Grand tack scenario
WebApr 12, 2016 · The Grand Tack model of terrestrial planet formation has emerged in recent years as the premier scenario used to account for several observed features of the inner solar system. It relies on the early migration of the giant planets to gravitationally sculpt and mix the planetesimal disk down to ∼1 au, after which the terrestrial planets ...

WebApart from Mars’ low mass compared to Earth, the Grand Tack scenario can further account for the semi major axis distribution of the terrestrial planets and the stirred demography of the asteroid belt (DeMeo and Carry 2014; Brasser et al. 2024). The dynamical consequences of the Grand Tack model on the terrestrial planet region are … WebFeb 1, 2016 · Two major problems arise from Kaib and Chambers’ proposal. The first is that, apart from the Grand Tack model, no other viable scenario (let alone detailed model) exists to explain the LHB. For example, the suggestion made more than a decade ago that a rogue star passed close enough to the Sun to disrupt its primordial comet and asteroid ...

WebApr 1, 2024 · These simulations can be grouped into four potentially viable scenarios of Solar System formation (Classical, Annulus, Grand Tack, and Early Instability) for which we compile a total of 433 N-body simulations. We relate the outputs of these simulations to the chemistry of Earth's core and mantle using a melt-scaling law combined with a multi ... In planetary astronomy, the grand tack hypothesis proposes that Jupiter formed at a distance of 3.5 AU from the Sun, then migrated inward to 1.5 AU, before reversing course due to capturing Saturn in an orbital resonance, eventually halting near its current orbit at 5.2 AU. The reversal of Jupiter's … See more In the grand tack hypothesis Jupiter underwent a two-phase migration after its formation, migrating inward to 1.5 AU before reversing course and migrating outward. Jupiter's formation took place near the See more The hypothesis can be applied to multiple phenomena in the Solar System.

A small Mars may have been a low probability event as it occurs in a small, but non-zero, fraction of simulations that begin with planetesimals distributed across the entire inner Solar System. … See more Most of the accretion of Mars must have taken place outside the narrow annulus of material formed by the grand tack if Mars has a different … See more • Formation and evolution of the Solar System • Jumping-Jupiter scenario • Late Heavy Bombardment See more
WebJul 11, 2024 · They ran N-body simulations, altering variables such as the number of planetesimals, along the "Grand Tack" scenario, in which a baby Jupiter moves first closer to the Sun, and then back again to its current position. Under this scenario, the motion of Jupiter in the early Solar System had an extremely perturbing effect on the smaller rocks ...
