Description
During the last two and a half years we have explored how the Javalambre surveys (primarily J-VAR, the time-domain extension of J-PLUS) together with J-PLUS itself, can be used for Solar System science. Thanks to their wide coverage and multi-filter strategy we have recovered data for more than 17,000 small bodies, most of them located in the Main Belt. From J-VAR DR1 alone we compiled a catalog with about 6,500 unique objects, for which we could obtain photometry in up to seven filters and a first, broad taxonomic classification into three groups: carbonaceous, silicaceous and basaltic.
We combined these data with J-PLUS measurements to build a consistent photometric catalog, and derived some first statistics on the compositional distribution across the main belt, which nicely follows the expected trend from rocky to primitive types with increasing distance. We also tested lightcurve reconstruction using the high-frequency fields, and we started to apply the same dataset to the study of asteroid families and their halos, combining the photometric and dynamical information to investigate compositional coherence.
Altogether, this work sets up the OAJ surveys as a very useful resource for minor body science, and opens the door to more detailed analyses of asteroid populations.
