SOFIA/upGREAT far-infrared spectroscopy of bright rimmed pillars in IC 1848
Dariusz C. Lis, Rolf Güsten, Paul F. Goldsmith +4
Using the upGREAT instrument on SOFIA, we have imaged the [C II] 158 μm fine structure line emission in bright-rimmed pillars located at the southern edge of the IC1848 H II region…

Retrievals of Protoplanetary Disk Parameters using Thermochemical Models: I. Disk Gas Mass from Hydrogen Deuteride Spectroscopy
Young Min Seo, Karen Willacy, Geoffrey Bryden +4
We discuss statistical relationships between the mass of protoplanetary disks and the hydrogen deuteride (HD) line emission and the dust spectral energy distribution (SED) determin…
