Discovery of Two Infrared Objects with Strong Ice Absorption in the Akari Slitless Spectroscopic Survey of the Galactic Plane

We discover two infrared objects that show deep absorption features of H2O, CO2, and CO ices in the AKARI/Infrared Camera (IRC) slit-less spectroscopic survey Galactic plane 2.5--13 micron. Both are located neither known star-forming regions nor dense clouds. For one objects, Object 1, we successfully extract a spectrum from 2.5 to 13 micron, which also shows several 5--13 including silicate at 10 other object, 2, only 3.1 5 micron is reliably extracted due presence nearby overlapping faint nebulosity. warm (>100 K) gas addition ice features, suggesting they embedded young stellar (YSOs). On hand, both have spectral energy distributions (SEDs) peak around decrease towards longer wavelengths. These characteristics SEDs cannot easily be accounted for by standard YSO models. They may explained as background stars behind discuss possible nature implications present discovery.
