  1. 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!

  2. 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).

  3. 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 !

  4. 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.

  5. 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.

  6. 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 !

  7. #HIP41378 f #transit

    We are observing from the #HauteProvence observatory !!!!

    Conditions are sub-nominal, but at least we are collecting photons. Let's hope for the best. 🤞

  13. Just arrived at the #HauteProvence #observatory. This is the view from the catwalk of the 1.93m #telescope I will be using for the next 5 #nights, weather permitting.
    So far, the #sky is 🔵
    I love when it’s 🔵

    Tonight I will hunt for #exoplanets and start observing #HIP41378 🔭

    @JuliaVSeidel: how is your sky ? 🔵 I guess as well ?

  14. 🚨 Conférence 🚨
    J'organise demain apres-midi avec Pierre Henriquet (aka astroPierre) une #conférence en ligne sur les #exoplanètes 🌟 🪐 🔭 . Je serai en direct depuis l'#observatoire de #HauteProvence et vous ferai visiter la grande #coupole, le #télescope qui a permis la découverte de la première #exoplanète en 1995 ainsi que d'autres lieux auxquels le public n'a généralement pas accès. 👀

  15. We requested #ESO's director time on the #VLT ➡️ time granted on #ESPRESSO
    We requested time to the director of the #HauteProvence observatory ➡️ time granted on #SOPHIE
    We requested time to the director of the #CalarAlto observatory ➡️ time granted on the #CARMENES spectrograph ✅
    We contacted a colleague who use a telescope in India ➡️ time granted on #PARAS
    We contacted by a colleague in the #US who developed a new spectrograph ➡️ time granted on EXPRES ✅

  16. First, #European observatories:
    - #Wendelstein obs. 🟠
    - #SOPHIE / #HauteProvence 🟠
    - #CARMENES / #CalarAlto 🟢
    - #HARPS-N / #LaPalma 🟠

    The #weather #forecast (white means clouds, blue means rain) at the time of observations does not look very good. 🤞 for better than expected weather conditions.

    Calar Alto 🇪🇸 might still be OK.
