Iapetus Revealed The striking appearance of Saturn's moon Iapetus—half black and half white—has puzzled astronomers for over three centuries. Now Spencer and Denk (p. 432, published online 10 December) present an explanation for this asymmetry: A thermally controlled runaway migration of water ice triggered by exogenic deposition of dark material on the moon's leading darker side, which faces the direction of motion of the moon in its orbit around Saturn. This mechanism is unique to Iapetus… Expand

Iapetus: Unique Surface Properties and a Global Color Dichotomy from Cassini Imaging
TLDR
Thermal migration of water ice explains the observed color asymmetry of Saturn’s unusual moon, Iapetus, and reveals a global color dichotomy, wherein both dark and bright materials on the leading side have a substantially redder color than the respective trailing-side materials. Expand
Finding the trigger to Iapetus' odd global albedo pattern: Dynamics of dust from Saturn's irregular satellites
Abstract The leading face of Saturn’s moon Iapetus, Cassini Regio, has an albedo only one tenth that on its trailing side. The origin of this enigmatic dichotomy has been debated for over 40 years,Expand
Sublimation's impact on temporal change of albedo dichotomy on Iapetus
Abstract Iapetus, one of the saturnian moons, has an extreme albedo contrast between the leading and trailing hemispheres. The origin of this albedo dichotomy has led to several hypotheses, howeverExpand
Probing the subsurface of the two faces of Iapetus
Saturn's moon Iapetus, which is in synchronous rotation, is covered by an optically dark material mainly on its leading side, while its trailing side is significantly brighter. Because longerExpand
The rapid formation of Sputnik Planitia early in Pluto ’ s history
Pluto’s Sputnik Planitia is a bright, roughly circular feature that resembles a polar ice cap. It is approximately 1,000 kilometres across and is centred on a latitude of 25 degrees north and aExpand
The rapid formation of Sputnik Planitia early in Pluto’s history
TLDR
Modelling suggests that Sputnik Planitia formed shortly after Charon did and has been stable, albeit gradually losing volume, over the age of the Solar System. Expand
The surface composition of Iapetus: Mapping results from Cassini VIMS
Abstract Cassini VIMS has obtained spatially resolved imaging spectroscopy data on numerous satellites of Saturn. A very close fly-by of Iapetus on September 10, 2007 provided the best data on theExpand
Delayed formation of the equatorial ridge on Iapetus from a subsatellite created in a giant impact
[1] The great equatorial ridge on Saturn's moon Iapetus is arguably the most perplexing landform in the solar system. The ridge is a mountain range up to 20 km tall and sitting on the equator ofExpand
Formation of the bulge of Iapetus through long-wavelength folding of the lithosphere
Abstract Previous models that attempted to explain the formation of the pronounced oblate shape of Iapetus suggested that it was a preserved rotational bulge. These models found that heating wasExpand
Infrared spectroscopic characterization of the low-albedo materials on Iapetus
Abstract Iapetus, one of the large satellites of Saturn, has been studied over the centuries for its signature brightness contrast, light on one side and dark on the opposite. It has recently beenExpand

Cometary collisions and the dark material on Iapetus
Iapetus (S8) is unique in our solar system in that the albedo of its leading hemisphere is only 0.05 while that of the trailing side is 0.5. Several existing hypotheses are examined and foundExpand
Albedo asymmetry of Iapetus

Abstract Telescopic observations, laboratory simulations, and photogeological studies have been conducted to investigate the composition of the dark material on Iapetus and the reasons for itsExpand
An explanation of the light curve of Iapetus
Abstract This paper seeks a simple explanation for the large-amplitude (∼ 2 mag) periodic light curve of Saturn's satellite Iapetus, which, as the light curve shows, apparently rotates synchronously.Expand
