This is in part thanks to the high angular resolution that (sub)mm observations can provide. Here we present the combined results of ALMA (0.9 mm) and VLA (7 mm) dust continuum observations toward the protoplanetary disk around the solar analogue GM Aur. Both images clearly resolve the $\\sim$35 au inner cavity. The ALMA observations also reveal a fainter disk that extends up to $\\sim250$ au. We model our observations using two approaches: an analytical fit to the observed depr","authors_text":"Alvaro Ribas, Carlos Carrasco-Gonzalez, Catherine C.
