  1. 1. Spectroscopic model characterisation of hot exoplanet atmospheres

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Author : Elin Sandvik; [2022]
    Keywords : Transit method; Transmission spectroscopy; Exoplanets; Hot Jupiter; Modelling; Physics and Astronomy;

    Abstract : Hot Jupiters are gas giants under intense stellar radiation with short orbital periods of only a few days. Due to their large radii, hot temperatures, and large scale heights, hot Jupiters can be observationally characterised in detail through spectroscopy over an entire orbital phase. READ MORE

  3. 2. How Odd is Betelgeuse?

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Martin Oshaughnessy; [2020]
    Keywords : Betelgeuse; runaway stars; stellar evolution; binary interactions; Physics and Astronomy;

    Abstract : The role of massive stars (those with masses greater than eight solar masses) in the chemical enrichment of galaxies and renewed star formation forms an important field of fundamental research in modern astrophysics. The complex nature of massive star evolution produces formidable challenges in furthering our understanding of the processes driving massive star evolution. READ MORE

  4. 3. Deriving Geothermal Reservoir Properties from Tomographic Models

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Samantha Kim; [2019]
    Keywords : Geothermal reservoir; super-critical fluids; optimization; seismic tomography; effective medium model; Iceland; Geotermisk energi; seismisk; mediummodel; reservoir; spricktäthet; superkritisk vätska optimisering;

    Abstract : The effectiveness of the heat transfer in a geothermal reservoir strongly depends on its temperature, pressure and rock type. A porous and fractured rock is essential to provide a hot fluid circulation to a geothermal power plant. READ MORE

  5. 4. CARBONDIOXIDE FLUXES FROM A CONTROLLED BOREAL RIVER

    University essay from Mittuniversitetet/Avdelningen för ekoteknik och hållbart byggande

    Author : FRANK ARTHUR; [2018]
    Keywords : Carbon dioxide fluxes; Gas transfer Velocity; Turbulence; Eddy covariance; Stream flow; Wind speed; Global Carbon cycle; Latent and sensible heat fluxes.;

    Abstract : River, lakes and   streams account for more carbon dioxide emissions than all other freshwater   reservoirs together. However, there is still lack of knowledge of the   physical processes that control the efficiency of the air-water exchange of   CO2 in these aquatic systems. READ MORE

  6. 5. Analys av metanflöden från sjön Erken

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Ryan Mintz; [2016]
    Keywords : methane; transfer velocity; flux; waterside concentration; eddy covariance; Nyckelord: metan; utbyteskoefficient; flux; metankoncentration; eddy kovarians;

    Abstract : While it is not the most abundant greenhouse gas, a significant portion of the greenhouse effect is caused by methane. The amount of methane in the atmosphere is increasing, indicating that there is a continuous source of methane to the atmosphere. READ MORE
