SUMMARY OF SEQUENCE NUMBER 200073

Title: EXTENDED X-RAY EMISSION FROM MASSIVE STAR FORMATION REGIONS

Observer: CHURCHWELL

Subject Category: Normal Stars and WD

Seq: 200073 ObsId: 00446

Long-term Plan bin: no LTS bin

ABSTRACT

We propose to obtain images and spectra for the massive star formation regions (MSFRs) W3, G5.89, and G34.26 using the ACIS-I detector on AXAF. Our goals are to determine how common X-ray emission is from MSFRs and if the emission is generally extended and as hard as that observed toward W3. Further, we wish to use the high spatial resolution of AXAF to resolve the individual UC HII regions in the W3 complex. Observations of G5.89 and G34.26 will address the issues of how common extended, hard X-ray emission is from MSFRs, determine if FeXXV line emission is common and possibly strong enough to account for a significant fraction of the FeXXV disk emission from the Galaxy.
