SUMMARY OF SEQUENCE NUMBER 200048
Title: X-RAYS FROM THE RHO OPHIUCHI YOUNG STAR CLUSTER
Observer: FEIGELSON
Subject Category: Normal Stars and WD
Seq: 200048 ObsId: 00623
Long-term Plan bin: no LTS bin
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.
