Correlation between formaldehyde and methanol in prestellar cores

A. F. Punanova, K. Borshcheva, G. S. Fedoseev +3

Formaldehyde is a key precursor in the formation routes of many complex organic molecules (COMs) in space. It is also an intermediate step in CO hydrogenation sequence that leads t…

Impact of HAC evolution on the formation of small hydrocarbons in the Orion Bar and the Horsehead PDRs

M. S. Murga, A. I. Vasyunin, M. S. Kirsanova

We study evolution of hydrogenated amorphous carbon (HAC) grains under harsh UV radiation in photo-dissociation regions (PDRs) near young massive stars. Our aim is to evaluate the…

Dark cloud-type chemistry in PDRs with moderate UV field

Maria S. Kirsanova, Anna F. Punanova, Dmitry A. Semenov +1

We present a study of emission lines of small hydrocarbons CH and -CH, and COMs precursors HCO and CHOH in order to better understand the possible chemical l…

Detection of Complex Organic Molecules in Young Starless Core L1521E

Samantha Scibelli, Yancy Shirley, Anton Vasyunin +1

Determining the level of chemical complexity within dense starless and gravitationally bound prestellar cores is crucial for constructing chemical models, which subsequently constr…

Impact of PAH photodissociation on the formation of small hydrocarbons in the Orion Bar and the Horsehead PDRs

M. S. Murga, M. S. Kirsanova, A. I. Vasyunin +1

We study whether polycyclic aromatic hydrocarbons (PAHs) can be a weighty source of small hydrocarbons in photo-dissociation regions (PDRs). We modeled the evolution of 20 specific…

Optical properties and dust temperatures in clumpy diffuse medium

Andrei B. Ostrovskii, S. Yu. Parfenov, A. I. Vasyunin +2

In this study, we explore the impact of inhomogeneities in the spatial distribution of interstellar dust on spatial scales of au caused by ion shadowing forces on the optica…
