Bibiana Prinoth<p><a href="https://astrodon.social/tags/ExoAdvent" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ExoAdvent</span></a> - 16/12 </p><p>Are you ready for some bad weather? Storms and shattering rain? Then HD 189733 b is the planet for you! Horizontal rain is a given!</p>
Bibiana Prinoth<p><a href="https://astrodon.social/tags/ExoAdvent" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ExoAdvent</span></a> - 15/12</p><p>Let’s be honest, we cannot have a Christmas calendar without talking about at least one of the TRAPPIST-1 planets. I picked TRAPPIST-1 f because of its distance from the host star. Could you imagine living on a planet where there is one dayside and one nightside?</p>
Bibiana Prinoth<p><a href="https://astrodon.social/tags/ExoAdvent" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ExoAdvent</span></a> - 14/12 </p><p>Did you ever wish you could travel back in time to know how the world was before you were born? I certainly do! </p><p>Although it’s not really like time travel, exoplanets allow us to study planetary systems at different age stages. Today’s planet, 51 Eridani b, is thought to be a teenage version of Jupiter on an orbit similar to that of Saturn. It offers us to look how things could have been at earlier stages of the Solar System.</p>
Bibiana Prinoth<p><a href="https://astrodon.social/tags/ExoAdvent" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ExoAdvent</span></a> - 13/12</p><p>Recently, I spent a week of vacation in Puerto Rico. When I came across the new name of this planet, I just had to share it with you. HAT-P-26 b doesn’t have to suffer with its original name anymore!! Sometimes, planets get to be named by teams from different countries. What’s your favourite exoplanet and what would you name it?</p>
Bibiana Prinoth<p><a href="https://astrodon.social/tags/ExoAdvent" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ExoAdvent</span></a> - 12/12 </p><p>Things have been floating around a bit, so this one comes with a slight delay 🤫 May I introduce you to KELT-11 b, a target I would love to observe one day.</p>
Bibiana Prinoth<p><a href="https://astrodon.social/tags/ExoAdvent" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ExoAdvent</span></a> - 11/12</p><p>Another day, another planet! Behind number 11, we’ve got GJ 1132 b - an exoplanet that really likes to hide. It has been observed with many different instruments but we are still not sure about what’s going on in its atmosphere. For the years to come, I expect that we’ll spend more time figuring this out. May&amp;MacDonald+ 2023 made a very important point in their paper: observing only once will not be sufficient for these smaller planets!</p>
Bibiana Prinoth<p><a href="https://astrodon.social/tags/ExoAdvent" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ExoAdvent</span></a> - 10/12</p><p>I wonder if there have been bets amongst my friends/family/followers, when I am going to talk about my “baby” 🥹 WASP-189 b has been the planet I have been working with the most during my PhD, and I am proud to say that I am also the one who led the two papers detecting and confirming titanium oxide in its atmosphere. So today, I am a bit proud of myself 🤭I am currently working on another follow-up study, and hope to tell you more soon 🤭</p>
Bibiana Prinoth<p><a href="https://astrodon.social/tags/ExoAdvent" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ExoAdvent</span></a> - 9/12</p><p>Let's open the stage for HR 8799 b!<br>Together with its siblings, this system is just mind-blowing. It is one of the systems that has been discovered using direct imaging.<br>So no need for looking at how the star changes over time to indirectly detect your planet, but taking many 'pictures' are sufficient. The HR 8799 system is an all-time favourite! What do you think?</p>
Bibiana Prinoth<p><a href="https://astrodon.social/tags/ExoAdvent" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ExoAdvent</span></a> - 8/12</p><p>K2-18 b has been big in the media lately, because of some recent JWST observations. These have revealed methane absorption, an absence of waters. The authors also claim a detection of DMS (Dimethyl sulphide), but time will tell..</p>
