Observational properties of brown dwarfs

Cátia Cardoso
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.

Institute of Astrophysics and Space Sciences

Institute of Astrophysics and Space Sciences (IA) is a new but long anticipated research infrastructure with a national dimension. It embodies a bold but feasible vision for the development of Astronomy, Astrophysics and Space Sciences in Portugal, taking full advantage and fully realizing the potential created by the national membership of the European Space Agency (ESA) and the European Southern Observatory (ESO). IA resulted from the merging the two most prominent research units in the field in Portugal: the Centre for Astrophysics of the University of Porto (CAUP) and the Center for Astronomy and Astrophysics of the University of Lisbon (CAAUL). It currently hosts more than two-thirds of all active researchers working in Space Sciences in Portugal, and is responsible for an even greater fraction of the national productivity in international ISI journals in the area of Space Sciences. This is the scientific area with the highest relative impact factor (1.65 times above the international average) and the field with the highest average number of citations per article for Portugal.
