetre surveys as the Herschel Galactic Plane Infrared Survey (Hi-GAL) represent an irreplaceable knowledge base about early phases of star formation, permitting statistical analysis based on thousands of Galaxy-wide distributed sources. Those with a regular spectral energy distribution in the Herschel wavelength range 70-5…
M Giants found in the First Byurakan Spectral Sky Survey data base. V. GAIA DR2 data
Gigoyan, K.
In this paper we study bright M {type giants found in the First Byurakan Survey (FBS) low-resolution (lr) spectroscopic data base. Phase dependence light-curves from large sky area variability data bases such as Catalina Sky Survey (CSS) and All-Sky Automated Survey for Supernovae (ASAS-SN), and the second Gaia data release data (Gaia DR2) high-qu…
FSR19 and FSR25 confirmed as two new faint and metal-rich globular clusters in the galactic bulge
Minniti, D.; Alonso-García, J.; Gómez, M. +1 more
We combined the near-IR photometry from the VISTA Variables in the Vía Láctea extended Survey (VVVX) with Gaia EDR3 catalog to study some properties of FSR19 and FSR25. These are confirmed to be low luminosity metal-rich bulge globular clusters (Obasi et al. 2020). The proper motions (PM) remain unchanged and the Color magnitude diagrams (CMD) are…
Investigation of faint galactic carbon stars from the First Byurakan Spectral Sky Survey. IV. GAIA DR2 data
Kostandyan, G. R.
The second Gaia data release (Gaia DR2) data are used to analyze and estimate some important parameters for 127 carbon (C) type stars (56 are late N - type Asymptotic Giant Branch (AGB) C stars, 71 are early type CH giants) detected on the First Byurakan Spectral Sky Survey (FBS) low-resolution (lr) spectral plates. Gaia DR2 G broad band magnitude…
Kinematic and dynamic properties of young stellar cluster IC 348
Nikoghosyan, E. H.; Azatyan, N. M.; Harutyunian, H. A. +1 more
In 30 - 40s of the last century Viktor Ambartsumian has published several studies on the kinematics and dynamics of stellar systems. The scientific issues of these papers not only remain relevant up to nowadays, but also are of key importance for the construction of the generalized theory of star formation. The launch of the Gaia spacecraft on Dec…
Identifying birth places of high-velocity stars
Hambaryan, V.
We searched for the high-velocity and isolated neutron stars that encountered in the past with a stellar cluster/association closer than 20 pc. We took about 830000 stars with the high-quality astrometry and radial velocities from the Gaia DR2 catalogue and empirically selected about 560 high-velocity stars. We used a full gravitational potential …
Revised and updated catalogue of the First Byurakan Survey of late-type stars: 2nd edition
Gigoyan, K. S.; Kostandyan, G. R.; Mickaelian, A. M.
Eighteen lists of late-type stars (LTSs) have been published between 1990 and 2016. These LTSs have been found in the low-dispersion spectroscopic plates of the First Byurakan Survey (FBS). The systematic search and selection was carried out on a surface _16000 deg2 on almost the whole area of the FBS. As a result, “Revised and Updated Catalogue o…
