Time-resolved protoplanetary disk physics in DQ Tau with JWST
Á. Kóspál, P. Ábrahám, 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…
Observational Chemical Signatures of the Past FU Ori Outbursts
Lis Zwicky, Tamara Molyarova, Vitaly Akimkin +4
FU Ori-type stars are young stellar objects (YSOs) experiencing luminosity outbursts by a few orders of magnitude, which last for years. A dozen of FUors are known up…
A resolved rotating disk wind from a young T Tauri star in the Bok globule CB26
R. Launhardt, Ya. N. Pavlyuchenkov, V. V. Akimkin +9
The disk-outflow connection plays a key role in extracting excess angular momentum from a forming protostar. We have previously reported the discovery of a small molecular outflow…
Coagulation-Fragmentation Equilibrium for Charged Dust: Abundance of Submicron Grains Increases Dramatically in Protoplanetary Disks
Vitaly Akimkin, Alexei V. Ivlev, Paola Caselli +2
Dust coagulation in protoplanetary disks is not straightforward and is subject to several slow-down mechanisms, such as bouncing, fragmentation and radial drift to the star. Furthe…
The Young Binary DQ Tau Produces Another X-ray Flare Near Periastron
Konstantin V. Getman, Vitaly V. Akimkin, Nicole Arulanantham +4
This work is part of a multi-wavelength program to study the effects of X-ray/UV/optical stellar radiation on the chemistry of the circumbinary disk around the young high-eccentric…
Gravitoviscous protoplanetary disks with a dust component. II. Spatial distribution and growth of dust in a clumpy disk
Eduard I. Vorobyov, Vardan G. Elbakyan
Spatial distribution and growth of dust in a clumpy protoplanetary disk subject to vigorous gravitational instability and fragmentation is studied numerically with sub-au resolutio…
