Early Water Delivery to Terrestrial Planet Regions during the Stages of Jupiter’s Formation and Migration in the Grand Tack Model

The Planetary Science Journal, 2023
The formation and subsequent migration of gas giants could significantly affect the material mixing in the solar system. In this study, we use N -body simulations to investigate how much water is transported into the region of the terrestrial planet ...

Two Wide Planetary-Mass Companions to Solar-Type Stars in Upper Scorpius [PDF]

, 2010
At wide separations, planetary-mass and brown dwarf companions to solar type stars occupy a curious region of parameters space not obviously linked to binary star formation or solar-system scale planet formation. These companions provide insight into the

Planets in binary systems: is the present configuration indicative of the formation process? [PDF]

, 2007
The present dynamical configuration of planets in binary star systems may not reflect their formation process since the binary orbit may have changed in the past after the planet formation process was completed.

Early Planet Formation in Embedded Disks (eDisk). IV. The Ringed and Warped Structure of the Disk around the Class I Protostar L1489 IRS

The Astrophysical Journal, 2023
Constraining the physical and chemical structure of young embedded disks is crucial for understanding the earliest stages of planet formation. As part of the Early Planet Formation in Embedded Disks Atacama Large Millimeter/submillimeter Array Large ...

The role of the initial surface density profiles of the disc on giant planet formation: comparing with observations [PDF]

, 2003
In order to explain the main characteristics of the observed population of extrasolar planets and the giant planets in the Solar System, we need to get a clear understanding of which are the initial conditions that allowed their formation. To this end we

Catching a planet: A tidal capture origin for the exomoon candidate Kepler 1625b I [PDF]

, 2018
The (yet-to-be confirmed) discovery of a Neptune-sized moon around the ~3.2 Jupiter-mass planet in Kepler 1625 puts interesting constraints on the formation of the system.

A Large Double-ring Disk Around the Taurus M Dwarf J04124068+2438157

The Astrophysical Journal, 2023
Planet formation imprints signatures on the physical structures of disks. In this paper, we present high-resolution (∼50 mas, 8 au) Atacama Large Millimeter/submillimeter Array observations of 1.3 mm dust continuum and CO line emission toward the disk ...

Let’s Sweep: The Effect of Evolving J 2 on the Resonant Structure of a Three-planet System

The Astrophysical Journal, 2023
Short and ultrashort period planets are peculiar types of exoplanets with periods as short as a few days or less. Although it is challenging to detect them, already several have been observed, with many additional candidates.

Planet Formation Imager (PFI): Introduction and Technical Considerations [PDF]

, 2014
Complex non-linear and dynamic processes lie at the heart of the planet formation process. Through numerical simulation and basic observational constraints, the basics of planet formation are now coming into focus.
