1. The chemical evolution of the Milky Way: pushing APOGEE to higher precision and accuracy
University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenAbstract : In the recent decade, a rapid increase in all-sky spectroscopic surveys has occurred, and with it, the wealth of observational data and information on our Galaxy. Consequently, numerous detections of new structures, such as new open clusters, accreted and in-situ components, are discovered. READ MORE

2. Simulations of the Tenuous Upper Atmospheres of Exoplanets
University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenAbstract : Over the last decade, the interest in research on extraterrestrial planets has expanded dramatically. With the number of confirmed exoplanets having increased tenfold over the last ten years, we now know that many different types of exoplanets exist. READ MORE

3. Spectroscopic determination of stellar parameters to constrain atomic diffusion in the old open cluster M67
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : In an attempt to check published results on diffusion effects in M67 a non-LTE analysis is made on 28 high resolution FLAMES-UVES spectra of dwarfs and sub-giants around the turnoff point, where core hydrogen fusion halts. This analysis utilizes the software-suites LOTUS and iSpec to determine stellar parameters from equivalent-width measurements. READ MORE

4. Exploring the Diversity of Exoplanets
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : The search for extrasolar planets had been ongoing for many years when Mayorand Queloz discovered 51 Pegasi b in 1995. It was a giant gas planet similar to Jupiter, but with a larger radius and of only half of Jupiter’s mass. Theso called Hot Jupiter was observed to orbit its host star 7 times closer thanMercury is orbiting the Sun. READ MORE

5. Capture into mean motion resonance
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : Orbital or mean motion resonance (MMR) occurs when the orbital period ratio between two planets is close to a ratio of small integers. MMR can protect planets from collisions and affects the overall final architecture of the system. READ MORE
