This workflow retieves information from Hubble Space Telescope VO Services in the form of VOTables. The input of the workflow is an ASCII file with a list of source names. This file is converted to a VOTable, and coordinates added with an extra-column needed to query SIAP Image service. The final result are two different VOTables issued as the response of both VO Services, Images VOTable has been previously filtered.

Discovery of Brown Dwarfs mining the 2MASS... (1)

• Download

Brown dwarfs are objects occupying the gap between the least massive stars and the most massive planets. They are intrinsically faint objects so their detection is not straighforward and, in fact, was almost impossible until the advent of global surveys at deep optical and near-infrared bands like SDSS, 2MASS or DENIS among others. Here we propose to mine the SDSS and 2MASS databases to identify T-type brown dwarfs through an appropriate combination of colours in the optical and the infra-red...
