  1. J'ai retrouvé la Haute-Provence et ses plateaux telle que ma mémoire me l'avait laissée. Quelques champs de lavande ont été délaissés au profit d'autres cultures. Comme chaque année, la région verdoie son plein avant la sécheresse estivale. Je retrouve la joie de la grimpe en falaise.

  5. Un groupe de lycéen•nes de Carpentras parodie la série #bref pour présenter leur projet #scientifique porté par ma collègue Sophia Sulis @LAM_Marseille. Ils ont observé un transit d’#exoplanete depuis l’#observatoire de #HauteProvence pour la mission spatiale #Ariel de l’#ESA.

    A voir absolument!

  7. This is the #ESO #picture of this week. It shows the 1.52m #telescope at #LaSilla #observatory 🇨🇱 observing the #MilkyWay thought the #dome's opening.

    This telescope is now retired after almost 30 years to study #stars, #galaxies, #comets and even #exoplanets.

    This telescope is the twin of the 1.52m telescope at #HauteProvence Observatory 🇫🇷 . Still used nowadays, the french brother has a new adaptive-optic (AO) test bench, 33 years after the first AO prototype for ESO (COME-ON).

  10. I would like to warmly #welcome all the #Astronomy & #Astrophysics enthusiasts who recently joined #Astrodon or another instance. Welcome to the #fediverse. 🤗

    #Mastodon is currently a bit slow because of the sudden increase in users doing their #twittermigration. I am sure it will get back to normal in no time.

    As a welcome gift 🎁 , I am posting below my #bestof #timelapse #video from the #LaSilla, #LaPalma, and #HauteProvence observatories.

    Enjoy !

  12. Although the #Nobel Prize 2019 was awarded to the 2 leading astronomers, the 51Peg b discovery was made possible thanks to a much broader team of technicians and engineers (here in 2005) from the #HauteProvence Observatory and the Marseille Observatory, especially André Baranne.

  15. All these optical elements can now be seen on the ground floor of the 1.93-m telescope at the #HauteProvence #Observatory (🇫🇷 ). Here are a few pictures of #ELODIE I took for you.

  18. To improve the radial velocity precision, #ELODIE had to be a much more stable instrument, in a temperature- and pressure-controlled environment which was not compatible with the dome.

    So, André Baranne (a french astronomer at Marseille Observatory who also built #CORAVEL in 1977) suggested to use optical #fibers to feed the stellar light from the #telescope to the instrument. We can see these fibers in orange in this picture of the bonnette, mounted on the 1.93-m telescope at #HauteProvence.

  21. The jump in precision between the #CORAVEL (300m/s) and the #ELODIE (10m/s) spectrographs was due to several achievements.

    CORAVEL was mounted directly on the back of the swiss telescopes at either the #HauteProvence or #LaSilla observatories. In such case, the instrument's #optical and #mechanical components are deformed by #temperature, #humidity and the position of the telescope. Such deformation was a clear limitation to the radial velocity precision.

  24. In 1995, the swiss #astronomers Michel Mayor and Didier Queloz discovered the first #exoplanet orbiting a #Sun-like #star: 51 Peg b. For that, they received the 2019 Physics' #Nobel Prize.

    This discovery opened a new field of research in #astronomy. It was based on #observations done with the 1.93m #telescope at #HauteProvence #observatory (🇫🇷 ) with the instrument #ELODIE.

  27. If you have 40s, give a look at this #timelapse #video I did a few years ago from the #HauteProvence #observatory. It shows the 1.93m #telescope I am currently using to hunt for #exoplanets. This is the very same telescope that allowed the discovery of 51 Peg b, the first exoplanet.

    The telescope doesn't have a laser guide star. The green laser is a LIDAR, dedicated to study the atmosphere.

  29. The night is getting to its end over #Europe. Here is the status of the #HIP41378 f campaign so far:
    - #HauteProvence observatory: we got ONE (likely out-of-transit) spectrum through a hole in the clouds
    - #CalarAlto: all-sky camera showed stars all the night. I've not heard back from the observatory yet, but it looks good
    - #LaPalma had lot of cirrus passing. Likely a killer for photometry, but OK for spectroscopy. 🤞

    Now, it's time for #ESO to start the show !
