A faint companion around CrA-9: protoplanet or obscured binary?
V. Christiaens, M. -G. Ubeira-Gabellini, H. Cánovas +16
Understanding how giant planets form requires observational input from directly imaged protoplanets. We used VLT/NACO and VLT/SPHERE to search for companions in the transition disc…
Gaia Early Data Release 3: Structure and properties of the Magellanic Clouds
Gaia Collaboration, X. Luri, L. Chemin +417
We compare the Gaia DR2 and Gaia EDR3 performances in the study of the Magellanic Clouds and show the clear improvements in precision and accuracy in the new release. We also show…
The Ophiuchus DIsc Survey Employing ALMA (ODISEA)-III: the evolution of substructures in massive discs at 3-5 au resolution
Lucas A. Cieza, Camilo González-Ruilova, Antonio S. Hales +15
We present 1.3 mm continuum ALMA long-baseline observations at 3-5 au resolution of 10 of the brightest discs from the Ophiuchus DIsc Survey Employing ALMA (ODISEA) project. We ide…
A Tale of Two Transition Disks: ALMA long-baseline observations of ISO-Oph 2 reveal two closely packed non-axisymmetric rings and a 2 au cavity
Camilo González-Ruilova, Lucas A. Cieza, Antonio S. Hales +12
ISO-Oph 2 is a wide-separation (240 au) binary system where the primary star harbors a massive (M 40 M) ring-like disk with a dust cavity 50 au in r…
Gaia DR2 white dwarfs in the Hercules stream
Santiago Torres, Carles Cantero, María E. Camisassa +5
We analyzed the velocity space of the thin and thick-disk Gaia white dwarf population within 100 pc looking for signatures of the Hercules stellar stream. We aimed to identify thos…
A census of Oph candidate members from Gaia DR2
H. Cánovas, C. Cantero, L. Cieza +6
The Ophiuchus cloud complex is one of the best laboratories to study the earlier stages of the stellar and protoplanetary disc evolution. The wealth of accurate astrometric measure…
The Ophiuchus DIsc Survey Employing ALMA (ODISEA) - I : project description and continuum images at 28 au resolution
Lucas A. Cieza, Dary Ruíz-Rodríguez, Antonio Hales +20
We introduce the Ophiuchus DIsc Survey Employing ALMA (ODISEA), a project aiming to study the entire population of Spitzer-selected protoplanetary discs in the Ophiuchus Molecular…
Homogeneous Analysis of the Dust Morphology of Transition Disks Observed with ALMA: Investigating dust trapping and the origin of the cavities
P. Pinilla, M. Tazzari, I. Pascucci +11
We analyze the dust morphology of 29 transition disks (TDs) observed with ALMA at (sub-) millimeter-emission. We perform the analysis in the visibility plane to characterize the to…
The Multiplicity of M-Dwarfs in Young Moving Groups
Yutong Shan, Jennifer C. Yee, Brendan P. Bowler +11
We image 104 newly identified low-mass (mostly M-dwarf) pre-main sequence members of nearby young moving groups with Magellan Adaptive Optics (MagAO) and identify 27 binaries with…
