Tomo-V -- a New Tool for Doppler Tomography
P. V. Kaygorodov
In this paper, a new tool for Doppler tomography, Tomo-V (https://tomo-v.inasan.ru) that is developed based on the algebraic reconstruction technique (ART) has been presented. Prev…
On Systematic Errors in Cross-Identification of Binary Stars in Gaia
E. Malik, P. Kaigorodov, D. Kovaleva +1
Using Gaia DR3 data, binary star catalogs have been created containing information on a total of more than 2.6 million pairs. This increases by more than an order of magnitude the…
On one effect of coronal mass ejections influence on the envelopes of hot Jupiters
A. G. Zhilkin, D. V. Bisikalo, P. V. Kaigorodov
It is now established that the hot Jupiters have extensive gaseous (ionospheric) envelopes, which expanding far beyond the Roche lobe. The envelopes are weakly bound to the planet…
Mass-Loss Rates of "Hot-Jupiter" Exoplanets with Various Types of Gaseous Envelopes
A. A. Cherenkov, D. V. Bisikalo, P. V. Kaigorodov
According to the computations results obtained by Bisikalo et al. (2013b) for the gas-dynamical effect of stellar winds on exoplanet atmospheres, three types of gaseous envelopes c…
Types of Gaseous Envelopes of "Hot Jupiter" Exoplanets
D. V. Bisikalo, P. V. Kaigorodov, D. E. Ionov +1
As a rule, the orbital velocities of "hot Jupiters," i.e., exoplanets with masses comparable to the mass of Jupiter and orbital semi-major axes less than 0.1 AU, are supersonic rel…
Morphology of the Interaction Between the Stream and Cool Accretion Disk in a Semi-detached Binary Systems
D. V. Bisikalo, A. A. Boyarchuk, P. V. Kaygorodov +1
We analyze heating and cooling processes in accretion disks in binaries. For realistic parameters of the accretion disks in close binaries (with accretion rates from 1e-12 to 1e-7…
Reverse Rotation of the Accretion Disk in RW Aur A: Observations and a Physical Model
D. V. Bisikalo, A. V. Dodin, P. V. Kaygorodov +3
Speckle interferometry of the young binary system RW Aur was performed with the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences using filt…
