(Proposal Title)
25 mum imaging of southern Herbig Ae/Be stars

(Abstract)
We propose to make 25 mum imaging observations of southern nearby Herbig Ae/Be 
stars (HAeBes) to probe the structure of the protoplanetary disks surrounding 
them. We have collected 25 mum images of northern nearby HAeBes using Subaru/
COMICS and succeeded to show the inner gholeh or gaps in some disks such as 
HD 142527 and AB Aur. Proposed observations are the extention of our 25 mum 
imaging survey to southern sources. These observations will allow us to 
complete our 25 mum imaging survey of nearby HAeBe stars in both hemispheres 
and also contribute to our understanding on the evolution of the 
protoplanetary disk structures, especially the inner rim of the outer disk and 
gaps, which should be related to the ongoing planet formation.
