Protoplanetary disc population synthesis I. Linking mass-dependent viscosity, star formation history and environment to observations
Jose L. Gomez, Octavio M. Guilera, Marcelo M. Miller Bertolami +4
Context. Recent studies highlight the importance of stellar mass sampling when determining disc lifetimes through observed disc fractions. Low-mass stars host discs with average li…
Quantifying the Impact of the Dust Torque on the Migration of Low-mass Planets II: The Role of Pebble Accretion in Planet Growth within a Global Planet Formation Model
Octavio M. Guilera, Pablo Benitez-Llambay, Marcelo M. Miller Bertolami +1
Although dust constitutes only about 1% of the mass of a protoplanetary disk, recent studies demonstrate that it can exert a significant torque on low- and intermediate-mass planet…
The Ophiuchus DIsk Survey Employing ALMA (ODISEA): A Unified Evolutionary Sequence of Planet-Driven Substructures Explaining the Diversity of Disk Morphologies
Santiago Orcajo, Lucas A. Cieza, Octavio Guilera +21
Understanding the origin of substructures in protoplanetary disks and their connection to planet formation is currently one of the main challenges in astrophysics. While some disks…
Ionized envelopes around protoplanets and the role of radiative feedback in gas accretion
MatÃas Montesinos, Juan Garrido-Deutelmoser, Jorge Cuadra +5
Planetary growth within protoplanetary disks involves accreting material from their surroundings, yet the underlying mechanisms and physical conditions of the accreting gas remain…
From Streaming Instability to the Onset of Pebble Accretion I. Investigating the Growth Modes in Planetesimal Rings
Nicolas Kaufmann, Octavio M. Guilera, Yann Alibert +1
Context. The localized formation of planetesimals can be triggered with the help of streaming instability when the local pebble density is high. This can happen at various location…
The Ophiuchus DIsk Survey Employing ALMA (ODISEA): Complete Size Distributions for the 100 Brightest Disks Across Multiplicity and SED Classes
Anuroop Dasgupta, Lucas A. Cieza, Camilo I. Gonzalez Ruilova +16
The size of a protoplanetary disk is a fundamental property, yet most remain unresolved, even in nearby star-forming regions (d 140-200 pc). We present the complete continuu…
