SUMMARY:Exozodiacal clouds - the local environment of habitable planets -

DESCRIPTION:The search for habitable exoplanets continues\, but what do we
  know about the local environment in which these planets reside? This can 
 be probed by looking for circumstellar dust\, since habitable zone dust em
 its in the mid-infrared (at ~300K). Several stars have such dust disks tha
 t are known as exozodiacal clouds\, by analogy with the zodiacal cloud in 
 our own Solar System. The importance of these "exozodi" is two-fold. First
 \, this dust could outshine an Earth-like planet\, hindering the next gene
 ration of exo-Earth imagers. This is why NASA recently completed a survey 
 of the nearest ~40 stars\, motivated by the desire to identify those with 
 low levels of dust. However\, the exozodi that are detected provide vital 
 information on the comets and asteroids in their systems\, and the bombard
 ment of any habitable zone planet can have important consequences for its 
 atmosphere and the development of life. This talk will present what we kno
 w about exozodiacal clouds and the implications for habitable planets.\n\n
 The talk will be followed by refreshments outside the lecture theatre. \n\
 nThe talk will be at the usual location of Wolfson lecture theatre in the 
 Department of Chemistry. The entrance is the opposite side of the building
  to Bristol-Myers-Squibb Lecture theatre and is opposite the car park- sho
 wn by the red arrow on the map. https://map.cam.ac.uk/Department+of+Chemis

  membership (£7) and life membership (£12) can also be purchased at the 
 event – please bring cash. The talk will be followed by refreshments out
 side the lecture theatre.
