Saturn's Exploration Beyond Cassini-Huygens [PDF]
, 2009 For its beautiful rings, active atmosphere and mysterious magnetic field, Saturn is a fascinating planet. It also holds some of the keys to understanding the formation of our Solar System and the evolution of giant planets in general.

Results from a set of three-dimensional numerical experiments of a hot Jupiter atmosphere [PDF]
, 2013 We present highlights from a large set of simulations of a hot Jupiter atmosphere, nominally based on HD 209458b, aimed at exploring both the evolution of the deep atmosphere, and the acceleration of the zonal flow or jet.

ATMOSPHERIC SULFUR PHOTOCHEMISTRY ON HOT JUPITERS [PDF]
The Astrophysical Journal, 2009 We develop a new 1D photochemical kinetics code to address stratospheric chemistry and stratospheric heating in hot Jupiters. Here we address optically active S-containing species and CO2 at 1200 < T < 2000 K. HS (mercapto) and S2 are highly reactive species that are generated photochemically and thermochemically from H2S with peak abundances ...

Three-dimensional modeling of lightning-induced electromagnetic pulses on Venus, Jupiter and Saturn
, 2018 While lightning activity in Venus is still controversial, its existence in Jupiter and Saturn was first detected by the Voyager missions and later on confirmed by Cassini and New Horizons optical recordings in the case of Jupiter, and recently by Cassini

Management decision support algorithm for autonomous spacecraft’s control in the planet’s atmosphere
RUDN Journal of Engineering Research, 2023 A new algorithm for making autonomous decisions when controlling spacecraft carrying out descent in the atmosphere is developed, which allows to carry out stable control of the spacecraft relative to the nominal flight trajectories, which provide to ...

ATMOSPHERIC HEAT REDISTRIBUTION ON HOT JUPITERS [PDF]
The Astrophysical Journal, 2013 Infrared lightcurves of transiting hot Jupiters present a trend in which the atmospheres of the hottest planets are less efficient at redistributing the stellar energy absorbed on their daysides---and thus have a larger day-night temperature contrast---than colder planets.

Nebular water depletion as the cause of Jupiter's low oxygen abundance
, 2012 Motivated by recent spectroscopic observations suggesting that atmospheres of some extrasolar giant-planets are carbon-rich, i.e. carbon/oxygen ratio (C/O) $\ge$ 1, we find that the whole set of compositional data for Jupiter is consistent with the ...

Influence of stellar variability on the determination of the radius during a transit of an exoplanet
EPJ Web of Conferences, 2011 Stellar variability can affect the estimate of an exoplanet radius measured during a transit. We developed a transit light curve model which includes stellar spots.
