Dipole structure of planetary atoms

Physical Review Letters, 1992
Using resonant multiphoton laser excitation in combination with temporarily applied electric fields we have excited high-lying planetary states in strontium. Thereby, the angular momenta were high enough to prevent penetration of the ${\mathrm{Sr}}^{++}$ core, as well as the mutual penetration of the two excited wave functions. Analysis of the spectra (

Peripheral Structures of Planetary Systems

Solar System Research, 2004
We analyze the conditions for the formation and time evolution of peripheral comet structures of solar-type planetary systems. In the Solar system, these include the Kuiper belt, the Oort cloud, the comet spear, and the Galactic comet ring that marks the Galactic orbit of the Sun. We consider the role of the viscosity of a protoplanetary gas–dust disk,

Interior Structure, Planetary

2011
Models of the interior structure of a ▶ planet or ▶ satellite give the variations of thermodynamic state variables as functions of radius (starting at the center) or depth (starting at the surface). The thermodynamic state variables are pressure, temperature, density (or specific volume), and the concentration of chemical species.
