Planet formation in highly inclined binaries
F. Marzari, P. Thebault, H. Scholl
TL;DR
This paper investigates how highly inclined binary star systems influence planet formation, focusing on planetesimal collisions and accretion processes within the habitable zone and beyond.
Contribution
It provides the first detailed analysis of planetesimal impact velocities in highly inclined binary systems, highlighting the effects on planet formation.
Findings
Impact velocities vary significantly with inclination and distance from the star.
High inclination binaries may hinder planetesimal accretion in certain regions.
Results suggest specific conditions under which planet formation is feasible in such systems.
Abstract
We explore planet formation in binary systems around the central star where the protoplanetary disk plane is highly inclined with respect to the companion star orbit. This might be the most frequent scenario for binary separations larger than 40 AU, according to Hale (1994). We focus on planetesimal accretion and compute average impact velocities in the habitable region and up to 6 AU from the primary.
