Estimates of Densities and Filling Factors from a Cooling Time Analysis of Solar Microflares Observed with RHESSI
Estimates Densities Filling Factors Solar Microflares
2011/10/12
We use more than 4,500 microflares from the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) microflare data set (Christe et al., 2008, Ap. J., 677, 1385) to estimate electron densities a...
A Correlation Between Surface Densities of Young Stellar Objects and Gas in Eight Nearby Molecular Clouds
Stellar Objects Gas Nearby Molecular Clouds
2011/9/28
We report the discovery and characterization of a power law correlation between the local surface densities of Spitzer-identified, dusty young stellar objects and the column density of gas (as traced ...
Estimation of C II and C II* column densities along Galactic sight-lines
ine profiles – ISM clouds – ISM abundances – ultraviolet ISM
2010/11/10
We present interstellar Cii (1334.5323°A) and Cii ∗ (1335.7077°A)column density measurements along 14 Galactic sight-lines. These sight-lines sample a variety of Galactic disk environments and i...
