GRAIL gravity observations of the transition from complex crater to peak-ring basin on the Moon: Implications for crustal structure and impact basin formation
High-resolution gravity data from the Gravity Recovery and Interior Laboratory (GRAIL) mission provide the opportunity to analyze the detailed gravity and crustal structure of impact features in the morphological transition from complex craters to peak-ring basins on the Moon. We calculate average radial profiles of free-air anomalies and Bouguer anomalies for peak-ring basins, protobasins, and...

متن کاملchallenges in defining of bouguer gravity anomaly
generally, gravity anomaly is the difference between the observed acceleration of earth's gravity and a normal value. topography (all masses above geoid) plays a main role in definition of the gravity anomaly. based on modeling of the effect of topography, there are different models of gravity anomaly such as free-air and bouguer anomaly. the main goal of the bouguer anomaly is removing of...
متن کاملOn restoring band-limited signals
The problem of reconstruction of band-limited signals from discrete and noisy data is studied. The reconstruction schemes employing cardinal expansions are proposed and their asymptotical properties are examined. In particular, the conditions for the convergence of the mean integrated squared errors are found and the rate of convergence is evaluated. The main difference between the proposed rec...
متن کاملSizes of Asteroids Responsible for Large Impact Basins on the Moon during the Late Heavy Bombardment
Introduction: Scaling relations derived from laboratory experiments and dimensional analysis [1] provide first-order estimates for the diameters of objects responsible for craters on the planets. At basin scales, however, the final crater rim may not be preserved due to rim collapse. Assumptions about impactor speed, angle, and density further preclude a unique determinations. As a result, the ...
