Observations of UX Ori in deep minima with the Nordic Optical Telescope. I. Analysis of spectral lines
L. V. Tambovtseva, A. A. Djupvik, V. P. Grinin +11
UX Orionis stars are the most active young stars; they undergo sporadic fadings of 2 - 4 magnitudes in the V-band, due to variable circumstellar extinction caused by a nearly edge-…
Modelling UX Ori Star Eclipses based on Spectral Observations with the Nordic Optical Telescope. I. RR Tau
V. P. Grinin, L. V. Tambovtseva, A. A. Djupvik +12
Based on observations obtained with the Nordic Optical Telescope we investigate the spectral variability of the Herbig Ae star RR Tau. This star belongs to the UX Ori family, chara…
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…
Photometric activity of CQ Tau on the time interval of 125 years
V. P. Grinin, L. V. Tambovtseva, O. Yu. Barsunova +1
The star CQ Tau belongs to the family of UX Ori type stars. It has very complex photometric behavior and complex structure of the circumstellar environment. In our paper we constru…
Magnetospheric accretion at the late phases of the Pre-Main-Sequence evolution. The case of RZ Psc
D. V. Dmitriev, V. P. Grinin, I. S. Potravnov +1
It has been shown that during the outburst of accretion activity observed in UX Ori type star RZ Psc in 2013, the accretion rate increased approximately by an order of magnitude. T…
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…