Bibiana Prinoth<p><a href="https://astrodon.social/tags/ExoAdvent" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ExoAdvent</span></a> - 7/12</p><p>Today‘s planet is VERY hot! KELT-9 b is one of the - if not the - hottest exoplanet known today. Interestingly, we expect colder ultra-hot Jupiters to have clouds on the nightside (the side facing away from the star), but KELT-9b likes to be special. It is very efficient at redistributing the heat around the globe, so no clouds for it!</p>
Bibiana Prinoth<p><a href="https://astrodon.social/tags/ExoAdvent" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ExoAdvent</span></a> - 6/12</p><p>GJ 1214 b is definitely one to play hide-and-seek! Astronomers have been in a love-hate-relationship with clouds for a long time. Sometimes we hate them — for me especially when observing — sometimes we love them, because they tell an interesting story about the climate of an exoplanet’s atmosphere. I say hide-and-seek because GJ 1214 b is hiding its atmosphere under a thick cloud layer and only time will tell if we are going to be able to peek through this layer. 🤞🏻</p>
Bibiana Prinoth<p><a href="https://astrodon.social/tags/ExoAdvent" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ExoAdvent</span></a> - 5/12</p><p>So close and yet so far away! Proxima Centauri b - often just called Proxima b - is the closest known exoplanet to us. Yet, the distance to this exoplanet is 4.2 lightyears - so light takes 4.2 years to travel this distance. What might seem close, suddenly is not really that, and it is only the first step in imagining the immense size of the universe — and its emptiness… 🌌</p>
Bibiana Prinoth<p><a href="https://astrodon.social/tags/ExoAdvent" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ExoAdvent</span></a> - 4/12</p><p>We are sticking to the hot ones. WASP-121 b will always have a special place in my heart. Its temperature gives me a bit of Swedish <a href="https://astrodon.social/tags/lagom" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>lagom</span></a> vibes, because it is just about right for vanadium to exist in the gas phase, but titanium has no chance at surviving and gets washed away ☔️ Cool, isn't it?</p>
Bibiana Prinoth<p><a href="https://astrodon.social/tags/ExoAdvent" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ExoAdvent</span></a> - 3/12</p><p>55 Cancri e is probably one of my favourite non-hot Jupiter exoplanets. In my imagination, this planet is fully covered in lava with volcanoes that keep on adding more. Because 55 Cancri e is so close to its host star, the temperature on the dayside is expected to be around 2,700 K (2,430°C; 4,400 °F) on average. This is comparable to ultra-hot Jupiter temperatures! Kinda hot, right? 🔥</p>
Bibiana Prinoth<p><a href="https://astrodon.social/tags/ExoAdvent" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ExoAdvent</span></a> - 2/12</p><p>I think I'm on to something when I say that this exoplanet is a bit of a high flyer. Not only is it the first to be discovered using the transit method, but it's also the first one where scientists have been able to detect an atmosphere. This planet was only discovered in 1999 and in a way shows how young the field of exoplanets and exoplanet atmospheres actually is. We've come a long way since then, but there's still a lot more to do and I'm excited to be part of that task! 🪐</p>
Bibiana Prinoth<p><a href="https://astrodon.social/tags/ExoAdvent" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ExoAdvent</span></a> - 1/12</p><p>Kepler-22 b has been quite the catch in the media. Discovered already in 2011 by the Kepler spacecraft, Kepler-22 b seems to tick quite a few boxes for astronomers. In particular, it is located in the habitable zone and could theoretically sustain liquid water on its surface. We don't know that though... only once we manage to observe its atmosphere it will hopefully tell us more (bc we can’t go there bc even light takes 640 years to travel from Kepler-22 b to us) ⭐️🪐</p>
Bibiana Prinoth<p>For my outreach account on instagram, I am running an advent calendar introducing an <a href="https://astrodon.social/tags/exoplanet" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>exoplanet</span></a> a day. I call this calendar <a href="https://astrodon.social/tags/ExoAdvent" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ExoAdvent</span></a> and figured I could share it here too! ⭐️ 🌎 🪐 </p><p>A thread 🧵</p>
