Study of the physical and chemical properties of dense clumps at different evolutionary stages in several regions of massive star and stellar cluster formation

A. G. Pazukhin, I. I. Zinchenko, E. A. Trofimova

Massive stars play an important role in the Universe. Unlike low-mass stars, the formation of these objects located at great distances is still unclear. It is expected to be govern…

Variations of the HCO $^{+}$ , HCN, HNC, N $_{2}$ H $^{+}$ and NH $_{3}$ deuterium fractionation in high-mass star-forming regions

A. G. Pazukhin, I. I. Zinchenko, E. A. Trofimova +2

We use spectra and maps of the $J = 1 - 0$ and $J = 2 - 1$ DCO $^{+}$ , DCN, DNC, $N_{2} D^{+}$ lines and $1_{11} - 1_{01}$ ortho- and para-NH $_{2}$ D lines, obtained with the IRAM-30m telescope…

Fragmentation and dynamics of dense gas structures in the proximity of massive young stellar object W42-MME

N. K. Bhadari, L. K. Dewangan, L. E. Pirogov +4

We present an analysis of the dense gas structures in the immediate surroundings of the massive young stellar object (MYSO) W42-MME, using the high-resolution (0 $^{''}$ .31 $\times$ 0$''…

H $^{13}$ CN-HN $^{13}$ C intensity ratio as a temperature indicator of interstellar clouds

A. G. Pazukhin, I. I. Zinchenko, E. A. Trofimova +1

With the 30-m IRAM radio telescope, we observed several massive star forming regions at wavelengths of 3-4 and 2 mm. The temperature of the gas in the sources was estimated from th…

Deuterated molecules in regions of high-mass star formation

Igor I. Zinchenko, Andrey G. Pazukhin, Elena A. Trofimova +3

We present the results of our studies of deuterated molecules (DCN, DNC, DCO $^{+}$ , N $_{2}$ D $^{+}$ and NH $_{2}$ D) in regions of high-mass star formation, which include a survey of such reg…

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…
