About the symposium

This one-day symposium at Lund Observatory focuses on the ongoing search for planets around other stars. Today astronomers know of more than 3,500 such exoplanets and the catalogue will expand enormously in the future from ongoing ground-based and space-based surveys (e.g. Kepler and Gaia) and future space missions such as JWST, CHEOPS, TESS, E-ELT and PLATO. The hunt for habitable planets has begun!

The goal of this symposium is to highlight the state-of-the-art in radial velocity and transit searches for exoplanets as well as spectroscopic characterisation of exoplanet atmospheres.


The symposium consists of talks from four invited speakers:

  • Professor Stéphane Udry, Geneva Observatory, University of Geneva
  • Dr Sarah Ballard, Torres Fellow, Kavli Institute, Massachusetts Institute of Technology
  • Dr Laura Kreidberg, Harvard Society of Fellows Junior Fellow and ITC Fellow, Harvard-Smithsonian Center for Astrophysics, Harvard University
  • Dr Henriette Schwarz, Morrison Fellow, University of California, Santa Cruz
The symposium starts at 09:30 and ends at 16:00.

09:30-09:50: Welcome coffee

09:50-10:00: Introduction (Anders Johansen)

10:00-11:00: Sarah Ballard: "The Grand Planetary Ensemble"

11:00-12:00: Stéphane Udry: "Radial-velocity surveys of exoplanets: the age of maturity"

12:00-13:00: Lunch (sandwiches served in the foyer)

13:00-14:00: Laura Kreidberg: "The Present and Future of Exoplanet Atmosphere Characterization from Space"

14:00-15:00: Henriette Schwarz: "Ground-based high-resolution spectroscopy: A powerful tool for characterizing exoplanets and their atmospheres"

15:00-15:30: Coffee and cake

15:30-16:00: Panel discussion (discussion leader: Professor Sofia Feltzing)


All talks will be held in Lundmarksalen at Lund Observatory in the astronomy building. Lunch will be provided for all participants in the foyer of the astronomy building.

The symposium is kindly sponsored by the "Gunnar och Gunnel Källéns minnesfond". Gunnar Källén (1926-1968) was a professor in Theoretical Physics at Lund University, who made significant contributions to quantum field theory and elementary particle physics. After the passing of both Gunnar and his wife Gunnel, the "Gunnar och Gunnel Källéns minnesfond" was created in their honour.
