Scientific paper

The 4-30 Myr age range is particularly important in the life of pre-main sequence stars. It is in this age range where disks dissipate, as evidenced by a decrease in infrared excess emission arising from disks. Giant planets are expected to form in this age range, and the possible link between planet formation and disk dissipation is presently one of the most studied topics in star and planet formation. The dissipation of disks must have profound and testable consequences for the X-ray emission in this age range. Yet we are still lacking information on the early evolution of the X-ray emission in pre-main sequence stars. We therefore propose to make ACIS-I observations of fields in four 4-10 Myr clusters: NGC 7160, Tr 37, 25 Ori, and Ori OB1b.
