The protoplanetary disc around HD 169142: circumstellar or circumbinary?
P. P. Poblete, N. Cuello, S. Pérez +12
Stellar binaries represent a substantial fraction of stellar systems, especially among young stellar objects. Accordingly, binaries play an important role in setting the architectu…
A Circumplanetary Disk Around PDS70c
Myriam Benisty, Jaehan Bae, Stefano Facchini +14
PDS70 is a unique system in which two protoplanets, PDS70b and c, have been discovered within the dust-depleted cavity of their disk, at 22 and 34au respectively, by direct i…
Limits on Millimeter Continuum Emission from Circumplanetary Material in the DSHARP Disks
Sean M. Andrews, William Elder, Shangjia Zhang +10
We present a detailed analysis for a subset of the high resolution (~35 mas, or 5 au) ALMA observations from the Disk Substructures at High Angular Resolution Project (DSHARP) to s…
Photoevaporative Dispersal of Protoplanetary Disks around Evolving Intermediate-mass Stars
Masanobu Kunitomo, Shigeru Ida, Taku Takeuchi +3
We aim to understand the effect of stellar evolution on the evolution of protoplanetary disks. We focus in particular on the disk evolution around intermediate-mass (IM) stars, whi…
Characterizing the dust content of disk substructures in TW Hya
Enrique Macias, Osmar Guerra-Alvarado, Carlos Carrasco-Gonzalez +4
We present Atacama Large Millimeter Array (ALMA) observations of TW Hya at 3.1 mm with milliarcsecond resolution. These new data were combined with archival high angular r…
