When NASA’s 990-pound Dragonfly rotorcraft reaches the Selk crater region – the mission’s target touchdown spot – on Saturn’s moon Titan in 2034, Cornell’s Léa Bonnefoy '15 will have helped to make it...
Swirling around the planet’s equator, the rings of Saturn are a dead giveaway that the planet is spinning at a tilt. The belted giant rotates at a 26.7-degree angle relative to the plane in which it o...
AN ANALYTIC PARAMETERIZATION OF SELF-GRAVITY WAKES IN SATURN’S RINGS, WITH APPLICATION TO OCCULTATIONS AND PROPELLERS
planets and satellites individual (Saturn)–planets and satellites rings
2015/12/25
We have developed a semianalytic method of parameterizing N-body simulations of self-gravity wakes in Saturn’s rings, describing their photometric properties by means of only six numbers: three optica...
THE "SWARM" MODEL FOR THE AZIMUTHAL BRIGHTNESS VARIATIONS IN SATURN'S RING A
Saturn's rings. Photometry observation ring system The image calibration
2014/12/10
A number of researchers have observed asymmetric azimuthal variations in Saturn's ring A not seen in any other portion of the rings. In order to explore this effect, photometric observations of the ri...
Two phase, inward-then-outward migration of Jupiter and Saturn in the gaseous Solar Nebula
accretion, accretion disks – planets and satellites: formation – hydrodynamics – methods: numerical
2011/10/20
It has recently been shown that the terrestrial planets and asteroid belt can be reproduced if the giant planets underwent an inward-then-outward migration (the "Grand Tack"; Walsh et al 2011). Inward...
Considerations on the accretion of Uranus and Neptune by mutual collisions of planetary embryos in the vicinity of Jupiter and Saturn
planetary systems – planets and satellites: formation – planets and satellites: individual: Uranus, Neptune – protoplanetary disks
2011/10/8
Modeling the formation of Uranus and Neptune is a long-lasting problem in planetary science. Due to the gas-drag, collisional damping, and resonant shepherding, the planetary embryos repel the planete...
Searching for Saturn's Dust Swarm: Limits on the size distribution of Irregular Satellites from km to micron sizes
Solar System: satellites
2011/10/8
We describe a search for dust created in collisions between the Saturnian irregular satellites using archival \emph{Spitzer} MIPS observations. Although we detected a degree scale Saturn-centric exces...
HD 46375: seismic and spectropolarimetric analysis of a young Sun hosting a Saturn-like planet
seismic spectropolarimetric analysis Saturn-like planet
2010/11/15
Context. HD 46375 is known to host a Saturn-like exoplanet orbiting at 0.04 AU from its host star. Stellar light reflected by the planet was tentatively identified in the 34-day CoRoT run acquired in ...
Contribution of amateur observations to Saturn storm studies
Contribution of amateur observations Saturn storm studies
2010/11/11
Since 2004, Saturn Electrostatic Discharges (SEDs),which are the radio signatures of lightning in Saturn’s atmosphere, have been observed by the Cassini Radio and Plasma Wave Science instrument (RPWS)...
A sub-Saturn Mass Planet, MOA-2009-BLG-319Lb
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/28
We report the gravitational microlensing discovery of a sub-Saturn mass planet, MOA-2009-BLG-319Lb, orbiting a K or M-dwarf star in the inner Galactic disk or Galactic bulge. The high cadence observat...
Flash: NASA's Cassini Spacecraft Sees Lightning On Saturn
NASA's Cassini Spacecraft Saturn
2010/4/29
NASA's Cassini spacecraft has captured images of lightning on Saturn. The images have allowed scientists to create the first movie showing lightning flashing on another planet.After waiting years for ...
NASA Space Telescope Discovers Largest Ring Around Saturn
NASA Space Telescope Largest Ring Saturn
2009/10/10
NASA's Spitzer Space Telescope has discovered an enormous ring around Saturn -- by far the largest of the giant planet's many rings.The new belt lies at the far reaches of the Saturnian system, with ...
Wind estimate ‘shortens Saturn’s day by five minutes’（图）
shortens Saturn’s day wind five minutes’
2009/8/3
A new way of detecting how fast large gaseous planets are rotating suggests Saturn’s day lasts 10 hours, 34 minutes and 13 seconds – over five minutes shorter than previous estimates that were based o...
Feb 02, 2007，A recent study has changed our understanding of planetary atmospheres and may have implications for understanding the future of our own planet's climate. How Earth's environment changes o...
