Title: A detective’s tool-kit to demystify sub-stellar origins: Direct 
imaging and characterization
Event: https://indico.fysik.su.se/e/gayathri_viswanath

Abstract:
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.
