Infrared measurements such as from the Infrared Astronomical Satellite (IRAS) all-sky survey and the Midcourse Space Experiment (MSX) Galactic plane survey have been used to statistically distinguish between different types of objects. In particular, two-color diagrams characterize Asymptotic Giant Branch (AGB) stars with different circumstellar shell opacity and thickness, and whether the source is oxygen- or carbon-rich in nature (Van der Veen & Habing 1988, A&A 194, 125; Sjouwerman et al. 2009, ApJ 795, 1554).
We present two-color diagrams for AGB stars using infrared data from the AKARI satellite all-sky survey (e.g. Ishihara et al. 2010, A&A 514, A1) and created categories analogous to those for IRAS and MSX two-color diagrams. Our system specifically selects for circumstellar envelopes that are conducive in sustaining SiO maser emission. About 200 new sources were identified in the AKARI data.
This research was supported by the Research Experience for Undergraduate Program of the National Science Foundation, and was completed at the National Radio Astronomy Observatory in Socorro, New Mexico.
