    A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. laboratory studies and theoretical models detailed observations of planetary shapes - moon with atmosphere orbiting jovian planet 1 AU from 1 Msun star Unlikely It kicked out many comets from the inner solar system through gravitational encounters, thus limiting the number of objects that could potentially hit the inner planets.

    Many of the larger planetary satellites, selected asteroids, and comets have also been observed. These data provide important information regarding the atmospheres and surfaces of solar system objects and the processes shaping their compositions. The COSPAR publication Advances in Space Research (ASR) is an open journal covering all areas of space research including: space studies of the Earth's surface, meteorology, climate, the Earth-Moon system, planets and small bodies of the solar system, upper atmospheres, ionospheres and magnetospheres of the Earth and planets including reference atmospheres, space plasmas in the .

    Earth as an Evolving Planetary System, Third Edition, examines the various subsystems that play a role in the evolution of the Earth, including subsystems in the crust, mantle, core, atmosphere, oceans, and life. This third edition includes 30% new material and, for the first time, includes full color images in both the print and electronic. Unfortunately, this book can't be printed from the OpenBook.

This is the fifth semi-annual progress report describing research on dissociative recombination reactions in planetary and comet atmospheres. The Appendix has two papers that describe NASA supported research. Both papers have been recently accepted for : Steven L.

Guberman. Dissociative recombination (DR) reactions in planetary and comet atmospheres are discussed. A computer program was developed which determines DR cross sections and rates using potential curves and electronic capture widths.

It uses Multi-Channel Quantum Defect Theory (MQDT) to include excited Rydberg resonance levels in the DR cross section and rate calculations. Current efforts have focused on the dissociative recombination (DR) of O2(+), a process of great importance in planetary atmospheres.

This process is difficult to study experimentally because of the need to determine the dependence of the product electronic states and kinetic energies upon the vibrational distribution of the ion and electron temperature.

These ideas are illustrated with the new results for DR from excited ion vibrational levels of O2(+) into the dissociative state which leads to O(1S) + O(1D).

The Atmospheres of the Terrestrial Planets. How did the terrestrial planets get their atmospheres. Two distinctly different processes exist for the formation and development of the atmosphere of a terrestrial planet.

The first is capture of a primitive, or primary, atmosphere. The second is the outgassing of a secondary atmosphere. The sun is orbited by many comets; every time a comet passes close to the sun, the ices in the comet boil off, creating many particles in almost the same orbit as the main comet.

Over time, the path of the comet is littered with these small particles - most are as fine as sand grains.In the case of O: the cross section for excitation of the v=1 ion level has a.

sudden onset at the energy of the v-1 level, OeV.
