Possible substellar objects in the RHO Ophiuchi cloud

Research output: Contribution to journalArticlepeer-review

23 Scopus citations


Three sources have been discovered in the embedded population of the ρ Ophiuchi cloud that have dereddened MK ≥ 7. Comparison with theoretical models for evolution of low-mass stars shows that these sources are substantially less luminous than expected for objects evolving onto the main sequence and of the age of the embedded cluster. The sources are probably substellar in mass, i.e., they may be young brown dwarfs.
