a multi-wavelength isophot study is proposed to measure the ir energy distributions of a sample of protostar candidates. during a recent ground-based survey at the iram 30m and at sest, we have discovered a number of so far unknown sources of strong mm emission, which are the coldest and densest dust condensations ever found. despite our subsequent submm photometry at the jcmt it was not possible to constrain the temperature sufficiently well. the proposed isophot measurements will be combined with our existing mm/submm photometry in order to determine temperature, luminosity, mass, and evolutionary status of these young objects. microscanning with isocam will be performed to reveal possible embedded stellar sources.

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.
