제목: Observation of protoplanetary-disks with NOEMA and ALMA     

초록: 

  ALMA and NOEMA are 2 big mm-interferometers covering the full sky. They are ideal tools for the study of protoplanetary disks, the birth place of planets, both in continuum (dust) and molecular lines (gas). The increased spatial resolution and sensitivity of these telescopes has revolutionized our view of the protoplanetary disks, showing in peculiar that planetary formationmost likely occurs earlier than previously thought.
In this talk I will present several results obtained in the latest years with ALMA and/or NOEMA, in particular the case of GG Tau, a multiple system, the cases of edge-on disks, and molecular survey allowed by the new capabilities of the NOEMA interferometer.
