VizieR Online Data Catalog: Multiwavelength photometry of RCB stars (Montiel+, 2018)
Abstract
We have combined multiwavelength observations, which range from the UV to the submillimeter, in order to construct the most comprehensive spectral energy distributions (SEDs) of our sample R Coronae Borealis (RCB) stars. Photometry was done on the Spitzer and Herschel images in order to generate SEDs for the stars in our sample. Many different programs have been written to perform automated aperture and PSF photometry. We used the automated aperture routine Source Extractor (SExtractor; Bertin & Arnouts 1996A&AS..117..393B). The power of SExtractor is in its many tunable parameters that allow the user to maximize the program to perform photometry on their desired objects, whether they be point source or extended. SExtractor also provides robust post-run ancillary products such as residual, background, object, and aperture images in addition to performing aperture photometry on any given input images. We performed Monte Carlo radiative transfer (MCRT) modeling of the SEDs for the stars in our sample to better constrain the morphology and physical parameters of the dust surrounding these objects. We used the fully 3D MOnte CArlo SimulationS of Ionized Nebulae (MOCASSIN; version 2.02.70) code (Ercolano et al. 2003MNRAS.340.1136E, 2005MNRAS.362.1038E, 2008ApJS..175..534E)
