Mercury’s Interior Structure, Rotation, and Tides
Space Science Reviews, 2007This review addresses the deep interior structure of Mercury. Mercury is thought to consist of similar chemical reservoirs (core, mantle, crust) as the other terrestrial planets, but with a relatively much larger core. Constraints on Mercury’s composition and internal structure are reviewed, and possible interior models are described. Large advances in

Icarus, 1975
Critical measurements relative to interior structure which can be made during a spacecraft mission to Uranus are discussed. Models of atmospheric composition, possible magnetic moment, and gravitational harmonics are described, and it is shown that high quality imaging of the atmospheric rotation and determination of the possible magnetic field ...

Structure of the Earth’s Interior
1985The study of the Earth’s interior can be approached in two ways: (1) Either by considering the Earth as a part of the Solar System and deducing indirectly such factors as its speed of rotation, density and mass (all of which falls within the domain of astronomy).

Nature, 1969
MUCH has been written about the solar neutrino experiment of R. Davis, jun.1. In this experiment, the counting rate expected from boron 8 (8B) solar neutrinos2 was an order of magnitude greater than the experimental background counting rate—but only the background counting rate was obtained3.

Solar interior structure and luminosity variations
Solar Physics, 1981The assumptions of standard solar evolution theory are mentioned briefly, and the principle conclusions drawn from them are described. The result is a rationalization of the present luminosity and radius of the Sun. Because there is some uncertainty about the interior composition of the Sun, a range of models is apparently acceptable.

Probing the Interior Structure of Venus
2015The formation, evolution, and structure of Venus remain a mystery more than 50 years after the first visit by a robotic spacecraft. Radar images have revealed a surface that is much younger than those of the Moon, Mercury, and Mars as well as a variety of enigmatic volcanic and tectonic features quite unlike those we are familiar with on Earth.

Seismicity and interior structure of the Moon
2015The beginning of the seismological inv estigation of the Moon dates back to the beginning of space flight: A working group implemented by NASA in 1959 (Hall, 1977) suggested the development of a seismometer for a hard landing on the Moon. This resulted in Ranger missions 3 to 5, which all unfortunately failed for technical reasons (Hall, 1977).
