we propose iso follow-up observations towards the unique low-mass (m <0.1 m_sol) protostars detected in the nearby globular filament gf9. globular filaments have long been thought to represent major sites of low-mass star formation, but only now with our unbiased search for prestellar condensation have a number of candidate protostars been identified. our high-resolution single-dish & interferometric investi- gation strongly suggest low-mass accretion cores being presently built up in several of these dense globules, whose ir luminosity seems to derive from accretion onto the central object. red-shifted local self- absorption, observed towards several of the gravitationally unstable cores, is quantitatively consistent with the .inside-out. collapse scenario for the formation of low-mass stars developed by shu et al. we propose (spectro)photometric observations with isocam and isophot towards the protostellar cores detected in gf-9. the isophot data will complement our 1.3mm dust continuum maps, thus allowing to spatially deconvolve the radial density and temperature structure of the globule, while with isocam the very nature of the embedded central accreting object (the protostellar core) will be elucidated.

Mission Description
The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
