21. The Milky Way and its Exoplanets
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : The detections of over 4000 exoplanets as of today has shown that they exist in a wide range of different configurations, otherwise known as architectures. Recently, studies have been made trying to link the environment of host stars to the architectures of their planetary systems and have found that the architectures of planetary systems may not necessarily be uniform in the Milky Way.

22. Planning Observations of Terrestrial ExoplanetsAround M Type Stars with CRIRES+
University essay from Uppsala universitet/Observationell astrofysikAbstract : In recent decades, thousands of exoplanets have been discovered. The next step is to characterize theobserved planets in terms of their radii, masses, density, physical conditions and composition of theiratmospheres. READ MORE

23. Effects of planetary radius contraction on scattering
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : The observed high orbital eccentricities of many giant exoplanets is thought to be the result of gravitational scattering between planets. Outcomes of planet-planet scattering can result in some planets being lost by ejections into interstellar space, or collisions between planets or with the star. READ MORE

24. Detecting exoplanets with machine learning : A comparative study between convolutional neural networks and support vector machines
University essay from Uppsala universitet/Institutionen för teknikvetenskaperAbstract : In this project two machine learning methods, Support Vector Machine, SVM, and Convolutional Neural Network, CNN, are studied to determine which method performs best on a labeled data set containing time series of light intensity from extrasolar stars. The main difficulty is that in the data set there are a lot more non exoplanet stars than there are stars with orbiting exoplanets. READ MORE

25. Implementing an Algorithm for Spectrum Extraction of Circumstellar Objects with High-Dispersion Spectroscopy
University essay from Stockholms universitet/Institutionen för astronomiAbstract : In this thesis project, we study the field of high-dispersion spectroscopy and methods for extracting the spectrum of circumstellar objects such as exoplanets from the combined signal of a stellar system. One of the only techniques for detecting absorption lines in exoplanetary atmospheres is to directly image a planet and record the reflected light. READ MORE
