Interpretation of the Transit Light Curve in the Presence of Principal Main Minimum with Allowance for the Eccentricity of the Transit (Planet) Orbit

Abubekerov, M. K.; Gostev, N. Yu.

Using a high-precision algorithm for interpreting transit light curves in a model of a classical eclipsing binary star-exoplanet system, we studied the possibility of determining the system parameters in the absence of a priori knowledge of the orbital eccentricity. It was shown that it is impossible to determine the exact value of the eccentricit…

Determining the Structure of the Atmosphere Exoplanet HD 189733b Based on Multicolor Photometric Transit Observations

Bekesov, E. V.

In this paper, we analyze and interpret light curves obtained by observing with the HST telescope the transit of exoplanet HD 189733b across the disk of the star. Observations are carried out in a wide wavelength range of 5500–10 500 Å, which makes it possible to identify the relation between the wavelength and the data obtained during the interpr…

Modeling of the Exoplanet HAT-P-11b Magnetosphere

Alexeev, I. I.; Belenkaya, E. S.; Kalegaev, V. V.

The magnetospheric model of the HAT-P-11b magnetic field has been constructed based on the available data on the magnetic field of the star HAT-P-11 and its closest exoplanet HAT-P-11b, as well as the information on the stellar wind in this system. It has been shown how the magnitude and orientation of the interplanetary magnetic field control the…
