TL;DR: In this paper, the Atacama Large Millimeter/Submillimeter Array (ALMA) was used to survey 89 protoplanetary disks around stars with M∗ > 0.1 M in the young (1-3 Myr), nearby (150-200 pc) Lupus complex.

TL;DR: The first high-resolution sub-mm survey of both dust and gas for a large population of protoplanetary disks is presented in this article, where the authors use ALMA to survey 89 disks around stars with a few Martian masses (0.2--0.4~$M_{\oplus}$).

TL;DR: Chemical imaging of the carbon monoxide snow line in the disk around TW Hya, an analog of the solar nebula, is presented using high spatial and spectral resolution Atacama Large Millimeter/Submillimeter Array observations of diazenylium (N2H+), a reactive ion present in large abundance only where CO is frozen out.

TL;DR: The Heterodyne Instrument for the Far-Infrared on board the Herschel Space Observatory has detected emission lines from both spin isomers of cold water vapor from the disk around the young star TW Hydrae, hinting at a water ice reservoir equivalent to several thousand Earth oceans in mass.

TL;DR: In this paper, the authors used detailed dust radiative transfer models to disentangle the continuum emission from the envelopes and disks, and from that estimated their masses, and argued in favor of a picture in which circumstellar disks are formed early during the protostellar evolution and rapidly process material accreted from the larger scale envelope onto the central star.
