Details on Acronym: MPCM
MPCM (MYStIX Probable Complex Member) Write:<<MPCM JHHMMSS.ss-DDMMSS.s>>
<<MPCM JHHMMSS.ss-DDMMSS.sa>> N: 31784 Object:PMS* (SIMBAD class: YSO = Young Stellar Object) Note:MYStIX (Massive Young Star-Forming Complex Study in Infrared and X-ray) is an archive survey of 20 massive star forming regions in the Galaxy at distances from 0.4 to 4 kpc. It combines new catalogs constructed from three observatories - Chandra X-ray Observatory in the X-ray band, UKIRT/UKIDSS in the near-infrared, and Spitzer Space Telescope in the mid-infrared - using sophisticated statistical methods to produce new reliable (but not complete) catalogs of pre-main sequence stars. This MPCM sample includes pre-main sequence members of the star forming complexes ranging from Class I protostars to Class III weak-line T Tauri stars with ages ∼0.1 to 5 Myr. MPCM is the most comprehensive catalog obtained to date for young stars in massive star forming regions.
The MPCM catalog will be published as an electronic table in the following paper submitted to Ap J Supplements: Identifying Young Stars in Massive Star-Forming Regions for the MYStIX Project, Patrick S. Broos, Konstantin V. Getman, Matthew S. Povich, Eric D. Feigelson, Leisa K. Townsley, Tim Naylor, Michael A. Kuhn, R. R. King, Heather A. Busk
The MPCM designation is closely tied to the proposed designation, MIRES (MYStIX Infrared Excess) stars. Note that the MYStIX project generates other (often very large) tables of intermediate data products that we do not believe require IAU designations. Eric Feigelson is the coordinator of the MYStIX project and is the contact for consultation on the proposed acronyms.
"a" or "b" suffixes are appended to distinguish very closely spaced MPCM stars.
7 papers are submitted to ApJSuppl describing MYStIX procedures and intermediate results leading to the MPCM sample. 10-15 science papers are planned for the 2013-15 period.
