Constraining disk evolution prescriptions of planet population synthesis models with observed disk masses and accretion rates [PDF]

, 2019
While planets are commonly discovered around main-sequence stars, the processes leading to their formation are still far from being understood. Current planet population synthesis models, which aim to describe the planet formation process from the ...

High-eccentricity Migration with Disk-induced Spin–Orbit Misalignment: A Preference for Perpendicular Hot Jupiters

The Astrophysical Journal Letters, 2023
High-eccentricity migration is a likely formation mechanism for many observed hot Jupiters, particularly those with a large misalignment between the stellar spin axis and orbital angular momentum axis of the planet.

The Ophiuchus DIsk Survey Employing ALMA (ODISEA): A Unified Evolutionary Sequence of Planet-driven Substructures Explaining the Diversity of Disk Morphologies

The Astrophysical Journal Letters
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 appear smooth, most exhibit diverse substructures such as gaps, rings, or

Origin of the Asymmetric Gas Distribution near the Co-orbital Lagrange Points of an Embedded Planet

The Astrophysical Journal
Hydrodynamic simulations of planet–disk interactions often show material accumulation near the co-orbital Lagrange points L _4 and L _5 —features that may correspond to observed crescents in protoplanetary disks. Intriguingly, these simulations also show

Planet-Disk Interactions and Early Evolution of Planetary Systems [PDF]

, 2014
The great diversity of extrasolar planetary systems has challenged our understanding of how planets form, and how their orbits evolve as they form. Among the various processes that may account for this diversity, the gravitational interaction between planets and their parent protoplanetary disc plays a prominent role in shaping young planetary systems.

Puffed-up Edges of Planet-opened Gaps in Protoplanetary Disks. II. The Role of the Planet’s Orbital Eccentricity

The Astrophysical Journal
Eccentric planets constitute a large population of the known exoplanets and may drive significant substructures in protoplanetary disks through planet–disk interactions if their eccentricities are excited early in the planet formation process.

Environmental interactions in class II systems and their impact on the disk-planet architecture

Astronomy & Astrophysics
Context. Protoplanetary disks evolve in clustered environments where interactions with nearby stars and interstellar gas are common. Such environmental processes, including stellar flybys and gas infall, can significantly perturb disk structures over a ...
