Cool Stars 14 - Submitted Abstract # 14 This version created on 05 October 2006 Planetary mass cloud cores in Ophiuchus Jane Greaves, University of St Andrews (For splinter session on proto-brown dwarfs) Cores of planetary mass have been identified in the cloud Ophiuchus D, using thermal dust images made with the SCUBA submillimetre camera. The counts suggest such low-mass cores are a simple extension of the clump mass function in the stellar-mass regime. Millimetre spectral lines were detected for a few cores, and one object was found to be gravitationally bound at only 8 Jupiter masses. The data support the idea that planetary mass objects can form like stars, from their own natal cloud cores. ----------------------------------
