Hydrodynamics modeling of the water snow line in young protoplanetary disks with dust-size-dependent opacities
Eduard I. Vorobyov, Anastasiia Topchieva, Aleksandr Skliarevskii +2
Aims. We investigated the properties of the water snow line during the early stages of disk evolution, paying particular attention to the effects of gravitational instability and d…
Mapping Interstellar Ice Inventory toward Class 0 Protostars in Star-forming Region Orion A with JWST Data
Igor Petrashkevich, Yaroslav Pavlyuchenkov, Anna Punanova +7
We present a detailed study of the spatial distribution and chemical composition of interstellar ices toward six Class 0 protostars (HOPS-56, HOPS-60, HOPS-73, HOPS-91, HOPS-96, an…
Single-dish observations and non-LTE analysis of CH3OH, HCN, and CO line emission in the Oort cloud comet C/2017 K2 (PANSTARRS)
M. S. Kirsanova, Ya. N. Pavlyuchenkov, A. O. H. Olofsson +1
We present pre-perihelion observations of methanol, carbon monoxide, and hydrogen cyanide in the Oort cloud comet C/2017 K2 (PANSTARRS), performed with the APEX 12-m and Onsala 20-…
Tracking the dynamical, chemical and spectral evolution of molecular cores with PrestaLine: Gorynych
Olga Kochina, Dmitri Wiebe, Yaroslav Pavlyuchenkov +1
We present PrestaLine: Gorynych, a comprehensive numerical tool designed to model the dynamical, chemical, and spectral evolution of collapsing molecular cores from the prestellar…
Time-dependent response of protoplanetary disk temperature to an FU Ori-type luminosity outburst
S. I. Laznevoi, V. V. Akimkin, Ya. N. Pavlyuchenkov +3
Context. The most prominent cases of young star variability are accretion outbursts in FU Ori-type systems. The high power of such outbursts causes dramatic changes in the physical…
Modeling the Thermal Structure of a Protoplanetary Disk Using Multiband Flux-Limited Diffusion Approximation
Ya. N. Pavlyuchenkov, V. V. Akimkin
This work continues the analysis of the model for calculating the thermal structure of an axisymmetric protoplanetary disk, initiated in the paper by Pavlyuchenkov (2024). The mode…
