DEMOS. II. What the full Lupus demographics truly tell us about protoplanetary disc evolution
Lorenzo A. Malanga, Giovanni P. Rosotti, Giuseppe Lodato +7
Assessing whether disc evolution is driven by viscosity or MHD winds is crucial to determine the conditions in which planets form. The rich statistical information encoded in nearb…
Demographics of planet-forming disks with the SKAO
Antonio Garufi, Sebastián Pérez, John D. Ilee +21
Understanding how solid material in planet-forming disks evolves from micron-sized dust to planetary cores is a central challenge in modern astrophysics. This study has advanced dr…
Substructures in Planet-Forming Disks with the SKAO
Yinhao Wu, Jessica Speedie, Sebastián Pérez +33
Disks of gas and dust orbiting young stars are the arenas and material reservoirs for planet formation. Over the past decade, multiwavelength observations, from infrared to radio,…
Compact CO emission and no evidence of radial drift. ALMA observations of the faintest planet-forming disks in Lupus
Giulia Ricciardi, Francesco Zagaria, Anna Miotello +13
A large fraction of planet-forming disks observed with ALMA show faint CO emission, often interpreted as strong CO depletion. However, faint emission may also arise from spatially…
Probing Dust in the MWC 480 Disk from Millimeter to Centimeter Wavelengths
Yangfan Shi, Feng Long, Enrique Macías +12
We present deep, high-resolution (100 mas) Karl G. Jansky Very Large Array (VLA) Ka-band (9.1 mm) observations of the disk around MWC 480, and infer dust properties through a…
A tension between dust and gas radii: the role of substructures and external photoevaporation in protoplanetary disks
Luca Delussu, Rossella Anania, Tilman Birnstiel +5
Protoplanetary disk substructures are thought to play a crucial role in disk evolution and planet formation. Population studies of disks large-sample size surveys show that substru…
The ExoGRAVITY survey: A K-band spectral library of giant exoplanet and brown dwarf companions
J. Kammerer, T. O. Winterhalder, S. Lacour +106
Direct observations of exoplanet and brown dwarf companions with near-infrared interferometry, first enabled by the dual-field mode of VLTI/GRAVITY, provide unique measurements of…
The ALMA Survey of Gas Evolution of PROtoplanetary Disks (AGE-PRO): VII. Testing accretion mechanisms from disk population synthesis
Benoît Tabone, Giovanni P. Rosotti, Leon Trapman +24
The architecture of planetary systems depends on the evolution of the disks in which they form. In this work, we develop a population synthesis approach to interpret the AGE-PRO me…
The likelihood of not detecting cavity-carving companions in transition discs -- A statistical approach
Enrico Ragusa, Giuseppe Lodato, Nicolás Cuello +3
Protoplanetary discs with cavities, also known as ``transition discs'', constitute ~10% of protoplanetary discs at sub-mm wavelengths. Among several explanations, one hypothesis su…
The survivorship bias of protoplanetary disc populations
Lorenzo Alessio Malanga, Giovanni Pietro Rosotti, Giuseppe Lodato +4
The evolution of protoplanetary discs has a substantial impact on theories of planet formation. To date, neither of the two main competing evolutionary models, namely the viscous-p…
Protoplanetary disk insights from the first ERIS/APP survey at 4 μm
F. Maio, V. Roccatagliata, D. Fedele +17
We present high-contrast imaging observations of seven protoplanetary disks at 4um using the ERIS on the VLT. This study focuses on detecting scattered light from micron-sized dust…
The evolution of the and correlations traces protoplanetary disc dispersal
Alice Somigliana, Leonardo Testi, Giovanni Rosotti +9
(Abridged) Observational surveys of entire star-forming regions have provided evidence of power-law correlations between the disc properties and the stellar mass, especially the di…
Planet-driven spirals in protoplanetary discs: limitations of the semi-analytical theory for observations
D. Fasano, A. J. Winter, M. Benisty +7
Detecting protoplanets during their formation stage is an important but elusive goal of modern astronomy. Kinematic detections via the spiral wakes in the gaseous disc are a promis…
Orbital dynamics in the GG Tau A system: investigating its enigmatic disc
Claudia Toci, Simone Ceppi, Nicolás Cuello +6
GG Tau is one of the most studied multiple young stellar systems: GG Tau A is a hierarchical triple surrounded by a massive disc and its companion, GG Tau B, is also a binary. Desp…
The time evolution of in protoplanetary discs as a way to disentangle between viscosity and MHD winds
Alice Somigliana, Leonardo Testi, Giovanni Rosotti +5
As the classic viscous paradigm for protoplanetary disk accretion is challenged by the observational evidence of low turbulence, the alternative scenario of MHD disk winds is being…
Radio multiwavelength analysis of the compact disk CX Tau: Presence of strong free-free variability or anomalous microwave emission
Pietro Curone, Leonardo Testi, Enrique Macias +8
Protoplanetary disks emit radiation across a broad range of wavelengths, requiring a multiwavelength approach to fully understand their physical mechanisms and how they form planet…

Francesco Zagaria, Stefano Facchini, Anna Miotello +3
The Atacama Large Millimeter/submillimeter Array (ALMA) revolutionised our understanding of protoplanetary discs. However, the available data have not given conclusive answers yet…
