Seasons on Saturn. I. Changes in reflecting characteristics of the atmosphere at 1964–2012
Вісник Астрономічної школи, 2015 Due to considerable tilting of the equator to the orbital plane, presence of rings and elongation of the orbit around the Sun, Saturn is strongly affected by seasonal changes in the solar radiation influx. Such change of the mode of irradiation of Saturn'

A Gap-sharing Planet Pair Shaping the Crescent in HD 163296: A Disk Sculpted by a Resonant Chain
The Astrophysical Journal Letters, 2023 The Atacama Large Millimeter Array observations of the disk around HD 163296 have resolved a crescent-shape substructure at around 55 au, inside and off-center from a gap in the dust that extends from 38 to 62 au.

JHEP 0705:050,2007, 2007 Using the inverse scattering method we construct an exact stationary asymptotically flat 4+1-dimensional vacuum solution describing Black Saturn: a spherical black hole surrounded by a black ring. Angular momentum keeps the configuration in equilibrium.

Rotation Reduces Convective Mixing in Jupiter and Other Gas Giants
The Astrophysical Journal Letters, 2023 Recent measurements of Jupiter’s gravitational moments by the Juno spacecraft and seismology of Saturn’s rings suggest that the primordial composition gradients in the deep interior of these planets have persisted since their formation.

The Composition of Saturn's Rings [PDF]
Icarus, 2002 Abstract A composite spectrum between 0.30 and 4.05 μm of Saturn's rings is analyzed using the Shkuratov scattering theory (Shkuratov et al. 1999, Icarus 137 , 235–246). Several types of surface and composition are discussed. We demonstrate that both the strong reddening over the interval 0.3–0.7 μm and the water ice absorption features are well ...

Seasons on Saturn. II. Influence of solar activity on variation of methane absorption
Вісник Астрономічної школи, 2015 Methane and ammonia in the atmosphere of Saturn are in the form of impurities at the level of less than tenths of a percentage. They take part in photochemical processes, the main products of which are hydrocarbons and ammonia NH_3. Polyacetylenes absorb

Corotation-driven magnetosphere-ionosphere coupling currents in Saturn’s magnetosphere and their relation to the auroras [PDF]
Annales Geophysicae, 2003 We calculate the latitude profile of the equatorward-directed ionospheric Pedersen currents that are driven in Saturn’s ionosphere by partial corotation of the magnetospheric plasma.

Nature, 1884 IN the interesting account of the observations of Messrs. Henry on the rings of Saturn (NATURE, May 29, p. 105) they seem to consider the bright ring they then saw as new. On looking over my note-book I find I observed indications of such a bright ring extending inwards as far as the limb of ball. The exact words are, “I see a brighter line here,” with
