Spectroscopic Characterization of Interstellar Object 3I/ATLAS: Water Ice in the Coma

Bin Yang, Karen J. Meech, Michael Connelley +2

We present optical and near-infrared spectroscopy of the interstellar object 3I/ATLAS, obtained with Gemini-S/GMOS and NASA IRTF/SpeX on 2025 July 5 and July 14. The optical spectr…

On the nature of the enigmatic object IRAS 19312+1950: A rare phase of massive star formation?

M. A. Cordiner, A. C. A. Boogert, S. B. Charnley +7

IRAS 19312+1950 is a peculiar object that has eluded firm characterization since its discovery, with combined maser properties similar to an evolved star and a young stellar object…

Fire and Ice: IRS Mid-IR Spectroscopy of IRAS F00183--7111

H. W. W. Spoon, L. Armus, J. Cami +8

We report the detection of strong absorption and weak emission features in the 4--27 micron Spitzer-IRS spectrum of the distant ultraluminous infrared galaxy (ULIRG) IRAS F00183--7…

Mid-infrared spectral evidence for a luminous dust enshrouded source in Arp220

H. W. W. Spoon, A. F. M. Moorwood, D. Lutz +3

We have re-analyzed the 6-12 micron ISO spectrum of the ultra-luminous infrared galaxy Arp220 with the conclusion that it is not consistent with that of a scaled up version of a ty…

Ices in Star-Forming Regions: First Results from VLT-ISAAC

E. F. van Dishoeck, E. Dartois, W. F. Thi +8

The first results from a VLT-ISAAC program on L- and M-band infrared spectroscopy of deeply-embedded young stellar objects are presented. The advent of 8-m class telescopes allows…

The obscured mid-infrared continuum of NGC 4418: a dust- and ice-enshrouded AGN

H. W. W. Spoon, J. V. Keane, A. G. G. M. Tielens +2

We report the detection of absorption features in the 6-8 micron region superimposed on a featureless mid-infrared continuum in NGC 4418. For several of these features this is the…
