Scientific paper

We are requesting Chandra ACIS-S imagery of MWC 480, a 7 Myr old Herbig Ae star with an accretion rate of 1E-8 solar masses/yr, intermediate between younger, accreting stars and older stars with transitional disks. The proposed integration will allow us to better delineate the evolution of X-ray activity in Herbig Ae stars, testing the hypothesis that the L_x is correlated with accretion signatures, rather than originating in coronal emission associated with a decaying dynamo. MWC 480 is also associated with a parsec-scale bipolar outflow, HH 728, with a 50" long counterjet which terminates in large, bright Herbig-Haro (HH) knot which will permit us to test models for X-ray production in HH knots over a wider range in outflow parameters than has been done to date.
