As my grand'ma puts it, first work, then play. Because of her, you will mostly find here serious stuff, namely astrophysics. Maybe later you'll find more funny subjects...

What work ?

My Ph.D. thesis within Eros intends to look for faint stars of the Solar neighbourhood, a few dozens of light-year away at most. These faint stars can be either red or brown dwarfs, or white dwarfs. Lots of colours.... Those objects are small, small as Jupiter or the Earth, but massives as a tenth of the Sun for the former, or as half of the Sun for the latter. First the coolest of those objects are hardly known, and it is important to discover more of them, it is possible that they make up a significant part of the dark matter, that we detect through its gravitationnal effects but that we have not directly observed so far.

( NB: if you follow the links you'll see nice pictures from NASA,
and/or get informations about those astrophysical objects )

Some articles or talks present results I got so far.

Finally, you'll find some recent discouveries here. Last: none.
