The search for gas in debris discs: ALMA detection of CO gas in HD 36546
Isabel Rebollido, Álvaro Ribas, Itziar de Gregorio-Monsalvo +9
Debris discs represent the last stages of planet formation and as such are expected to be depleted of primordial gas. Nonetheless, in the last few years the presence of cold gas ha…
Characterization of the dust content in the ring around Sz 91: indications for planetesimal formation?
Karina Maucó, Carlos Carrasco-González, Matthias R. Schreiber +6
One of the most important questions in the field of planet formation is how mm-cm sized dust particles overcome the radial drift and fragmentation barriers to form kilometer-sized…

M. Villenave, F. Menard, W. R. F. Dent +13
Context. Characterizing the evolution of protoplanetary disks is necessary to improve our understanding of planet formation. Constraints on both dust and gas are needed to determin…
Gaia Early Data Release 3: The Galactic anticentre

We produce a clean and well-characterised catalogue of objects within 100\,pc of the Sun from the \G\ Early Data Release 3. We characterise the catalogue through comparisons to the…
Gaia Early Data Release 3: Acceleration of the solar system from Gaia astrometry
Gaia Collaboration, S. A. Klioner, F. Mignard +414

Alice Zurlo, Lucas A. Cieza, Sebastián Pérez +9
We present Adaptive Optics (AO) near infrared (NIR) observations using VLT/NACO and Keck/NIRC2 of ODISEA targets. ODISEA is an ALMA survey of the entire population of circumstellar…
Exocomets: A spectroscopic survey
I. Rebollido, C. Eiroa, B. Montesinos +18
While exoplanets are now routinely detected, the detection of small bodies in extrasolar systems remains challenging. Since the discovery of sporadic events interpreted as exocomet…
The widest H survey of accreting protoplanets around nearby transition disks
A. Zurlo, G. Cugno, M. Montesinos +6
The mechanisms of planet formation are still under debate. We know little about how planets form, even if more than 4000 exoplanets have been detected to date. Recent investigation…
NaCo polarimetric observations of Sz 91 transitional disk: a remarkable case of dust filtering
Karina Maucó, Johan Olofsson, Hector Canovas +10
We present polarized light observations of the transitional disk around Sz 91 acquired with VLT/NaCo at (1.7m) and (2.2m) bands. We resolve the disk and detect pola…
Alma Survey Of Circumstellar Disks In The Young Stellar Cluster IC 348
D. Ruíz-Rodríguez, L. A. Cieza, J. P. Williams +7
We present a 1.3 mm continuum survey of the young (2-3 Myr) stellar cluster IC 348, which lies at a distance of 310 pc, and is dominated by low-mass stars (M 0.1-0…
Resolving faint structures in the debris disk around TWA7
J. Olofsson, R. G. van Holstein, A. Boccaletti +51
Debris disks are the intrinsic by-products of the star and planet formation processes. Most likely due to instrumental limitations and their natural faintness, little is known abou…
The co-existence of hot and cold gas in debris discs
I. Rebollido, C. Eiroa, B. Montesinos +19
Debris discs have often been described as gas-poor discs as the gas-to-dust ratio is expected to be considerably lower than in primordial,protoplanetary discs. However, recent obse…
ALMA observations of Elias 2-24: a protoplanetary disk with multiple gaps in the Ophiuchus Molecular Cloud
Lucas A. Cieza, Simon Casassus, Sebastian Perez +21
We present ALMA 1.3 mm continuum observations at 0.2" (25 au) resolution of Elias 2-24, one of the largest and brightest protoplanetary disks in the Ophiuchus Molecular Cloud, and…

We present Atacama Large Millimeter/sub-millimeter Array (ALMA) observations of the star-forming environment surrounding V1647 Ori, an outbursting FUor/EXor pre-MS star. Dust conti…
A 80 au cavity in the disk around HD 34282
G. van der Plas, F. Menard, H. Canovas +5
Context: Large cavities in disks are important testing grounds for the mechanisms proposed to drive disk evolution and dispersion, such as dynamical clearing by planets and photo-e…

BP Piscium: its flaring disk imaged with SPHERE/ZIMPOL
J. de Boer, J. H. Girard, H. Canovas +9
Whether BP Piscium (BP Psc) is either a pre-main sequence T Tauri star at d ~ 80 pc, or a post-main sequence G giant at d ~ 300 pc is still not clear. As a first-ascent giant, it i…
