The c2d Spitzer spectroscopy survey of ices around low-mass young stellar objects, III: CH4
Karin I. Oberg, A. C. Adwin Boogert, Klaus M. Pontoppidan +4
CH4 is proposed to be the starting point of a rich organic chemistry. Solid CH4 abundances have previously been determined mostly toward high mass star forming regions. Spitzer/IRS…
The c2d Spitzer Spectroscopic Survey of Ices Around Low-Mass Young Stellar Objects: I. H2O and the 5-8 um Bands
A. Boogert, K. Pontoppidan, C. Knez +23
With the goal to study the physical and chemical evolution of ices in solar-mass systems, a spectral survey is conducted of a sample of 41 low luminosity YSOs using 3-38 um Spitzer…
Cold Disks: Spitzer Spectroscopy of Disks around Young Stars with Large Gaps
J. M. Brown, G. A. Blake, C. P. Dullemond +10
We have identified four circumstellar disks with a deficit of dust emission from their inner 15-50 AU. All four stars have F-G spectral type, and were uncovered as part of the Spit…
Probing Protoplanetary Disks with Silicate Emission: Where is the silicate emission zone?
J. E. Kessler-Silacci, C. P. Dullemond, J. -C. Augereau +6
Recent results indicate that the grain size and crystallinity inferred from observations of silicate features may be correlated with spectral type of the central star and/or disk g…
