  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. 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

  5. 3. High-contrast imaging of low-mass companions and debris disks

    Author : Ruben Asensio Torres; Markus Janson; Subhanjoy Mohanty; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Direct imaging; extrasolar planets; debris disks; planet formation; high angular resolution; Astronomy; astronomi;

    Abstract : The search for exoplanets, i.e., planets orbiting other stars than the Sun, is a relatively new research field, but has already established itself as one of the most prolific and intriguing areas of astronomy. READ MORE
