<p> Within this bachelor project, the 3D cloud structures of a range of exoplanets is calculated and analysed.
<p> This thesis analyses the cloud formation on exoplanets, which orbit a F-type host star.
The exoplanets are tidally locked, which causes a strong contrast
between the side of the planet facing the star and the side facing away from
the star. The cloud simulation is modelled using the StaticWeather model and the
dataset from hot Jupiters with an equilibrium
temperature of Teq = 1400 K up to a temperature of Teq = 2600 K compiled
by a 3D General Circulation Model (GCM). The differences between the two mixing
types (normal and scaled) and the two versions of GCM (old and new) are
explained.

<p>To get a better understanding of exoplanets and especially their atmospheres,
theoretical models have to be created. The aim of this thesis is to simulate the cloud
formation process on tidally locked Hot-Jupiters, which orbit a G-type host star.
The cloud formation process was modelled for planets with equilibrium temperatures
ranging from 2600 K to 1200 K in 200 K steps. For each planet, two mixing models
were considered and simulated. The findings of
this project suggest that planets with a lower equilibrium temperature have a more
prominent nucleation formation rate, more bulk growth and therefore have more cloud
particles. Planets with higher equilibrium temperature have clouds predominately on
the night side, with lower equilibrium temperatures the clouds exist all around the
planet.

<p> The Long Night of Research is an Austria wide event in which many research institutes and universities open their doors for the general public. The program is suitable for young and old, and many of the guests are families with kids from various ages. </br></br>
At the Space Research Institute of the Austrian Academy of Science, we prepared a full program including talks, guided tours through the labs, and interactive activities for kids. During this event, I had the pleasure to kick of the event with a <a href="docs/langenacht.pdf" target="_blank">presentation about exoplanets for kids</a>. The engagement of the audience was stunning and their previous knowledge of planets in our Solar System was detailed. It was a great pleasure to tell them more about exoplanets and to hopefully spark their interests in exoplanet science. After this, I presented the same topic for an older audience within three installments through the night. The whole event was a great success and showed the interest and engagement of the general public in space sciences.</p>

<p> Oriel Marshall is presenting her work to a group of teachers to motivate them to use her newly developed cloud formation lessons. To show the roots of her lessons in current exoplanetary research, Nanna Bach-M&oslash;ller and I present our current work. Nanna is presented recent aerosol experiments which she conducted in the laboratory of the University of Copenhagen. I presented the basics of 3D exoplanet climate modelling and why it is important to know about their clouds.<br />
Seeing the motivation of teachers to learn about new scientific concepts and their eager to add it to an already pack-full curriculum is inspiring. Conducting research on a PhD level somtimes feels disconnected from the real world, but through the work of Oriel and the engagement of teachers we are able to bring our research to students and the broader public. </p>

<p>Here on Earth, weather is one of the most important small talk topics, but what would we talk about if we were on an exoplanet? Thanks to state-of-the-art instrumentation and advanced modelling, we are beginning to understand the fascinating diversity of weather on planets outside of our own solar system.
<br />Exoplanet surveys like Kepler have discovered thousands of exoplanets, meaning, we are now aware of the large diversity of exoplanets that exist in our galaxy. The next step is now to characterise these exoplanets. With current state-of-the-art technology, we are already starting to gain insights into their atmospheres, and with upcoming instruments like the James Webb Space Telescope (JWST) we hope to deepen our understanding of these alien worlds.

<br />Some of the most fascinating objects discovered so far are Hot Jupiters: planets the size of Jupiter but with orbital periods of just days. These giant gas planets are tidally locked, which results in permanent day and permanent night sides. The temperature, winds and clouds on these planets are nothing like what we know from planets within our solar system and understanding them is the first step to understanding the diverse atmospheres of exoplanets.</p>
