Origin of the cataclysmic Late Heavy Bombardment period of the terrestrial planets
Nature, 2005 The petrology record on the Moon suggests that a cataclysmic spike in the cratering rate occurred ∼700 million years after the planets formed; this event is known as the Late Heavy Bombardment (LHB).

Multiverse Predictions for Habitability: Number of Potentially Habitable Planets
Universe, 2019 How good is our universe at making habitable planets? The answer to this depends on which factors are important for life: Does a planet need to be Earth mass? Does it need to be inside the temperate zone? are systems with hot Jupiters habitable? Here, we

Prospects for the characterization of habitable planets
Comptes Rendus. Physique, 2023 With thousands of exoplanets now identified, the characterization of habitable planets and the potential identification of inhabited ones is a major challenge for the coming decades.

Disc-planet, planet-planet, and star-planet interactions during planet formation
, 2003 In this article we present results from three on-going projects related to the formation of protoplanets in protostellar discs. We present the results of simulations that model the interaction between embedded protoplanets and disc models undergoing MHD turbulence.

Observing the Atmospheres of Known Temperate Earth-sized Planets with JWST [PDF]
, 2017 Nine transiting Earth-sized planets have recently been discovered around nearby late-M dwarfs, including the TRAPPIST-1 planets and two planets discovered by the MEarth survey, GJ 1132b and LHS 1140b. These planets are the smallest known planets that may

Atmospheric reconnaissance of the habitable-zone Earth-sized planets orbiting TRAPPIST-1 [PDF]
, 2018 Seven temperate Earth-sized exoplanets readily amenable for atmospheric studies transit the nearby ultracool dwarf star TRAPPIST-1 (refs 1,2). Their atmospheric regime is unknown and could range from extended primordial hydrogen-dominated to depleted ...

Radial Migration of Gap-opening Planets in Protoplanetary Disks. I. The Case of a Single Planet [PDF]
Astrophysical Journal, 2018 A large planet orbiting a star in a protoplanetary disk opens a density gap along its orbit due to the strong disk–planet interaction and migrates with the gap in the disk.
