Eder Martioli (CFHT) Title: Measuring Masses of Exoplanet Candidates Abstract: Most of exoplanets found to date has been detected by indirect methods. For instance the radial velocity method, responsible for the majority of detections, does not provide the most fundamental parameter for these objects, the mass, the reason why they are called "candidates". Here I will present some methods to obtain the true mass of exoplanet candidates, either used for following-up or detecting new objects. These include gravitational microlensing, transits, astrometry, and interferometry. I will also show study cases for which we have been able to apply some these techniques. Finally, I will discuss the impact of measuring exoplanetary masses and the main challenges for future research.
