Planetary formation and early phases
Comptes Rendus. Physique, 2023 Planets form in proto-planetary disks. In this review, we describe the structure and properties of such disks, and the various phenomenons that lead to the final product: a planetary system. First, micrometre dust settles and coagulates.

Challenges, 2023 We are in the midst of an unprecedented public and planetary health crisis. A major driver of this crisis is the current nutrition transition—a product of globalization and powerful multinational food corporations promoting industrial agriculture and the

Dissipative Capture of Planets into First-order Mean-motion Resonances
The Astrophysical Journal Letters, 2023 The emergence of orbital resonances among planets is a natural consequence of the early dynamical evolution of planetary systems. While it is well established that convergent migration is necessary for mean-motion commensurabilities to emerge, recent ...

Final Masses of Giant Planets. III. Effect of Photoevaporation and a New Planetary Migration Model [PDF]
Astrophysical Journal, 2019 We herein develop a new simple model for giant planet formation that predicts the final mass of a giant planet born in a given disk by adding the disk mass loss due to photoevaporation and a new type II migration formula to our previous model.

Evidence for Hidden Nearby Companions to Hot Jupiters
The Astronomical Journal, 2023 The first discovered extrasolar worlds—giant, “hot Jupiter” planets on short-period orbits—came as a surprise to solar system–centric models of planet formation, prompting the development of new theories for planetary system evolution.

Consequences of planetary migration on the minor bodies of the early solar system [PDF]
Astronomy & Astrophysics, 2019 Pebble accretion is an efficient mechanism that is able to build up the core of the giant planets within the lifetime of the protoplanetary disc gas-phase. The core grows via this process until the protoplanet reaches its pebble isolation mass and starts

Unconditional hospitality: art and commons under planetary migration
Journal of Aesthetics & Culture, 2022 In both European and non-European cities, public spaces are formed by racist and segregative politics that influence everyday life. Planetary migration flows and recently implemented border politics tend to leave the most vulnerable in precarious ...

Brownian Motion in Planetary Migration [PDF]
The Astrophysical Journal, 2006 A residual planetesimal disk of mass 10-100 Earth masses remained in the outer solar system following the birth of the giant planets, as implied by the existence of the Oort cloud, coagulation requirements for Pluto, and inefficiencies in planet formation. Upon gravitationally scattering planetesimal debris, planets migrate.

TOI-1136 is a Young, Coplanar, Aligned Planetary System in a Pristine Resonant Chain
The Astronomical Journal, 2023 Convergent disk migration has long been suspected to be responsible for forming planetary systems with a chain of mean-motion resonances (MMRs). Dynamical evolution over time could disrupt the delicate resonant configuration. We present TOI-1136, a 700 ±
