A very active sun today with many solar RF bursts (radio wave emissions from the sun).

I'm happy to announce that I've been awarded a one-year #ESO studentship to work with Elyar Sedaghati and @JuliaVSeidel on #ESPRESSO 🔭
See you in August, #Chile! 🇨🇱❤️

This his how a high resolution #spectrograph, designed for #exoplanets studies, looks from the outside. A bit chamber, with isolation layers, tubes and warning signs #AstronomerLife #astronomy #NIRPS

#ELODIE is a #spectrograph that was able to measure the radial velocity of #stars via the #Doppler effect with a precision down to about 10m/s.
It is actually the successor of the #CORAVEL spectrograph with which Michel Mayor & Antoine Duquennoy studied the population of binary stars in the #solar neighborhood. #CORAVEL had a precision down to about 300m/s which is not enough to discover (most) exoplanets.
#ELODIE is thus a super coravel.

We also contacted the director of the Canada-France-Hawaii #Telescope #CFHT, to use the new #spectrograph there, called #SPIRou. He explained us (in short) that our observation was during dark time (near new Moon), so the telescope should be used for faint, extragalactic targets, not for #exoplanet stuff. ❌
