VLT-ISAAC 3-5 micron spectroscopy of embedded young low-mass stars. III. Intermediate-mass sources in Vela
W. F. Thi, E. F. van Dishoeck, E. Dartois +5
We performed a spectroscopic survey toward five intermediate-mass class I YSOs located in the Southern Vela molecular cloud in the L and M bands at resolving powers 600-800 up to 1…
Mapping ices in protostellar environments on 1000 AU scales: Methanol-rich ice in the envelope of Serpens SMM 4
K. M. Pontoppidan, E. F. van Dishoeck, E. Dartois
We present VLT-ISAAC L-band spectroscopy toward 10 stars in SVS 4, a 30"x45" dense cluster of pre-main sequence stars deeply embedded in the Serpens star forming cloud. The ISAAC s…
Organic matter in Seyfert2 nuclei : comparison with our Galactic center lines of sight
E. Dartois, O. Marco, G. M. Muñoz-Caro +3
We present ESO - Very Large Telescope and ESA - Infrared Space Observatory 3 to 4 m spectra of Seyfert 2 nuclei as compared to our galactic center lines of sight. The diffuse in…
Results from a VLT-ISAAC survey of ices and gas around young stellar objects
K. M. Pontoppidan, H. Fraser, F. L. Schoeier +3
General results from a 3-5 micron spectroscopic survey of nearby low-mass young stellar objects are presented. L and M-band spectra have been obtained of \~50 low mass embedded you…
Detection of abundant solid CO in the disk around CRBR 2422.8-3423
W. F. Thi, K. M. Pontoppidan, E. F. van Dishoeck +2
We present direct evidence for CO freeze-out in a circumstellar disk around the edge-on class I object CRBR 2422.8-3423, observed in the M band with VLT-ISAAC at a resolving power…
Bright CO ro-vibrational emission lines in the class I source GSS 30 IRS1: Probing the inner disk of a young embedded star
K. M. Pontoppidan, F. L. Schoeier, E. F. van Dishoeck +1
We present a 4.5-4.85 micron R=5000 spectrum of the low mass class I young stellar object GSS 30 IRS1 (L=25L_sun) in the rho Ophiuchus core, observed with the infrared spectrometer…
