The Cluster Environment of High Mass Protostars
Abstract
We present images and some initial results from Spitzer IRAC and MIPS observations of 49 candidate high mass protostellar objects (HMPOs) and their surrounding environments. These candidate HMPOs are objects in the lists assembled by Sridharan et al (2002) and Molinari et al (1996) that were not covered by the GLIMPSE, GLIMPSEII and MIPSGAL surveys, with a few additions. Our sample has the advantage of longer exposure times than the GLIMPSE and MIPSGAL surveys. The images were reduced and photometry was performed using IRACproc (Schuster et al 2006). Color-color and color-magnitude criteria adopted from Gutermuth et al (2009), were used to identify candidate class0/I and classII protostars around each of the HMPO candidates. We present IRAS09131-4723 as an example of this analysis. It revealed 22 class0/I and 59 classII protostars distributed around IRAS 09131-4723. We plan to search the library of models presented by Robitaille et al (2007) for each class0/I/II candidate found, and use the parameters taken from the best fitting models to test the classifications obtained from the color-color analysis. We also plan to study the clustering of low mass protostars around the HMPOs.
