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

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

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

    Författare :Thomas Marquart; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  5. 4. Spectral modeling of nebular-phase supernovae

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

    Sammanfattning : 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). LÄS MER
