Structure of the Stellar Neighborhood of CQ Tau in the Presence of a Companion in an Elongated Orbit
Tatiana Demidova
There are indirect signs of the presence of a companion near the star CQ\,Tau. A period of 10\;years was found in the brightness changes. The image of the disk shows an extensive c…
Simulation of a protoplanetary disk accretion activity due to a collision with a gas stream
Vitaliy Grigoryev, Tatiana Demidova
The consequences of a protoplanetary disk collision with a gas stream are being studied using three-dimensional numerical gas-dynamic simulation. The influence of orbital parameter…
Simulation of the Free Fall of a Gas Stream on a Protoplanetary Disk
Vitaliy Grigoryev, Tatiana Demidova
The problem of the formation of exoplanets in inclined orbits relative to the equatorial plane of the parent star or the main plane of the protoplanetary disk can be solved by intr…
Clumpy accretion as a possible reason of prolonged eclipses of UX~Ori type stars
Vladimir Grinin, Tatiana Demidova
The paper proposes a model of deep and prolonged eclipses of young stars of the UX~Ori type. Some of these events continue for decades and existing models cannot explain them. Our…
3-D SPH simulations of the FUOR flares in the clumpy accretion model
Tatiana V. Demidova, Vladimir P. Grinin
One of the early hypotheses about the origin of FUOR outbursts explains them by the fall of gas clumps from the remnants of protostellar clouds onto protoplanetary disks surroundin…
SPH simulations of structures in protoplanetary disks
Tatiana Demidova, Vladimir Grinin
The hydrodynamic models of the protoplanetary disk, which perturbed by the embeded low-mass companion, were calculated by our modification of GADGET-2 code. The cases of circular a…
