  2. 16. A Cosmic Quest for New Worlds. Characterising Exoplanet Signals via Radial Velocity and Transit Photometry

    Author : Iskra Georgieva; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Exoplanet; transits; radial velocities; planetary systems;

    Abstract : Since the first unambiguous detection of a planet around a Sun-like star, the interest in the new and exciting field of exoplanets has grown immensely. New and exciting developments are seen at a pace unparalleled for most subfields of astronomy. READ MORE

  4. 17. Astrophysical impacts on habitable planetary systems

    Author : Giorgi Kokaia; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Finding life on a planet other than the Earth would easily be one of the greatest discoveries of all time, particularly so if it is found outside our Solar System. To do so, we must understand the conditions required for life to emerge and develop. READ MORE

  5. 18. The role of ice in planet formation

    Author : Katrin Ros; Astrofysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Planetbildning; Protoplanetära skivor; Planet formation; Protoplanetary discs;

    Abstract : As stars form, they are surrounded by a disc composed of gas, dust and ice – the protoplanetary disc, where solids grow from micrometre-sized dust to planets. Small dust grows readily by collisions. READ MORE

  6. 19. Studies of Gas Disks in Binary Systems

    Author : Miguel de Val Borro; Pawel Artymowicz; William Benz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Astronomy; Astronomi; Astronomy; astronomi;

    Abstract : There are over 300 exoplanets detected through radial velocity surveys and photometric studies showing a tremendous variety of masses, compositions and orbital parameters. Understanding the way these planets formed and evolved within the circumstellar disks they were initially embedded in is a crucial issue. READ MORE

  7. 20. Extrasolar Kuiper and asteroid belts Modelling far-infrared dust emission

    Author : Joachim Wiegert; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stars: binaries - Stars: circumstellar matter - Infrared: stars - Infrared: planetary systems - Submillimeter: stars;

    Abstract : The first detections of circumstellar dust emission were announced in the mid 1980s. Direct observations of the edge-on disc of beta Pictoris provided evidence that the dust was part of possible planetary systems. About a decade later, in 1995, the first confirmed extrasolar planet around a main sequence star (51 Pegasi b) was announced. READ MORE
