Scientific paper

The L723 low mass class 0 protostellar object has been observed with the IRS low resolution spectrometer onboard Spitzer Space Telescope. A huge CO2 ice column density of 6.3 ± 1 × 1018 cm-2 is detected toward this extremely red object. We constructed the spectral energy distribution (SED) of L723 by combining the Spitzer spectral data with Infrared Space Observatory (ISO) camera extracted fluxes, IRAS points, ISO long wavelength spectrometer (LWS) observations and millimeter ground based observations. A self consistent 1D model was developed to fit the SED. We show that, besides the high CO2 column density, the abundance ratio of CO2 ice to silicates grain cores is similar to other lines-of-sight.
