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…

Deuteration of water in protoplanetary discs during luminosity outbursts: model predictions for FU Ori discs
Anastasiia Topchieva, Tamara Molyarova, Anton Vasyunin
Luminosity outbursts of FU Ori-type objects (FUors) allow us to observe in the gas the molecules that are typically present in the ice in protoplanetary discs. In particular, the f…

The Effect of Luminosity Outbursts on the Abundance of Pebbles and Their Ice Mantles in Protoplanetary Disks
Anastasiia Topchieva, Tamara Molyarova, Eduard Vorobyov
Centimeter-sized dust grains-pebbles-are necessary for planetesimal formation via the streaming instability, they play an important role in forming protoplanetary cores and giant p…
