Lauren BRC 27

I found one article, published in July of 2011, that is not on the list. The title is 2MASS Wide field extinction map. I skimmed it, don't know if there's anything useful in it yet. I will go back through SIMBAD again to be sure that I have completely scoured that source for new papers.

Science background and Context:

BRC 27 is a star forming region within the molecular cloud CMa R1, located at 07h03m39s -11d23m43s. This star forming region is believed to be a Radiation Driven Implosion (RDI) morphology, although what triggered the star formation is not certain at this time (Gregorio-Hetem et al, 2009). Previous works has identified stars using various techniques and different sources. Wiramihardja et al in 1986 used UBV photographic photometry, Sugitani et al in 1991 used IRAS sources. Soares and Bica in 2002 and 2003 determined a distance of 1.2 parsecs and an age of 1.5 Myr for the stars in BRC 27. The distance was consistent with the findings of Schevchenko in 1999. A wide field X-ray study of the CMa OB1/ R! star forming region done by Gregorio- Hetem et al. (2009) was conducted to find low mass YSO that may have been previously undetected. Their work found approximately 40 members near Z Ma ad approximately 60 members near GU CMa. Both of these regions are close to BRC 27. Morgan et al. used the Submillimeter Common User Bolometer Array (SCUBA) in 2008 to survey 44 bright-rimmed clouds to identify a dense core in BRC 27. Chauhan et al, in 2009 used BVIc photometry to compare the ages of stars inside and outside the rims. Their conclusions showed that there is evidence of an RDI mechanism. Chauhan et al used archival IRAC, but not MIPS data for BRC 27. The YSO candidates were based on near IR JHK colors. Rebull et al. in 2011 used the mid-IR IRAC and MIPS colors to survey BC 27 to identify 94 new YSO candidates. We will use WISE photometric data to survey the same region in search of other yet unidentified YSO candidates. If there are no new candidate YSOs, the WISE data survey will cover a larger region than the works mentioned above. It will also help to put the previous data into context by comparing the spatial resolution differences of the previous works mentioned in this section.

Education and Outreach:

Team Reedley College

A small group of college freshman and sophomores will meet weekly. For the first few weeks, the students will be instructed on the basics of star formation and stellar evolution. Once the students understand the basics, they will begin reading the appropriate journals and conduct web research for discussion. Once the data processing instruction has been completed, the students will work together and separately on the data analysis portion of the project.

The weekly meetings will introduce the students to: • Star formation mechanism and stellar life cycle • Spectral analysis • Black body curves • Photometry

In the fall of 2012, the weekly meetings will be include to the processing of data. --Novatne 14:51, 18 February 2012 (PST)
