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

Silicate Melting and Vaporization During Rocky Planet Formation [PDF]
Journal 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.

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).

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.

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 ...

The Astrophysical Journal, 2023 We construct a one-dimensional protoplanetary disk model to investigate long-term disk evolution from molecular cloud core collapse. To obtain details of disk evolution, instead of solving the traditional diffusion equation for disk surface density, we ...

Early planet formation as a trigger for further planet formation [PDF]
, 1999 Recent discoveries of extrasolar planets at small orbital radii, or with significant eccentricities, indicate that interactions between massive planets and the disks of gas and dust from which they formed are vital for determining the final shape of ...
