Planetary plasma measurement technology
地球与行星物理论评, 2021 Plasma is a key element of planetary environment, which is critical for understanding the planetary evolution history and mechanism. The plasma environment is related to the magnetic field and atmosphere status of the planet.

The evolution of planetary nebulae [PDF]
Astronomy & Astrophysics, 2010 By means of hydrodynamical models we do the first investigations of how the properties of planetary nebulae are affected by their metal content and what can be learned from spatially unresolved spectrograms of planetary nebulae in distant stellar systems.

Self Similar Shocks in Atmospheric Mass Loss Due to Planetary Collisions
Atmosphere, 2020 We present a mathematical model for the propagation of the shock waves that occur during planetary collisions. Such collisions are thought to occur during the formation of terrestrial planets, and they have the potential to erode the planet’s atmosphere.

Water, Life, and Planetary Geodynamical Evolution [PDF]
Space Science Reviews, 2007 In our search for life on other planets over the past decades, we have come to understand that the solid terrestrial planets provide much more than merely a substrate on which life may develop. Large-scale exchange of heat and volatile species between planetary interiors and hydrospheres/atmospheres, as well as the presence of a magnetic field, are ...
