Abstract
ISO spectroscopic observations are reported towards the well known infrared source L1551 IRS 5. The continuum spectral energy distribution has been modelled using a 2D radiative transfer model, and fitted for a central source luminosity of 50 L⊙, surrounding a dense torus extending to a distance of ~ 30,000 AU, which has a total (gas + dust) mass of 25 M⊙. The extinction towards the outflow is estimated to be Av = 11 and the mid-plane optical depth to L1551 IRS 5 to be 140. On the basis of this model, the extinction curve shows that emission at wavelengths shorter than ~ 2 μm is due to scattered light from close to L1551 IRS 5, while at wavelengths greater than 4 μm, is seen through the full extinguishing column towards the central source.
