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 ...

The planetary system around HD 190622 (TOI-1054)

, 2023
Context. Giant planets are known to dominate the long-term stability of planetary systems due to their prevailing gravitational interactions, but they are also thought to play an important role in planet formation.

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 with envelope enrichment: new insights on planetary diversity [PDF]

, 2016
Aims. We compute for the first time self-consistent models of planet growth that include the effect of envelope enrichment. The change in envelope metallicity is assumed to be the result of planetesimal disruption or icy pebble sublimation. Methods.

Implications of Differentiated Late Accretion for the Volatile Inventory of the Bulk Silicate Earth

The Planetary Science Journal
Earth is believed to have acquired its highly siderophile element (HSE) inventory through the late accretion of ∼0.3%–0.5% of its mass in chondrite-like materials, following the main stage of its growth. Late accretion, particularly if it originated from
