  1. 16. Detailed analysis of the chemical composition of stars harboring Earth-like planets

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Lorena Acuña Aguirre; [2019]
    Keywords : Physics and Astronomy;

    Abstract : Context. The planet-metallicity correlation for gaseous giants is widely accepted through spectroscopic studies. However, whether a similar correlation exists for terrestrial planets is a debated subject. READ MORE

  3. 17. The fate of pebbles and planetesimals entering protoplanetary envelopes

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Emil Zadera; [2019]
    Keywords : Planet formation; planet; protoplanet; protoplanetary envelope; protoplanetary atmosphere; protoplanetary growth; planetary growth model; accretion rate; vapour blob; vapourblob; vapour planet; transport of water; water on planet; pebbles; planetesimals; pebble accretion; planetesimal accretion; meteors; ablation; fragmentation; sublimation; protoplanetary disk; MMSN; accretion window; accretion channel; accretion; destruction; disruption; terminal velocity; gas; gasflow; shearingbox; exoplanet; Physics and Astronomy;

    Abstract : Planetary embryos grow by the accretion of solid dust-material, ranging from cm- to m-sized pebbles up to km-sized planetesimals. However, the underlying size-distribution of the accreted material is poorly understood. READ MORE

  4. 18. Alkali Circulation in the Blast Furnace - Process Correlations and Counter Measures

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Joel Carlsson; [2018]
    Keywords : Alkali; coke; experimental blast furnace; top gas; mass spectrometry; multivariate analysis;

    Abstract : In blast furnace ironmaking one major challenge is to control and measure the alkalis circulating and accumulating in the blast furnace (BF). Alkali enter the BF with the primary raw material and will form a cycle where it is first reduced to metal at the lower parts forming gas. READ MORE

  5. 19. Process Simulation of Plasma Gasification for Landfill Waste

    University essay from KTH/Materialvetenskap

    Author : Tan Boon Hau; [2018]
    Keywords : landfill waste; RDF; plasma gasification; syngas;

    Abstract : The growing amount of landfill waste within the EU could pose a problem in the future should there not be any effective treatment methods. This study aims to investigate the performance of landfill waste in a plasma gasification process by simulating the process in ASPEN Plus. READ MORE

  6. 20. Nucleosynthesis in accretion disks around black holes

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Neige Frankel; [2017]
    Keywords : accretion disk; Nucleosynthesis; black hole; high energy; white dwarf tidal disruption; Physics and Astronomy;

    Abstract : Nucleosynthesis is the mechanism which produces new elements in nuclear reactions. Nuclear reaction rates are highly temperature dependant, and nuclear reactions take place in very hot environments. Current theories predict that the light elements such as hydrogen and helium were produced during the Big Bang. READ MORE
