Optical Spectroscopy of the IR Source CPM 19 and Surrounding Objects
T. Yu. Magakian, T. A. Movsessian, A. V. Moiseev +2
Optical spectra of the well-known infrared source CPM~19, which exhibited a strong decline in brightness during the period from 1984--1987 to 2000--2005, have been obtained for the…

Dancing on the Grain: Variety of CO and its isotopologue fluxes as a result of surface chemistry and T Tauri disk properties
L. Zwicky, T. Molyarova, Ã. Kóspál +1
At the moment, one of the main ways to infer the disk mass is to use a combination of CO isotopologue line observations. A number of theoretical studies have concluded that CO must…

The impact of rates of reactions with cosmic ray induced photons on chemical composition of protoplanetary discs
L. N. Zwicky, T. S. Molyarova
Cosmic rays and cosmic ray induced photons are vital components of chemical evolution in areas of interstellar medium that are impenetrable by external ultraviolet radiation. Howev…
