Identifying Evolutionary Stages of Molecular Clumps through Unsupervised and Supervised Machine Learning
K. V. Plakitina, M. S. Kirsanova, A. B. Ostrovskii +3
The evolutionary classification of molecular clumps, crucial for understanding star formation, is commonly based on human-assigned categories derived from infrared (IR) emission an…
Off-lattice Microscopic Monte Carlo Modeling of Molecular Hydrogen Formation on Carbonaceous Dust Grains
N. A. Satonkin, A. B. Ostrovskii, A. A. Mozhegorov +2
In this work, we present an off-lattice Monte Carlo model of accretion and migration of hydrogen atoms on a rough surface of carbon dust grain. The migration of physisorbed atoms b…
Electronic structure of the CuO monolayer in the paramagnetic phase considering the Coulomb interactions
I. A. Makarov, A. A. Slobodchikov, I. A. Nekrasov +4
The electronic structure of the CuO monolayer is investigated taking into account the intra- and interatomic Coulomb interactions on copper and oxygen atoms. Local Coulomb interact…
Chemical differentiation and gas kinematics around massive young stellar objects in RCW 120
K. V. Plakitina, M. S. Kirsanova, S. V. Kalenskii +2
We present results of a spectral survey towards a dense molecular condensation and young stellar objects (YSOs) projected on the border of the HII region RCW 120 and discuss emissi…
Luminosity Outbursts in Interacting Protoplanetary Systems
Aleksandr M. Skliarevskii, Eduard I. Vorobyov
FU Orionis type objects (fuors) are characterized by rapid (tens to hundreds years) episodic outbursts, during which the luminosity increases by orders of magnitude. One of the pos…
