1. 1. N-body simulations of exoplanets and their moons

   University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Author : Lydia Schollmeier; [2024]
   Keywords : Physics and Astronomy;

   Abstract : The planet-planet interactions in a many-planet system cannot be analytically calculated. Instead, they have to be investigated by using an N-body simulation. I discuss three questions about the N-body interactions in planetary systems: The first two are on the system 55 Cnc, a system with five known planets around a K-type star. READ MORE

3. 2. Petrography of impactites from the Dellen impact structure, Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Robert Mroczek; [2023]
   Keywords : Dellen; Impact; structure; magnetite; apatite; shock waves; shock-metamorphic; features; Impactite; petrography; scanning electron microscope; SEM; geology; Earth and Environmental Sciences;

   Abstract : Identification and characterization of shock-metamorphic features in hypervelocity impact craters is important for our understanding of how shock waves interact with geologic materials and how impact craters form, which in turn is essential to our understanding of what role impact cratering played in the development of our solar system. Of particular interest are accessory minerals like apatite, which contains various volatiles that can affect the atmosphere of a body, or magnetite whose magnetic properties constitute a remote sensing indicator which allows us to study and understand the internal structures of distant bodies.

4. 3. Simulations of the Tenuous Upper Atmospheres of Exoplanets

   University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Author : Lucian Spitzner; [2023]
   Keywords : astronomy; astrophyics; exoplanets; transmission spectroscopy; magnetic fields; atmospheres; ions; Physics and Astronomy;

   Abstract : 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

5. 4. Automatic waste sorter : Automatic sorting of metal and non-metal objects

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Vishi Sharan; Merna Iskander; [2022]
   Keywords : Waste; Mechatronics; Micro controller; Inductive proximity sensor; Metal; Avfall; Mekatronik; Mikro kontroller; Induktiv närhets sensor; Metall;

   Abstract : Our earths resources are not endless, so it is important to avoid wasting our planets natural resources. Recycling metal saves 95% more energy than producing new metal from ore, which is why it is necessary to reuse metal. Waste sorting is very important in today’s modern society as the demand for metals is increasing at a rapid rate. READ MORE
