    • Delayed formation of the equatorial ridge on Iapetus from a subsatellite created in a giant impact 

      Dombard, Andrew J.; Cheng, Andrew F.; McKinnon, William B.; Kay, Jonathan P. (American Geophysical Union, 2012-03)
      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 of Iapetus, and explaining its ...
    • Flanking Fractures and the Formation of Double Ridges on Europa 

      Patterson, G. Wesley; Lederer, Adam P.; Prockter, Louise M.; Dombard, Andrew J. (Elsevier, 2013-03)
      Europa, a satellite of Jupiter, is one of the most intriguing worlds in the solar system. Its dearth of impact craters and plethora of surface morphologies point to a dynamic evolution of its icy shell in geologically ...
    • Impact basin relaxation on Rhea and Iapetus and relation to past heat flow 

      White, Oliver L.; Schenk, Paul M.; Dombard, Andrew J. (Elsevier, 2013-04)
      Evidence for relaxation of impact crater topography has been observed on many icy satellites, including those of Saturn, and the magnitude of relaxation can be related to past heat flow (e.g. Moore, J.M., Schenk, P.M., ...
    • On the origin of mascon basins on the Moon (and beyond) 

      Dombard, Andrew J.; Hauck, Steven A.; Balcerski, Jeffrey A. (American Geophysical Union, 2013-01)
      Mascon basins on the Moon are large craters that display significant positive free-air and Bouguer gravity anomalies. An important question is why is not every large crater a mascon, as less than half have been previously ...
