  2. 1. Circumstellar Debris Disks : Observational Studies of Cold Dust and Gas Emission in Planetary Nurseries

    Author : Ricky Nilsson; Alexis Brandeker; Mark Wyatt; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; circumstellar disks; debris disks; Kuiper belts; planet formation; submillimeter imaging; photometry; coronagraphy; integral-field spectroscopy; Astronomy; astronomi;

    Abstract : Planetary systems form in disks of gas and dust surrounding newborn stars. The young circumstellar environment is characterized by frequent collisions between rocky bodies, leading to a continuous production of small dust grains. READ MORE

  4. 2. Impact of feedback on the ISM of extreme starburst galaxies : The case of Haro 11

    Author : Veronica Menacho Menacho; Göran Östlin; Armando Gil de Paz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Galaxies; stellar feedback; ISM; Integral field spectroscopy; Astronomy; astronomi;

    Abstract : Blue compact galaxies (BCGs) are compact, metal-poor, starbursting galaxies with characteristics similar to what is expected for the young high-redshifted galaxies. BCGs are among the most active in producing a large number of massive star clusters, each containing thousands of massive stars. READ MORE

  5. 3. Sources and fate of plastic particles in northern European coastal waters

    Author : Therese Karlsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; plastic pollution; microplastics; method development; polyethylene; FTIR spectroscopy;

    Abstract : Plastics are integral parts of our lives and have allowed for important technological leaps within society. However, an unwanted consequence of our current consumption of plas-tics is marine plastic pollution and in order to reduce its impact we need to understand its sources and fate patterns. READ MORE

  6. 4. The Kinematics of Blue Compact Galaxies - Gas and Stars

    Author : Thomas Marquart; Uppsala universitet; []
    Keywords : ;

    Abstract : Blue Compact Galaxies (BCGs) are intensely star forming, gas-rich systems and their light is dominated by a young stellar population and nebular emission. Their irregular morphology suggests dwarf galaxy mergers as cause for the onset of the burst in star formation. READ MORE

  7. 5. Spectral modeling of nebular-phase supernovae

    Author : Anders Jerkstrand; Claes Fransson; Luc Dessart; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supernovae; nucleosynthesis; radiative transfer; massive stars; 1987A; IIP; supernovor; nukleosyntes; spektralmodellering; strålningstransport; massiva stjärnor; 1987A; IIP; Astronomy; astronomi;

    Abstract : Massive stars live fast and die young. They shine furiously for a few million years, during which time they synthesize most of the heavy elements in the universe in their cores. They end by blowing themselves up in a powerful explosion known as a supernova (SN). READ MORE
