Saturn's ringlets
The moon - Tập 26 - Trang 97-100 - 1982
J. A. Bastin, D. H. Smith
This paper suggests that Saturn's magnetic field is, in part, responsible for the very fine-scale radial features, or ringlets, seen in the ring-system. The planet's dipole field interacts with slight radial variations in plasma density, and the operation of an instability segregates the magnetic flux and plasma in the ring-plane into narrow alternating zones. We suggest that this mechanism may ac...... hiện toàn bộ
Evolutionary tracks of the terrestrial planets
The moon - Tập 39 - Trang 207-214 - 1987
Takafumi Matsui, Yutaka Abe
On the basis of the model proposed by Matsui and Abe, we will show that two major factors — distance from the Sun and the efficiency of retention of accretional energy — control the early evolution of the terrestrial planets. A diagram of accretional energy versus the optical depth of a proto-atmosphere provides a means to follow the evolutionary track of surface temperature of the terrestrial pla...... hiện toàn bộ
Criteria for the detection of lunar cryptomaria
The moon - Tập 69 - Trang 141-172 - 1995
Irene Antonenko, James W. Head, John F. Mustard, B. Ray Hawke
Cryptomaria are mare basalt deposits hidden or obscured by superposed higher albedo material or variations in albedo. They represent a record of the earliest mare volcanism, and may be a significant volumetric contribution to the volcanic and magmatic history of the Moon. In order to assess their global distribution and significance, criteria for the identification of cryptomaria are developed and...... hiện toàn bộ
Formation of a ‘magma ocean’ on the terrestrial planets due to the blanketing effect of an impact-induced atmosphere
The moon - Tập 34 Số 3 - Trang 223-230 - 1986
Takafumi Matsui, Yutaka Abe
Eulerian libration points of restricted problem of three oblate spheroids
The moon - Tập 63 - Trang 23-28 - 1993
S. M. El-Shaboury, M. A. El-Tantawy
In this paper we consider the circular restricted problem of three oblate spheroids. The collinear equilibrium solutions are obtained. Finally a numerical study of the influence of the non-sphericity in the location of the libration points is made.
The expansion of negative powers of the mutual distance between two planets
The moon - Tập 43 - Trang 197-200 - 1988
Osman M. Kamel, Adel S. Soliman
An outline of a new method is given to obtain the expansion of δ−S by the method of W. M. Smart, using Taylor theorem and neglecting powers higher than the fourth in the eccentricity and inclination.

Morphometric Characterization and Reconstruction Effect Among Lunar Impact Craters
The moon - Tập 111 - Trang 139-155 - 2014
Weiming Cheng, Jiao Wang, Cong Wan
Impact craters on the lunar surface have a variety of morphometric characteristics that are very useful in understanding the evolutionary history of lunar landscape morphologies. Based on digital elevation model data and photographs from China’s Chang’E-1 lunar orbiter, we develop morphologic parameters and quantitative methods for presenting the morphometric characteristics of impact craters, an...... hiện toàn bộ
