Properties of Contracting Massive Protostellar Cores
L. E. Pirogov, P. M. Zemlyanukha, E. M. Dombek
Studies of the structure and kinematics of cores associated with the regions of massive star and star cluster formation are necessary for constructing scenario for the evolution of…
Physical Properties and Kinematics of Dense Cores Associated with Regions of Massive Star Formation from the Southern Sky
L. E. Pirogov, P. M. Zemlyanukha, E. M. Dombek +1
The results of spectral observations in the GHz frequency range of six objects in the southern sky containing dense cores and associated with regions of massive stars…
Fragmented atomic shell around S187 HII region and its interaction with molecular and ionized gas
Petr Zemlyanukha, Igor I. Zinchenko, Evgeny Dombek +6
The environment of S187, a nearby H II region (1.40.3 kpc), is analyzed. A surrounding shell has been studied in the H I line, molecular lines, and also in infrared and radio…
The disk-outflow system around the rare young O-type protostar W42-MME
L. K. Dewangan, I. I. Zinchenko, P. M. Zemlyanukha +6
We present line and continuum observations (resolution ~0.3"-3.5") made with the Atacama Large Millimeter/submillimeter Array (ALMA), Submillimeter Array, and Very Large Array of a…
Probing gas kinematics and PDR structure around O-type stars in Sh 2-305 HII region
N. K. Bhadari, L. K. Dewangan, P. M. Zemlyanukha +3
We report an observational study of the Galactic HII region Sh 2-305/S305 using the [CII] 158 m line data, which are used to examine the gas dynamics and structure of photodisso…
Principal component analysis for estimating parameters of the L1287 dense core by fitting model spectral maps into observed ones
L. E. Pirogov, P. M. Zemlyanukha
An algorithm has been developed for finding the global minimum of a multidimensional error function by fitting model spectral maps into observed ones. Principal component analysis…
The Spatial-Kinematic Structure of the Region of Massive Star Formation S255N on Various Scales
P. M. Zemlyanukha, I. I. Zinchenko, S. V. Salii +2
The results of a detailed analysis of SMA, VLA, and IRAM observations of the region of massive star formation S255N in CO(2---1), \nh, \nhh, \co and some other lines is presented.…
Multi-frequency Studies of Massive Cores with Complex Spatial and Kinematic Structures
L. E. Pirogov, V. M. Shul'ga, I. I. Zinchenko +3
Five regions of massive star formation have been observed in various molecular lines in the frequency range GHz. The studied regions possess dense cores, which host yo…
The disk-outflow system in the S255IR area of high mass star formation
I. Zinchenko, S. -Y. Liu, Y. -N. Su +7
We report the results of our observations of the S255IR area with the SMA at 1.3 mm in the very extended configuration and at 0.8 mm in the compact configuration as well as with th…
