SUMMARY OF SEQUENCE NUMBER 200044

Title: X-RAYS FROM THE RHO OPHIUCHI YOUNG STAR CLUSTER

Observer: FEIGELSON

Subject Category: Normal Stars and WD

Seq: 200044 ObsId: 00619

Long-term Plan bin: 11-Apr-2000

ABSTRACT

The rho Ophiuchi cloud is one of the richest and nearest star forming regions with hundreds of young stellar objects (YSOs) representing all stages of early stellar evolution. It is a superb laboratory for the study of X-ray emission from YSOs with extensive multiwavelength data. AXAF observations will lead to insights concerning the dispersal of circumstellar disks, the impact of ionizing radiation and particles on disks, and the evolution of X-ray emission. We propose a mosaic of ACIS fields covering one square degree, designed to give a uniform sensitivity despite large changes in cloud extinction.
