Infrared Observations of Hot Gas and Cold Ice toward the Low Mass Protostar Elias 29
A. C. A. Boogert, A. G. G. M. Tielens, C. Ceccarelli +5
We have obtained the full 1-200 um spectrum of the low luminosity (36 Lsun) Class I protostar Elias 29 in the Rho Ophiuchi molecular cloud. It provides a unique opportunity to stud…
Mid-infrared ISO spectroscopy of NGC 4945
H. W. W. Spoon, J. Koornneef, A. F. M. Moorwood +2
We have observed the central region of the nearby starburst galaxy NGC4945 with the mid-infrared spectrometers SWS and PHT-S aboard ISO. We do not find any evidence for the existen…
HST/NICMOS Imaging of the Planetary Nebula Hubble 12
Joseph L. Hora, William B. Latter, Aditya Dayal +4
Images of Hubble 12 were obtained with the HST/NICMOS instrument in the F110W, F164N, and F166N filters of NIC1, and the F160W, F187N, F190N, F212N, F215N filters of NIC2. The imag…
ISO Spectroscopy of Young Intermediate-Mass Stars in the BD+40 4124 Group
M. E. van den Ancker, P. R. Wesselius, A. G. G. M. Tielens
We present the results of ISO SWS and LWS grating scans towards the three brightest members of the BD+40 4124 group in the infrared: BD+40 4124 (B2Ve), LkHalpha 224 (A7e) and the e…
