Abstract

We report the detection of a broad absorption band at 2165 cm-1 (4.619 μm) in the spectrum of L1551 IRS 5. New laboratory results over the 2200-2100 cm-1 wavenumber interval (4.55-4.76 μm), performed with realistic interstellar ice analogs, suggest that this feature is due to a CN-containing compound. We will refer to this compound as XCN. We also confirm the presence of frozen CO (both in nonpolar and polar matrices) through absorption bands at 2140 cm-1 (4.67 μm) and 2135 cm-1 (4.68 μm). The relative abundance of solid-state CO to frozen H2O is ∼0.13 while the abundance of XCN seems comparable to that of frozen CO.
