The low mass IMF and early evolution of young stellar clusters in the Gaia era
Titolo: The low mass IMF and early evolution of young stellar clusters in the Gaia era
Relatore: Estelle Moraux, IPAG, Grenoble
Abstract: It is now well established that most stars form in groups or clusters with N=10-105, but that about 90% of them are going to dissolve within a few Myrs after gas removal. To understand the general rules that govern how the majority of stars form, as well as the properties of stars that populate the galactic field, it is therefore crucial to study the formation and early evolution of stellar clusters.
In this talk I will focus on the low mass IMF of young open clusters and star forming regions. I will present recent results that seem to suggest that the system IMF is universal, at least down to 30 Jupiter masses. I will then show that the early dynamical evolution may however affect the shape of the mass function, even at very young ages. A way to quantify this effect is to look at the dynamical state of the cluster by investigating its spatial and kinematic distributions. I will discuss how Gaia data will help us to solve this issue.
