Observational properties of brown dwarfs

Osservatorio Astrofisico di Torino

Brown dwarfs are objects with sub-stellar masses that are unable to sustain hydrogen burning; cooling down through out their lifetimes.
The physical parameterization of brown dwarfs is reliant on the use of interior and atmospheric models. The study of brown dwarf binaries can provide crucial model independent measurements, especially in the case of masses.
This talk will present some key results like the determination of the dynamical masses of the brown dwarf binary, ε Indi Ba, Bb (T1 and T6).
And it will integrate the study of benchmarks with the study of statistically meaningful populations, namely the mass function of brown dwarfs in clusters and in the field.
