Homework Statement
I have a project in my school where we have to write a presentation on a research paper that we find. I picked this article: http://arxiv.org/PS_cache/arxiv/pdf/1003/1003.0416v1.pdf and they start talking about how they find abundances in the nebulae using electron temperature and electron densities. I have no prior knowledge to any astronomy or astrophysics and so not only do i not really know what these two things are but i also don't know how they are used to calculate abundances. Any help i can get in understanding these things would be greatly apreciated. Thanks
