Grand tack vs nice model
WebJan 7, 2016 · The Grand Tack model was resoundingly successful in explaining the characteristics of the present-day solar system. However, it drew a strong reaction from many astronomers for all the fine-tuned features it invoked. WebOct 16, 2014 · Two new models piece together a story of the evolution of the solar system. They are the Grand Tack and Nice models. The Grand Tack model addresses the formation of the inner solar system (Walsh et al. 2011; see also Morbidelli et al. 2012; Raymond et al. 2013; O'Brien et al. 2014).It invokes an inward-then-outward migration of …
