VizieR Online Data Catalog: Spitzer/IRS obs. of Magellanic carbon stars (Sloan+, 2016)
Abstract
Table 1 lists the 144 objects in the LMC and 40 in the SMC observed with the IRS (spectral coverage at 5-14um and 14-37um, respectively, with a resolution R~80-120) and identified as carbon stars. A variety of Spitzer observing programs contributed to the present sample of carbon stars (see Note 2 in table 1). We adopt distance moduli for the LMC and SMC of 18.5 and 18.9, respectively.
For all of our targets, we have constructed SEDs based on multi-epoch photometry in the optical, near-IR, and mid-IR from several surveys. The mid-IR data come from the SAGE survey of the LMC (Meixner et al. 2006, J/AJ/132/2268) and the SAGE-SMC survey for the SMC (Gordon et al. 2011AJ....142..102G)). The SAGE-VAR survey adds four epochs from the Warm Spitzer Mission at 3.6 and 4.5um for portions of the LMC and SMC (Riebel et al. 2015ApJ...807....1R). We also used additional epochs at 3.4 and 4.6um from the Wide-field Infrared Survey Experiment (WISE; Wright et al. 2010AJ....140.1868W) and the NEOWISE reactivation mission (Mainzer et al. 2014ApJ...792...30M). Near-IR photometry comes from the 2MASS survey, and the deeper 2MASS-6X survey provides a second epoch at J, H, and Ks (Cutri et al. 2012, II/281; Skrutskie et al. 2006, VII/233). Additional epochs come from the Deep Near-IR Survey of the Southern Sky (DENIS) at J and Ks (Cioni et al. 2000, II/228) and the IR Survey Facility (IRSF) at J, H, and Ks (Kato et al. 2007, II/288). In the optical, we relied on the Magellanic Clouds Photometric Survey (MCPS) at U, B, V, and I (Zaritsky et al. 2002, J/AJ/123/855; 2004, J/AJ/128/1606). DENIS adds data at I. Additional mean magnitudes at V and I in the LMC come from the OGLE-III Shallow Survey (Ulaczyk et al. 2013, J/AcA/63/1). Where possible, we replaced the V and I data with mean magnitudes from the OGLE-III surveys of the Magellanic Clouds, which also give pulsation periods and amplitudes (Soszynski et al. 2009, J/AcA/59/335; 2011, J/AcA/61/217). We also consider a Galactic control sample using spectra from the Short-Wavelength Spectrometer (SWS) on the Infrared Space Observatory (ISO); see section 2.5. (7 data files).- Publication:
