ALMA SURVEY OF LUPUS PROTOPLANETARY DISKS. I. DUST AND GAS MASSES

ABSTRACT We present the first high-resolution sub-millimeter survey of both dust and gas for a large population of protoplanetary disks. Characterizing fundamental properties of protoplanetary disks on a statistical level is critical to understanding how disks evolve into the diverse exoplanet population. We use the Atacama Large Millimeter/Submillimeter Array (ALMA) to survey 89 protoplanetary disks around stars with in the young (1–3 Myr), nearby (150–200 pc) Lupus complex. Our observations cover the 890 μ m continuum and the 13 CO and C 18 O 3–2 lines. We use the sub-millimeter continuum to constrain to a few Martian masses (0.2–0.4 M ⊕ ) and the CO isotopologue lines to constrain to roughly a Jupiter mass…
