Grand tack scenario
WebSep 9, 2016 · In this approach, Earth’s growth history comes from state-of-the-art N-body accretion simulations based on the “Grand Tack” scenario (9–12), which start with a protoplanetary disk consisting of 80 to 220 roughly Mars-sized embryos and several thousand smaller planetesimals distributed initially over heliocentric distances of 0.7 to 10 ... 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 ...

WebJun 26, 2015 · In the Grand Tack (GT) scenario for the young solar system, Jupiter formed beyond 3.5 AU from the Sun and migrated as close as 1.5 AU until it encountered an orbital resonance with Saturn. Both planets then supposedly migrated outward for several 10 5 yr, with Jupiter ending up at ≈ 5 AU. The initial conditions of the GT and the timing ...

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 ...
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.
