Clumpy accretion in pre-main-sequence stars as a source of perturbations in circumstellar disks
Tatiana V. Demidova, Vladimir P. Grinin
The development of perturbations in the circumstellar disks of pre-main-sequence stars caused by clumpy accretion was investigated. Here we perform 3D hydrodynamical smoothed parti…
Catastrophic events in protoplanetary disks and their observational manifestations
Tatiana V. Demidova, Vladimir P. Grinin
Observations of protoplanetary disks with high angular resolution using an ALMA interferometer showed that ring-shaped structures are often visible in their images, indicating stro…
Three-lane and multi-lane signatures of planets in planetesimal disks
Tatiana V. Demidova, Ivan I. Shevchenko
In massive numerical experiments we show that a planet embedded in a planetesimal disk induces a characteristic multi-lane "planetosignature" representing a pattern of several stel…
Structures in circumbinary disks: Prospects for observability
Jan Philipp Ruge, Sebastian Wolf, Tatiana Demidova +1
During the past decade circumbinary disks have been discovered around various young binary stars. Hydrodynamical calculations indicate that the gravitational interaction between th…
Spiral patterns in planetesimal circumbinary disks
Tatiana V. Demidova, Ivan I. Shevchenko
Planet formation scenarios and the observed planetary dynamics in binaries pose a number of theoretical challenges, especially in what concerns circumbinary planetary systems. We e…
Modulation of Circumstellar Extinction in a Young Binary System with a Low-Mass Companion in a Noncoplanar Orbit
V. P. Grinin, T. V. Demidova, N. Ya. Sotnikova
The cyclic activity model of a young star with the low-mass secondary component (q = M2/M1 <= 0.1) accreting a matter from circumbinary disk is considered. It is assumed that the o…
