SUMMARY:The formation and survival of planets: easier to grow but harder t
 o keep alive - Dr. Farzana Meru (ETH Zurich)

DESCRIPTION:The large number of extra-solar planets discovered over the la
 st two decades shows the existence of a huge diversity in their properties
 .  For these planets to be observed\, their growth and survivability in th
 eir parent circumstellar discs are very important to understand.  I will f
 irstly focus on the initial growth of dust in discs.  I will present a new
  physically-motivated model for dust growth and show that growth can occur
  to larger sizes than seen previously.  Once planets form\, they will inte
 ract with their parent disc.  Upon doing so\, they will open up gaps\, whi
 ch is a crucial stage for planet survivability.  I will present some recen
 t results which show that gap-opening by planets appears to be harder than
  previously thought and will discuss the implications for observations and
  theoretical models.
