1. The visibility of stellar transients in the Galactic Centre
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/AstrofysikAbstract : A semi-analytical simulation was developed to evaluate the K-band magnitudes of Red Giants [0.96 - 1.02 M⊙] orbiting the supermassive black hole in the galactic centre. The model assumed star formation between 10-12 Gyrs ago and by following the IMF and applying a random age condition, a stellar population was created. READ MORE

2. An Infrared Stellar Thermometer: Exploiting IGRINS Spectra
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : Using the infrared (IR) spectral range when measuring stellar spectra is beneficial compared to using the optical range mainly when observing distant stars through the dust dense interstellar regions in the Galactic mid-plane. Methods to determine stellar parameters from IR spectra are, however, not fully developed yet because technological difficulties in creating reliable IR detectors have slowed the advance of such methods.

3. Heat Export from Supermarkets : Refrigeration Systems Field Measurements and a Techno-economic Analysis
University essay from KTH/EnergiteknikAbstract : Supermarkets have a high energy demand where almost half of the energy is used within the refrigeration system. The refrigeration system utilises a cycle where heat is taken and rejected. The rejected heat could be recovered and utilised for other purposes, such as covering internal heating demand or be exported to other facilities. READ MORE

5. 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
