====================================================================== ==> In this proposal, more time is being requested for PMYERS:DMARDONE ====================================================================== Mid-infrared imaging of extended nebulosity around low mass protostars can only be done from space, due to the high sensitivity required. We propose to obtain high resolution 6-16 um ISOCAM images of young nearby low mass protostars. This will locate accurately the central sources in relation to the outflow cavities and near-infrared reflection nebulae, and allow detailed modeling of circumstellar dust heating during the accretion/outflow phases. It will also permit a measurement of the heating due to shocks in Herbig-Haro (HH) jets and knots which will constrain current models of HH emission. We sucessfully used ISO to image the IRAS 11590-6452 in August 1996 (figure 1) and detected two point sources associated with the IRAS object (marked as A and B) and extended emission associated with the outflow (from both H2 and PAHs) proving the feasibility of this proposal. The sources in the sample are still undetected below 25 um with IRAS and ground-based sensitivities, they drive bipolar outflows and are closer than 460pc from the Sun. Our complete source sample will let study the distribition of warm dust at the base of the outflow cavities in low mass YSOs in general. This is essential to understand the geometrical interaction between infall and outflows in these sources.
