Andrew Prentice is an Australian mathematician. He is known for developing an alternative model of planetary formation. In contrast to the conventional model where planetary accretion occurs within a continuous disk, according to Prentice's "Modern Laplacian Theory" each planet accretes within a discrete circumsolar gas ring. Prentice's nested gas rings arise due to the effect of 'supersonic turbulent convection' in slowing the infall of interstellar dust and gas. Instead of collapsing directly to form a flat continuous disk, due to 'turbulent stress' the gas temporarily remains puffed up in a vast rotating spheroidal atmosphere around the protosolar core. This atmosphere spins faster as it slowly contracts. It rids itself of excess angular momentum by sequentially shedding gas rings from

  • Andrew Prentice is an Australian mathematician. He is known for developing an alternative model of planetary formation. In contrast to the conventional model where planetary accretion occurs within a continuous disk, according to Prentice's "Modern Laplacian Theory" each planet accretes within a discrete circumsolar gas ring. Prentice's nested gas rings arise due to the effect of 'supersonic turbulent convection' in slowing the infall of interstellar dust and gas. Instead of collapsing directly to form a flat continuous disk, due to 'turbulent stress' the gas temporarily remains puffed up in a vast rotating spheroidal atmosphere around the protosolar core. This atmosphere spins faster as it slowly contracts. It rids itself of excess angular momentum by sequentially shedding gas rings from its equator. The same process repeats itself on a much smaller scale for each of the giant planets to produce their regular satellite systems. Prentice has used his unorthodox model to make a range of surprisingly accurate predictions about the Solar System. He is currently Emeritus Professor in the School of Mathematical Sciences at Monash University. (en)
  • Andrew Prentice (...) è un matematico e astrofisico australiano. È conosciuto per la sua vasta gamma di eterodosse, ma accurate previsioni circa il sistema solare e per aver teorizzato la turbolenza supersonica. È Lettore (Reader) presso l'Università di Monash, in Australia, ed insegna astrofisica stellare e planetaria. Noto per il suo stile originale, i suoi aneddoti ed espressioni folkloristiche in ambito astrofisico, è oggetto di ammirazione da parte dei propri allievi nelle facoltà di matematica ed astrofisica. Ha compiuti stupefacenti predizioni e ricevuto nell'arco degli anni una grande ammirazione in ambito internazionale, con giustificato stupore da parte di molti suoi colleghi della NASA in seguito alla conferma delle sue ipotesi.
