14th March 2022: Discovery of a large sample of free-floating planets

Speaker: Núria Miret-Roig. Time: 3 pm.

The first free-floating planets were discovered at the turn of the century, but the lack of large samples prevents us from better understanding their origin and properties. Are they born orphans of planetary systems, or are they expelled from their place of birth in their childhood? I will present the largest homogeneous sample of free-floating planets to date and discuss how it can be used to shed light on their origin. The lack of precise ages is one of the main difficulties in knowing the mass of these objects. I will present a methodology based on kinematics to determine the ages of young stellar associations.
