cds-question@unistra.frradio-continuum-emissionyoung-stellar-objectsmolecular-cloudsastronomical-object-identificationsurveysWe present a multi-epoch radio study of the Taurus-Auriga star-forming complex made with the Karl G. Jansky Very Large Array at frequencies of 4.5GHz and 7.5GHz. We detect a total of 610 sources, 59 of which are related to young stellar objects (YSOs) and 18 to field stars. The properties of 56% of the young stars are compatible with non-thermal radio emission. We also show that the radio emission of more evolved YSOs tends to be more non-thermal in origin and, in general, that their radio properties are compatible with those found in other star-forming regions. By comparing our results with previously reported X-ray observations, we notice that YSOs in Taurus-Auriga follow a Gudel-Benz relation with {kappa}=0.03, as we previously suggested for other regions of star formation. In general, YSOs in Taurus-Auriga and in all the previous studied regions seem to follow this relation with a dispersion of ~1dex. Finally, we propose that most of the remaining sources are related with extragalactic objects but provide a list of 46 unidentified radio sources whose radio properties are compatible with a YSO nature.2015ApJ...801...91Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/801/91CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/328 : AllWISE Data Release (Cutri+ 2013)II/306 : The SDSS Photometric Catalog, Release 8 (Adelman-McCarthy+, 2011)VII/244 : Atlas and Catalog of Dark Clouds (Dobashi+, 2005)IX/10 : ROSAT All-Sky Bright Source Catalogue (1RXS) (Voges+ 1999)VIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)J/ApJS/216/26 : T Tauri in Taurus-Auriga with GALEX (Gomez de Castro+, 2015)J/ApJ/745/119 : Close companions to young stars.
