SUMMARY:The Impact of Photo-ionization Feedback on Massive Star Formation 
 - Nina Sartorio (University of St Andrews)

CONTACT:Catrina Diener
DESCRIPTION:A fundamental unanswered question in star formation is how mas
 sive stars (of masses ~ 8 Msun or higher) acquire their mass.\n The onset 
 of nuclear fusion in these stars occurs long before the star has reached i
 ts final mass.\n Therefore\, accretion must somehow continue even after th
 ese stars are emitting copious amounts of ionizing UV radiation. \n In thi
 s talk we explore some of the challenges we face in massive star formation
  and analyse the effect of photo-ionization \n on accretion disks\, as see
 n in recently preformed in high-resolution 3D radiation-hydrodynamics simu
 lations\; thereby verifying in \n which scenarios photo-ionizing feedback 
 may lead to a dissolution of the disk and which scenarios it may allow acc
 retion to continue
