... 2015 January 21 . The Complex Ion Tail of Comet Lovejoy . ... As the name implies, the ion tail is made of ionized gas -- gas energized by ultraviolet light from the Sun and pushed outward by the solar wind . ... The effect of the variable solar wind combined with different gas jets venting from the comet's nucleus accounts for the tail's complex structure. Following the wind, structure in Comet Lovejoy's tail can be seen to move outward from the Sun even alter its wavy appearance over time. ...

... My thesis aims to understand the energetics and composition of the jet near its origin, and its interaction with the ICM , focusing on detailed models of the inner structure of a spectacular radio source Hydra A. The key features of my modelling are that 1) I identify the four bright knots in the northern jet of Hydra A as biconical reconfinement shocks, which result when an over-pressured jet starts to come into equilibrium whit the galactic ...

Your Phase II Proposal and Using RPS2 . ... Perhaps the single most important thing to bear in mind when you look at your RPS2 output for a GHRS program is that RPS2 assumes your observations fall into tidy orbits with a nominal observing period and without being interrupted by the South Atlantic Anomaly (SAA). ... In some programs requiring very high wavelength precision you will not want to have your exposures interrupted by SAA passage or earth occultation because that time delay adds uncertainty. ...

spaceweb@oulu.fi - last update: 20 September 1998, 2020 UT (RR) . Traveling Convection Vortex (TCV) is a name given to a specific type of daytime magnetic impulsive events observed by high-latitude ground-based magnetometer arrays. Since the most likely source for TCVs is the solar wind , they are considered to be important processes in transfering energy from the solar wind into the magnetosphere . ... For example, one AMPTE Lithium release in the solar wind caused a TCV event . ...
