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.
