Effect of the Planetesimal Belt on the Dynamics of the Restricted Problem of 2 + 2 Bodies
Applied Sciences, 2022 In this paper, we study the existence and stability of collinear and noncollinear equilibrium points within the frame of the perturbed restricted problem of 2 + 2 bodies by a planetesimal belt.

The Astrophysical Journal, 2023 We model the early stages of planet formation in the solar system, including continual planetesimal formation, and planetesimal and pebble accretion onto planetary embryos in an evolving disk driven by a disk wind.

Planetesimal Initial Mass Functions Following Diffusion-regulated Gravitational Collapse
The Astrophysical Journal, 2023 The initial mass function (IMF) of planetesimals is of key importance for understanding the initial stages of planet formation, yet theoretical predictions so far have been insufficient in explaining the variety of IMFs found in simulations.

Ice Sublimation in Planetesimals Formed at the Outward Migrating Snowline
The Astrophysical Journal Letters, 2023 Isotopic studies of meteorites suggest that planetesimals were formed as two distinct populations: noncarbonaceous (NC) and carbonaceous (CC) reservoirs.

Planetesimal Formation by the Gravitational Instability of Dust Ring Structures
The Astrophysical Journal, 2023 We investigate the gravitational instability (GI) of dust ring structures and the formation of planetesimals by their gravitational collapse. The normalized dispersion relation of a self-gravitating ring structure includes two parameters that are related

Planetesimal formation starts at the snow line [PDF]
, 2017 Planetesimal formation stage represents a major gap in our understanding of the planet formation process. The late-stage planet accretion models typically make arbitrary assumptions about planetesimals and pebbles distribution while the dust evolution ...

Steady-state evolution of debris disks around A stars [PDF]
, 2007 In this paper a simple analytical model for the steady-state evolution of debris disks due to collisions is confronted with Spitzer observations of main sequence A stars.

Frontiers in Earth Science, 2018 Core formation has left a lasting geochemical signature on the Earth. In order to constrain the composition of the Earth we must fully understand the processes by which newly formed Earth, and the bodies which accreted to it, differentiated.

Planet formation in slightly inclined binary systems
EPJ Web of Conferences, 2011 One of the major problems of planet formation in close binary systems, such as α Centauri AB, is the formation of planetary embryos or cores by mutual accretion of km-sized planetesimals.

Planetesimal Accretion at Short Orbital Periods
The Astrophysical Journal, 2023 Formation models in which terrestrial bodies grow via the pairwise accretion of planetesimals have been reasonably successful at reproducing the general properties of the Solar System, including small-body populations. However, planetesimal accretion has
