2. The Large Magellanic Cloud's Largest Molecular Cloud Complex: Spitzer Analysis
We present a mid-infrared analysis of star-formation activity in the Large Magellanic Cloud's molecular ridge (south of 30 Doradus). The Magellanic Clouds are a rare laboratory in which extragalactic star-formation diagnostics can be tested at high spatial resolution. ... Detailed analysis in very nearby galaxies, like the Magellanic Clouds, allows us to test and better understand the scaling relations used in unresolved and distant star-formation regions. ...

9. The Electron Pressure Differential between the Sunspot Plume and the
... It was shown in the early 1980's that spectral lines formed around 1-2.5 x 10 5 K were enhanced in radiance by factors up to 15-25 over the normal quiet Sun. From the dynamical viewpoint, this would suggest a pressure imbalance between the sunspot and the surrounding region. ... Here, the electron density was evaluated over a bright sunspot plume region using lines within the O V 760? multiplet. ... The derived densities in all four regions are indicated. ...
