Debris Disk

 * The formation and distribution of the planets in our Solar system is closely entwined with the early evolution of its debris disk (Lissauer 1993) which, despite many different lines of evidence, do not produce a clear picture. By studying debris disks with a range of stellar ages, however, an evolutionary picture can be formed (see the reviews of Wyatt et al. 2007; Meyer et al. 2007). [arXiv:1212.1459]

Famous Systems

 * Fomalhaut: d=7.7pc; A3V star; 440\pm40 Myr old (Mamajek et al. 2012)
 * About its debris disk and planet candidate: (Holland et al. 1998; Kalas et al. 2005; Quillen 2006; Kalas et al. 2008; Kenworthy et al. 2012)
 * Observations taken with the Herschel Space Observatory from 70micron to 500micron (Acke et al. 2012) show that there is an estimated 110 Earth mass cometary reservoir supplying the dusty grains that are directly detected at these wavelengths.
 * High angular resolution observations at 350 GHz taken with ALMA resolves the debris ring on one side of Fomalhaut (Boley et al. 2012).
