Recent Atacama Large Millimeter/submillimeter Array (ALMA) observations of protoplanetary disks in the millimeter continuum have shown a variety of radial gaps, cavities, and spiral features. These substructures may be signposts for ongoing planet fo

The first ALMA survey of protoplanetary discs at 3 mm: demographics of grain growth in the Lupus region

Autor: Tazzari, Marco, Testi, Leonardo, Natta, Antonella, Williams, Jonathan P., Ansdell, Megan, Carpenter, Jonathan M., Facchini, Stefano, Guidi, Greta, Hogherheijde, Michiel, Manara, Carlo F., Miotello, Anna, van der Marel, Nienke

We present the first ALMA survey of protoplanetary discs at 3 mm, targeting 36 young stellar objects in the Lupus star-forming region with deep observations (sensitivity 20-50 microJy/beam) at ~0.35" resolution (~50 au). Building on previous ALMA sur

We present $L^\prime$-band Keck/NIRC2 imaging and $H$-band Subaru/AO188+HiCIAO polarimetric observations of CQ Tau disk with a new spiral arm. Apart from the spiral feature our observations could not detect any companion candidates. We traced the spi

Lupus disks with faint CO isotopologues: low gas/dust or large carbon depletion?

An era has started in which gas and dust can be observed independently in protoplanetary disks, thanks to the recent surveys with ALMA. The first near-complete high-resolution disk survey in both dust and gas in a single star-forming region has been
