A tale of planet formation: from dust to planets [PDF]

open access: yesResearch in Astronomy and Astrophysics, 2020
The characterization of exoplanets and their birth protoplanetary disks has enormously advanced in the last decade. Benefitting from that, our global understanding of the planet formation processes has been substantially improved.

Challenges in planet formation [PDF]

open access: yesJournal of Geophysical Research: Planets, 2016
Over the past two decades, large strides have been made in the field of planet formation. Yet fundamental questions remain. Here we review our state of understanding of five fundamental bottlenecks in planet formation.

A Brief Overview of Planet Formation [PDF]

open access: yes, 2018
The initial conditions, physics, and outcome of planet formation are now constrained by detailed observations of protoplanetary disks, laboratory experiments, and the discovery of thousands of extrasolar planetary systems.

Terrestrial planet formation. [PDF]

open access: yesProc Natl Acad Sci U S A, 2011
Advances in our understanding of terrestrial planet formation have come from a multidisciplinary approach. Studies of the ages and compositions of primitive meteorites with compositions similar to the Sun have helped to constrain the nature of the building blocks of planets.

The Perseus ALMA Chemistry Survey (PEACHES). II. Sulfur-bearing Species and Dust Polarization Revealing Shocked Regions in Protostars in the Perseus Molecular Cloud

open access: yesThe Astrophysical Journal, 2023
In protostellar cores, sulfur species are effective probes for the energetic environments, such as shocked regions. With the majority of sulfur depleted on dust grains, sulfur-bearing molecules could be liberated back to gas phase by shocks associated ...

A New Window into Planet Formation and Migration: Refractory-to-Volatile Elemental Ratios in Ultra-hot Jupiters [PDF]

open access: yes, 2020
A primary goal of exoplanet characterization is to use a planet’s current composition to understand how that planet formed. For example, the C/O ratio has long been recognized as carrying important information on the chemistry of volatile species ...

A Case of Simultaneous Star and Planet Formation [PDF]

open access: yesAstrophysical Journal, 2020
While it is widely accepted that planets are formed in protoplanetary disks, there is still much debate on when this process happens. In a few cases protoplanets have been directly imaged, but for the vast majority of systems, disk gaps and cavities—seen

Silicate Melting and Vaporization During Rocky Planet Formation [PDF]

open access: yesJournal of Geophysical Research: Planets, 2020
Collisions that induce melting and vaporization can have a substantial effect on the thermal and geochemical evolution of planets. However, the thermodynamics of major minerals are not well known at the extreme conditions attained during planet formation.

Planet formation and migration [PDF]

open access: yesReports on Progress in Physics, 2005
We review the observations of extrasolar planets, ongoing developments in theories of planet formation, orbital migration, and the evolution of multiplanet systems.

Interior and Evolution of the Giant Planets

open access: yesRemote Sensing, 2023
The giant planets were the first to form and hold the key to unveiling the solar system’s formation history in their interiors and atmospheres.
