Protoplanetary discs of young VLMOs discovered in the IPHAS survey
In a previous study, Virtual Observatory tools were used to cross-match the IPHAS catalogue with the 2MASS catalogue for searching young very low-mass objects. We defined photometric criteria to identify Halpha emission sources with near-infrared colors similar to known young very low-mass stars and brown dwarfs. Spectral types have been derived
