What precisely is a summer school and what exactly is it about? The former is fairly simple to answer. A summer school isn't like your typical "summer school" we are all used to hearing about. You know, the one for misguided children and those basically failing in their studies. Quite the opposite. It is for the mega-nerds of the world to go and learn as much as they can on a particular subject. Some schools last a few days, some months. This one is 5 days, so not too much of an information overload.
The latter is more difficult to answer. I know we will be exposed to pretty much every topic imaginable about low-mass stars and the transition to brown dwarfs. Well, not exactly all of them... but pretty close to it. There is some very interesting physics that goes on in this stellar mass regime, and plenty that hasn't yet been studied in detail. So maybe that answers the question I posed. It'll be more about learning the current state of the field in order to gain exposure to what is known and what still needs to be done, opening new research avenues. The lectures last all week, save a half day on Wednesday where we travel to l'Ile de Batz.
Oh, and yeah, the last remaining days of my trip will be spend touring around Brest. Might as well take a mini-vacation while I'm there! It should be a lot of fun, but also quite a bit of work, so the vacation will be well earned, in my opinion.
