Veiling of Photosphere Lines in the Spectra of UX ORI Stars at Deep Light Minima. I. The Star RR Tau

P. O. Dimitrieva, L. V. Tambovtseva, V. P. Grinin

The spectra of RR Tau star, which belongs to the family of young irregular variable UX Ori type stars, in its different brightness states have been studied using a comparative anal…

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…

UX Ori Stars Eclipses by Large-Scale Disc Perturbations

S. G. Shulman, V. P. Grinin

We simulate the polarized radiative transfer in vicinities of the UX Ori type stars during their minima. Our model of an eclipse by an extended disc perturbation generalizes the co…

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…

On the nature of the azimuthal asymmetry of protoplanetary disks observed pole-on. The case LkHa 101

Tatiana Demidova, Vladimir Grinin

The model of a protoplanetary disk of a star with a low-mass companion (), moving on a circular orbit, which slightly inclined to the disk plane ()…

Asymmetric Illumination of a Circumbinary Disk in the Presence of a Low-Mass Companion

T. Demidova, V. Grinin, N. Sotnikova

The model of an young star with a protoplanetary disk and a low-mass companion, which is moving on a circular orbit, inclined to the disk plane, is considered. The hydrodynamic mod…

An active asteroid belt causing the UX Ori phenomenon in RZ Psc

W. J. de Wit, V. P. Grinin, I. S. Potravnov +3

We report the discovery of mid-infrared excess emission in the young object RZ Psc. The excess constitutes ~8% of its Lbol, and is well fit by a single 500K black-body implying a d…
