Abstract:<br>
The last three decades have seen increasing number of
exoplanets being discovered in diverse environments,
displaying vastly different properties. With interesting
statistical trends that are emerging from such planet
demographics, the community is at the wake of a rigorous
revision of its current understanding of how planets form and
evolve. To form accurate theories, however, they need to be
based on a planet population that spans the complete range of
parameter space with respect to the properties of both the
planets and their host stars. A powerful tool that aids in
this goal is the technique of direct detection that targets
young, sub-stellar companions in wide orbits around their host
stars. This is the research topic covered by my PhD thesis,
which I will defend in the coming weeks. In this talk, I will
attempt to explain how the techniques of direct imaging and
spectroscopy help detect and characterize sub-stellar objects
that have either recently formed or are in the process of
formation, citing examples from the publications that are part
of my thesis, and discuss how such observations aid
in constraining formation models of planets and brown dwarfs.<br>
