Gravitoviscous Protoplanetary Discs with a Dust Component. IV. Disc Outer Edges, Spectral Indices, and Opacity Gaps

Vitaly Akimkin, Eduard Vorobyov, Yaroslav Pavlyuchenkov +1

The crucial initial step in planet formation is the agglomeration of micron-sized dust into macroscopic aggregates. This phase is likely to happen very early during the protostella…

ALMA and VLA Observations of EX Lupi in its Quiescent State

Jacob Aaron White, Á. Kóspál, A. G. Hughes +15

Extreme outbursts in young stars may be a common stage of pre-main-sequence stellar evolution. These outbursts, caused by enhanced accretion and accompanied by increased luminosity…

Gravitoviscous protoplanetary disks with a dust component. III. Evolution of gas, dust, and pebbles

Vardan G. Elbakyan, Anders Johansen, Michiel Lambrechts +2

We study the dynamics and growth of dust particles in circumstellar disks of different masses that are prone to gravitational instability during the critical first Myr of their evo…

The origin of tail-like structures around protoplanetary disks

E. I. Vorobyov, A. M. Skliarevskii, V. G. Elbakyan +4

We study the origin of tail-like structures recently detected around the disk of SU Aurigae and several FU~Orionis-type stars. Dynamic protostellar disks featuring ejections of gas…

Chemical modelling of FU Ori protoplanetary disks

Tamara Molyarova, Vitaly Akimkin, Dmitry Semenov +5

Luminosity outbursts of the FUOri type stars, which have a magnitude of and last for decades, may affect chemical composition of the surrounding protoplanetary…
