SUMMARY:How rare is our Solar System? Probing the formation and evolution 
 of planetary systems - Dr. Joshua Lovell\, University of Cambridge

DESCRIPTION:Stars are born with gas-rich protoplanetary discs that typical
 ly survive for a few million years before dispersing\, after which they ar
 e left with the planetary bodies that formed within their protoplanetary s
 ystems. In our Solar System\, this process resulted in a diverse string of
  terrestrial planets\, gas- and ice-giants\, and two belts of `planetesima
 ls' (the Asteroid Belt and the Edgeworth-Kuiper Belt). Recent surveys in o
 ur Galaxy have revolutionized our understanding of the abundance of such p
 lanetary system components elsewhere with the detection of 1000s of main s
 equence planets\, 100s of `debris discs' (massive analogs of the Asteroid 
 and Kuiper belts) and even greater numbers of protoplanetary discs around 
 pre-main sequence stars where planets and planetesimals are either still f
 orming\, or yet to do so. \nAlthough the formation of planets and planetes
 imals is now understood to be the rule rather than the exception\, many of
  the discs and planets observed appear unlike those in our Solar System: t
 he details connecting young protoplanetary discs to the main sequence plan
 etary systems in which life may emerge remain unclear. In this talk\, I wi
 ll explore the origins and diversity of planetary systems\, and connect th
 ese to the most recent research and observations of planetesimal belts and
  debris discs.
