e/Exozodiacal dust

Information
has gloss	eng: Exozodiacal dust is the exozodiacal analog of zodiacal dust, the 1-100 micrometre-sized grains of silicate dust that fill the plane of the solar system, especially interior to the asteroid belt. As for the zodiacal dust, these grains are probably produced by outgasing comets as well as by collisions among bigger parent bodies like asteroids. Exozodiacal dust clouds are often components of debris disks that are detected around main sequence stars through their excess infrared emission. By convention, exozodiacal dust refers to the innermost and hottest part of these debris disks, within a few astronomical units from the star. The shapes of exozodiacal dust clouds can show the dynamical influence of extrasolar planets, and potentially indicate the presence of these planets . Dynamical models of the effects of planets on the dust can be made using numerical tools, such as the Collisional grooming algorithm. Because it is located near a star's habitable zone, exozodiacal dust can be an important noise source for the Terrestrial Planet Finder.
