Planetesimals Around White Dwarfs [PDF]
, 2014 Evidence is convincing that a big fraction of extrasolar planetesimals can survive the red giant stage of a star and persist into the white dwarf phase. We argue that eventually, some of them do get perturbed into the tidal radius of the white dwarf and ...

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

Kozai effect on planetesimal accretion in highly inclined binaries
EPJ Web of Conferences, 2011 Planet formation in highly inclined binaries is a complex issue. The Kozai mechanism plays an important role in this situation, since it will lead to high eccentricity and high relative impact velocity of planetesimals, thus hinder the planetesimal ...

Distribution of Captured Planetesimals in Circumplanetary Gas Disks and Implications for Accretion of Regular Satellites [PDF]
, 2017 Regular satellites of giant planets are formed by accretion of solid bodies in circumplanetary disks. Planetesimals that are moving on heliocentric orbits and are sufficiently large to be decoupled from the flow of the protoplanetary gas disk can be ...

Numerical simulations for terrestrial planets formation
EPJ Web of Conferences, 2011 We investigate the formation of terrestrial planets in the late stage of planetary formation using two-planet model. At that time, the protostar has formed for about 3 Myr and the gas disk has dissipated.

Erosion of planetesimals by gas flow
, 2020 The first stages of planet formation take place in protoplanetary disks that are largely made up of gas. Understanding how the gas affects planetesimals in the protoplanetary disk is therefore essential.

Pebbles versus planetesimals The outcomes of population synthesis models [PDF]
, 2020 In the core accretion scenario, a massive core forms first and then accretes an envelope. When discussing how this core forms some divergences appear.

Thermal history, collisional history, and structure of the CK‐chondrite parent body
Meteoritics &Planetary Science, EarlyView.Abstract Major chondrite groups (H, L, LL, R, EH, EL, CK) with some members of petrologic type 5 and 6 also have some members of types 3 and 4; they do not have members of type 1 or 2. Their parent bodies had onion‐shell structures and were internally heated by the decay of 26Al.

Formation of the terrestrial planets from planetesimals [PDF]
, 1991 Formation of the terrestrial planets from planetesimals is discussed. The following subject areas are covered: (1) formation of the original planetesimals; (2) growth of planetesimals into planetary embryos; and (3) growth of runaway planetary embryos ...
