Analytical models for the
	comet plasma environment
Student: Noemi Vitos,

Supervisor:

Period: 2012-2013
 
Background
Rosetta is an ESA spacecraft, launched March 2, 2004 for arrival at its target comet in 2014. At the Swedish Institute of Space Physics in Uppsala, we have built an instrument called LAP (Langmuir probe) to study the ionized gas (plasma) close to the comet. For planning operations at the comet, and to interpret the data when we arrive, it is important to have models available for the plasma environment. The most advanced models are numerical, solving relevant physical equations on some grid around the comet. While detailed, such models require significant computer resources, and simplified analytical models are therefore also of interest. 
 
Project
The project includes: 
  - Reviewing the literature on comet plasma environment analytical models.
  
 
  - Collect relevant models into a simple code producing plots of 
	boundaries and parameters.
  
 
 
 
 
Examples of boundaries and structures in the plasma environment of a comet. Gathering
analytical models for such features and implementing them into a simple code is the
topic of this project. [Image credit:
