Effect of pebble flux-regulated planetesimal formation on giant planet formation [PDF]
Astronomy & Astrophysics, 2020 Context. The formation of gas giant planets by the accretion of 100 km diameter planetesimals is often thought to be inefficient. A diameter of this size is typical for planetesimals and results from self-gravity.

The distribution of volatile elements during rocky planet formation
Frontiers in Earth Science, 2023 Core segregation and atmosphere formation are two of the major processes that redistribute the volatile elements—hydrogen (H), carbon (C), nitrogen (N), and sulfur (S)—in and around rocky planets during their formation.

The Role of Early Giant-planet Instability in Terrestrial Planet Formation [PDF]
, 2020 The terrestrial planets are believed to have formed by violent collisions of tens of lunar- to Mars-size protoplanets at time t < 200 Myr after the protoplanetary gas disk dispersal (t 0).

Planet formation by pebble accretion in ringed disks [PDF]
Astronomy & Astrophysics, 2020 Context. Pebble accretion is expected to be the dominant process for the formation of massive solid planets, such as the cores of giant planets and super-Earths.

An Analytical Theory for the Growth from Planetesimals to Planets by Polydisperse Pebble Accretion
The Astrophysical Journal, 2023 Pebble accretion is recognized as a significant accelerator of planet formation. Yet only formulae for single-sized (monodisperse) distribution have been derived in the literature.

Setting the Stage: Planet Formation and Volatile Delivery [PDF]
, 2020 The diversity in mass and composition of planetary atmospheres stems from the different building blocks present in protoplanetary discs and from the different physical and chemical processes that these experience during the planetary assembly and ...

AGU Advances, 2021 Magnetic fields in the early solar system may have driven the inward accretion of the protoplanetary disk (PPD) and generated instabilities that led to the formation of planets and ring and gap structures.

Understanding the Impacts of Stellar Companions on Planet Formation and Evolution: A Survey of Stellar and Planetary Companions within 25 pc [PDF]
, 2020 We explore the impact of outer stellar companions on the occurrence rate of giant planets detected with radial velocities. We searched for stellar and planetary companions to a volume-limited sample of solar-type stars within 25 pc. Using adaptive optics
