Round 6 - C-WAYS (Cool, Wise, And Young Stars)

Abstract
All stars originate from clouds of interstellar gas, but the mechanism
responsible for formation can vary dramatically depending on the cloud
and its environment. For example, if a cloud is massive enough that
the gas pressure can no longer support it, gravitational collapse will
occur without any external help. In triggered star formation,
however, the collapse of a cloud is initiated by external pressure
from a nearby star, supernova, or even collision with another cloud.
When the external pressure is a shock or ionization front, it pushes
away the lower density material faster than the higher density core
material. When the external source is bright stars, it can illuminate
the rims of the cloud. Energy from nearby stars not only causes bright
rimmed clouds (BRC) to be visible at optical wavelengths, but may also
provide an impetus for triggered star formation. We propose to use
infrared excess to search for candidate young stellar objects (YSOs)
using newly released Widefield Infrared Survey Explorer (WISE) data in
three such BRCs, all of which are in regions of known star formation:
BRC 27 (with many known young stars), BRC 34 (a less dense star
forming region), and BRC 38 (with many known young stars). The Spitzer
Archival data was studied by Johnson et al. (2012; a 2011 NASA Ipac
Teacher Archive Research Program [NITARP] team) and Rebull et al.
(2012, in prep) for BRC 27 and BRC 34 and by Choudhury et al. (2010)
for BRC 38, providing verification for data analysis and results. We
will study the larger region around each of these BRCs using WISE
data. We will also process and analyze serendipitous Spitzer data
found for these three regions. Based upon our analysis, and in
combination with existing data in the literature, we propose to look
at the properties of previously identified YSOs as well as identify
new YSOs.
