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…

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…

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…
