PROBING STELLAR ACCRETION WITH MID-INFRARED HYDROGEN LINES
PROBING STELLAR ACCRETION WITH MID-INFRARED HYDROGEN LINES
In this paper we investigate the origin of the mid-infrared (IR) hydrogen recombination lines for a sample of 114 disks in different evolutionary stages (full, transitional and debris disks) collected from the {\it Spitzer} archive. We focus on the two brighter {H~{\sc i}} lines observed in the {\it Spitzer} spectra, …
