IA/U.Porto Cookie Seminar - Detection of rings around exoplanets - 15 março 2017

In this talk, I present on-going work on technique for detecting rings around exoplanets. It explores using transit photometry and Radial velocity to investigate exoplanetary rings. More emphasis is placed on high precision Radial Velocity as the Rossiter McLauglin anomaly induced by the rings of a transiting planet together with the transit light curve provides a way to characterise the effect of rings. This work employs numerical methods to show the detectability of exoplanetary rings using state-of-the-art instruments by investigating residuals between the ring planet signals and best fit ringless planet model for different orientations of the ring.
