In its wake, the pandemic has dramatically transformed the way that academia conducts its conferences, workshops and summer schools. Most academic events now offer hybrid formats, allowing for the possibility of remote participation. Exoplanets by the Lake is intended to be a signature summer school series that aims to reinstate an interactive, in-person summer school format among participants that is not easily achievable online. In 2023, our focus is on the use of high-resolution spectroscopy and ground-based telescopes to probe the physical and chemical properties of the atmospheres of exoplanets. This line of research is highly synergistic with space-based telescopes like the JWST, while still providing unique insights into the dynamics of atmospheres and their molecular constituents. High-resolution spectroscopy of exoplanetary atmospheres is one of the key science cases of the Extremely Large Telescope, which will come online in the next decade.

The distinctive features of the summer school include:

  • Emphasis on in-person interaction at an attractive, self-contained venue with at most 50 participants. The number of participants is kept small in order to encourage unrestricted, interactive discussions among exoplanet scientists of all sub-disciplines and seniority.
  • The event will be held for 5 days (4 nights). The first 3 days involve pedagogical lectures during the day and evening guest lectures. There is an optional half-day excursion, via ship on the lake. The last 1.5 days feature a mini-conference format, where a small number of invited experts share their views and interact with the participants. Participants have the chance to contribute short talks, if desired.

The intended audience of this summer school ranges from Master students to junior postdocs. Both specialists in high-resolution spectroscopy of exoplanetary atmospheres and individuals who are curious about the topic are welcome to attend. Senior scientists who are intending to switch research directions and/or attending as active listeners are also welcome.

Lecturer profiles

Matteo Brogi

Matteo Brogi is an associate professor at the University of Turin in Italy.  He pioneered the use of high-resolution spectroscopy to measure the orbital inclinations and masses of non-transiting exoplanets.  He also co-developed cutting-edge Bayesian inference techniques for use with the cross-correlation method to measure precise  abundances and temperature.  He leads a research group that specialises in infrared high-resolution spectroscopy using various ground-based telescopes.

Jens Hoeijmakers

Jens Hoeijmakers is an associate senior lecturer at Lund Observatory in Sweden.  He led the discovery of iron and titanium in the exoplanet KELT-9b in 2018, which inspired several research groups around the world to engage in the hunt for metals in ultra-hot Jupiters.  He leads a research group that specialises in high-resolution spectroscopy using various ground-based telescopes, to answer fundamental questions about the compositions and climates of the atmospheres of hot exoplanets.
