Original SFO - Sugitani et al 1991
Survey of BRCs to describe the BRCs themselves and look for YSOs.
Palomar Sky Survey (PSS) and IRAS point sources.
44 BRCs found in Palomar Sky survey prints that had associated IRAS point sources where all found to have IRAS point sources that were good candidates for being YSOs. Tables/images exist for; HII region locations, PPS finding charts, BRC location charts, IRAS point source properties (12, 25, 60, 100 micron), BRC and point source descriptions and plots.
Questions to ask yourself as you read
Abstract, Intro and Summary
-what is the flow of all the types of nebulosity that they describe and the cause/effect relationship to star formation?
-how will the understanding of this cause/effect help us in our closer study of just three BRCs?
The Sample, Results
-how did the authors take advantage of Palomar Sky Survey Prints?
-how will this help future astronomers with their work?
-table 3 lists exactly one IRAS source for each BRC, where are the rest of the YSOs we expect to see?
Discussion
Although 15 of the IRAS point sources were catagoized as type I and “really are” YSOs, why are all 44 of the sources considered good candidates for YSOs?
Most recent paper - Ogura et al 2002
Looking for H-alpha emissions using grism spectroscopy to find previously undetected YSOs that do not have strong IR excess in order to collect more information on star formation in BRCs and contained HH objects, and further investigate small-scale sequential star formation (SSSSF).
Optical (H-alpha using grism spectroscopy), 2 MASS
Questions to ask yourself as you read
Introduction
-what is SSSSF and what is the evidence for supporting this hypothesis?
-what is grism spectroscopy and how does it help “fill in some holes” in terms of YSOs?
Images and Data
-what qualitative and quantitative information will be helpful to us in our study? List tables and images, highlighting information specific to our study.
H-alpha stars, HH objects and Discussion
-what did the authors find of interest in our particular BRCs?
-what evidence is given to support further multi-wavelength studies searching for YSOs?
