The role of detailed gas and dust opacities in shaping the evolution of the inner disc edge subject to episodic accretion
Michael Cecil, Mario Flock, Mykola G. Malygin +4
We investigate the effects of different dust and gas opacity descriptions on the structure and evolution of the inner regions of protoplanetary discs. The influence on the episodic…
Observational Signatures of Planetary Tidal Disruption Events Around Solar-Mass Stars
Matías Montesinos, Sergei Nayakshin, Vardan Elbakyan +4
The tidal disruption of planets by their host stars represents a growing area of interest in transient astronomy, offering insights into the final stages of planetary system evolut…
On the accuracy of mass and size measurements of young protoplanetary disks
Eduard I. Vorobyov, Aleksandr Skliarevskii, Vardan Elbakyan +2
Knowing the masses and sizes of protoplanetary disks is of fundamental importance for the contemporary theories of planet formation. However, their measurements are associated with…
Dust enrichment and growth in the earliest stages of protoplanetary disk formation
E. I. Vorobyov, V. G. Elbakyan, A. Skliarevskii +2
Aims. We numerically investigated dust enrichment and growth during the initial stages of protoplanetary disk formation. A particular objective was to determine the effects of vari…
Dust growth and pebble formation in the initial stages of protoplanetary disk evolution
Eduard Vorobyov, Igor Kulikov, Vardan Elbakyan +2
Aims. The initial stages of planet formation may start concurrently with the formation of a gas-dust protoplanetary disk. This makes the study of the earliest stages of protoplanet…
On the origin of accretion bursts in FUORs
Sergei Nayakshin, Vardan Elbakyan
Accretion luminosity of young star FU Ori increased from undetectable levels to hundreds of Solar luminosities in 1937 and remains nearly as high at the present time. In a recent p…
Distinguishing Magnetized Disc Winds from Turbulent Viscosity through Substructure Morphology in Planet-forming Discs
Yinhao Wu, Yi-Xian Chen, Haochang Jiang +5
The traditional paradigm of viscosity-dominated evolution of protoplanetary discs has been recently challenged by magnetized disc winds. However, distinguishing wind-driven and tur…
Extreme evaporation of planets in hot thermally unstable protoplanetary discs: the case of FU Ori
Sergei Nayakshin, James E. Owen, Vardan Elbakyan
Disc accretion rate onto low mass protostar FU Ori suddenly increased hundreds of times 85 years ago and remains elevated to this day. We show that the sum of historic and recent o…
Formation of pebbles in (gravito-)viscous protoplanetary disks with various turbulent strengths
Eduard I. Vorobyov, Vardan G. Elbakyan, Anders Johansen +3
Aims. Dust plays a crucial role in the evolution of protoplanetary disks. We study the dynamics and growth of initially sub- dust particles in self-gravitating young protoplane…
Gap opening by planets in discs with magnetised winds
Vardan Elbakyan, Yinhao Wu, Sergei Nayakshin +1
Planets open deep gaps in protoplanetary discs when their mass exceeds a gap opening mass, . We use one- and two-dimensional simulations to study planet gap opening in…
ALMA constraints on assembly of Core Accretion planets
Sergei Nayakshin, Vardan Elbakyan, Giovanni Rosotti
Resolved dust continuum and CO line ALMA imaging, and in some cases detection of H emission, hint that young massive planets are abundant at wide separations in protoplanetary d…
Millimeter-sized Dust Grains Appear Surviving the Water-sublimating Temperature in the Inner 10 au of the FU Ori Disk
Hauyu Baobab Liu, An-Li Tsai, Wen Ping Chen +10
Previous observations have shown that the 10 au, 400 K hot inner disk of the archetypal accretion outburst young stellar object, FU Ori, is dominated by viscous…
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…
Gravitoviscous protoplanetary disks with a dust component. I. The importance of the inner sub-au region
Eduard I. Vorobyov, Aleksandr M. Skliarevskii, Vardan G. Elbakyan +3
The central region of a circumstellar disk is difficult to resolve in global numerical simulations of collapsing cloud cores, but its effect on the evolution of the entire disk can…
