Overview

The Extension of HOPS Out to 500 ParSecs (eHOPS) project used archival data to survey all the major star forming molecular clouds within 500 pc of the Sun, except Orion (which was surveyed by HOPS). The first eHOPS data release covers the Aquila molecular clouds (d ~ 436 pc), and the second eHOPS data release adds the Auriga, Cepheus, Chamaeleon, CrA, Lupus, Musca, Ophiuchus, Perseus, and Pipe molecular clouds. For every source detected in the Herschel/PACS bands, the eHOPS catalog contains 1-850 micron SEDs assembled from 2MASS, Spitzer, Herschel, WISE, and JCMT/SCUBA-2 data. eHOPS compares the SEDs to a grid of radiative transfer models to constrain the luminosities, envelope densities, and envelope masses of the protostars. If you use eHOPS data, please cite both the journal article Pokhrel et al. (2023) and the dataset Digital Object Identifier (DOI): 10.26131/IRSA553. Last updated: 2023-10-24 Jump to documentation.
