Magnetohydrodynamical opening of dust traps in protoplanetary disks
Sergey Khaibrakhmanov, Vitaly Akimkin
Observed ring-like structures in protoplanetary disks are often interpreted as local pressure maxima, which induce efficient dust concentration. We revisit this paradigm, consideri…
Time-resolved protoplanetary disk physics in DQ Tau with JWST
Ã. Kóspál, P. Ãbrahám, V. V. Akimkin +17
Accretion variability is ubiquitous in YSOs. While large outbursts may strongly affect the disk, the effects of moderate bursts are less understood. We aim to study the physical re…
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…
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…
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…
C/O ratios in self-gravitating protoplanetary discs with dust evolution
Tamara Molyarova, Eduard Vorobyov, Vitaly Akimkin
Elemental abundances, particularly the C/O ratio, are seen as a way to connect the composition of planetary atmospheres with planet formation scenario and the disc chemical environ…
