  • Rare Event Sampling Improves Mercury Instability Statistics 
    Abbot, Dorian S.; Webber, Robert J.; Hadden, Sam; Seligman, Darryl; Weare, Jonathan (2021)
    Due to the chaotic nature of planetary dynamics, there is a non-zero probability that Mercury's orbit will become unstable in the future. Previous efforts have estimated the probability of this happening between 3 and ...
  • Simple Physics and Integrators Accurately Reproduce Mercury Instability Statistics 
    Abbot, Dorian S.; Hernandez, David M.; Hadden, Sam; Webber, Robert J.; Afentakis, Georgios P.; Weare, Jonathan (2023)
    The long-term stability of the solar system is an issue of significant scientific and philosophical interest. The mechanism leading to instability is Mercury's eccentricity being pumped up so high that Mercury either ...
  • Snowball Earth climate dynamics and Cryogenian geology-geobiology 
    Hoffman, Paul F.; Abbot, Dorian S.; Ashkenazy, Yosef; Benn, Douglas I.; Brocks, Jochen J.; Cohen, Phoebe A.; Cox, Grant M.; Creveling, Jessica R.; Donnadieu, Yannick; Erwin, Douglas H.; Fairchild, Ian J.; Ferreira, David; Goodman, Jason C.; Halverson, Galen P.; Jansen, Malte F.; Le Hir, Guillaume; Love, Gordon D.; Macdonald, Francis A.; Maloof, Adam C.; Partin, Camille A.; Ramstein, Gilles; Rose, Brian E. J.; Rose, Catherine V.; Sadler, Peter M.; Tziperman, Eli; Voigt, Aiko; Warren, Stephen G. (2017)
    Geological evidence indicates that grounded ice sheets reached sea level at all latitudes during two long-lived Cryogenian (58 and =5 My) glaciations. Combined uranium-lead and rhenium-osmium dating suggests that the older ...
