20th Microlensing Workshop:

Accurate mass measurements via microlensing

will take place at the Institut d'Astrophysique de Paris
in Paris, France 13-15 January  2016.

Registration is opened !

Scientific Rationale

The discovery of extrasolar planets is arguably the most exciting development in astrophysics over the past 20 years, rivaled only by the detection of dark energy. Two projects unite the communities of exoplanet scientists and cosmologists: the ESA M class mission EUCLID and the large NASA mission WFIRST.

The gravitational microlensing technique explores a unique niche: cold planets down to small masses orbiting any kind of stars (including stellar remnants), free-floating planets (unbound to a star), and exomoons orbiting planets. Over the last 10 years, the community evolved from individual competitive microlensing planet-hunting teams into a worldwide combined network of telescopes performing coordinated observations and sharing data including feedback from nearly real time modelling. Now, the microlensing community is taking advantage of the deployment around the world of wide field imagers and the use of large programs on board Spitzer and dedicated Kepler-2 campaign in 2016.

The 20th Microlensing Workshop will take place at the Institut d'Astrophysique de Paris on 13-15 Jan 2016. It will be a forum to discuss recent work, to exchange ideas and experiences in all areas of gravitational microlensing and its applications. There will be a special focus on mass measurement techniques using high angular resolution observations and ground-space parallaxes with Spitzer and Kepler-2.
