Séminaire du Mercredi 23 Mai 2012

The Dynamics of Newborn Triple Systems : Orphaned Protostars, Brown Dwarf Binaries, and Freefloating Planets

Bo Reipurth (U. of Hawaii)
Mercredi 23 Mai - 11 h 00
Salle Manuel Forestini - IPAG

Attention, exceptionnellement ce séminaire a lieu un mercredi, le jeudi 24 étant réservé pour la journée de l’observatoire.

Newly born triple systems are inherently unstable, and undergo chaotic dynamic evolution until they find a stable configuration or they break apart. Detailed numerical simulations of three stellar embryos embedded in a cloud core map out the effects of dynamics and accretion. These two processes interact in complex ways, and I explore the main pathways that stellar embryos follow as they gain mass during the protostellar phase. The results lead to observational predictions, and I present various new observations for comparison with the numerical simulations.
