TL;DR
This study uses ALMA to survey dust and gas in 89 protoplanetary disks in Lupus, revealing correlations with star mass, rapid disk evolution, and implications for planet formation within a few million years.
Contribution
First high-resolution sub-mm survey of dust and gas in a large sample of Lupus disks, providing statistical insights into disk properties and evolution.
Findings
Detected 62 disks in dust, 36 in $^{13}$CO, 11 in C$^{18}$O
Found positive correlation between disk mass and star mass
Indicated rapid disk evolution and early planet formation
Abstract
We present the first high-resolution sub-mm 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 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~m continuum and the CO and CO 3--2 lines. We use the sub-mm continuum to constrain to a few Martian masses (0.2--0.4~) and the CO isotopologue lines to constrain to roughly a Jupiter mass (assuming ISM-like abundance). Of 89 sources, we detect 62 in continuum, 36 in CO, and 11 in CO at significance. Stacking individually…
