The search for legitimate Taurus members to date has been limited by sky coverage as well as the challenge of distinguishing members from field interlopers. The Wide-field Infrared Survey Explorer has recently observed the entire sky, and we take advantage of the opportunity to search for young stellar object (YSO) candidate Taurus members from a ∼260deg2 region designed to encompass previously identified Taurus members. We use near- and mid-infrared colors to select objects with apparent infrared excesses and incorporate other catalogs of ancillary data to present a list of rediscovered Taurus YSOs with infrared excesses (taken to be due to circumstellar disks), a list of rejected YSO candidates (largely galaxies), and a list of 94 surviving candidate new YSO-like Taurus members. There is likely to be contamination lingering in this candidate list, and follow-up spectra are warranted. Description: In the context of Rebull et al. (2010ApJS..186..259R), we assembled a substantial multi-wavelength database, spanning Sloan u through Spitzer/MIPS 160um (with some X-rays) for point sources throughout the Taurus region. We use that catalog as the core for our analysis here, updating it with confirmed Taurus members from, e.g., Kenyon et al. ( and Luhman et al. (2010ApJS..186..111L) outside of our original Spitzer map. We have also searched SIMBAD (and literature references therein) for known galaxies and other contaminants in this vicinity. Our Taurus Spitzer Survey spanned ∼44deg2 (figure 1). WISE data acquisition and reduction are discussed in Wright et al. (2010AJ....140.1868W), Jarrett et al. (2011, ApJ, submitted), and in the Explanatory Supplement to the WISE Preliminary Data Release Products. There are four WISE bands, with central wavelengths at 3.4, 4.6, 12, and 22um, and a spatial resolution of 6" (12" at 22um). File Summary:

Note (1): Note added by CDS: In table 2 (Rejected YSO), the Name "TYC1823-680-1" (04 11 22.762 +26 52 43.35, J2000) is very doubtfully linked to WISE J041121.83+293320.5. Note (2): b = Object identified in Rebull et al. (2010ApJS..186..259R) as a candidate Taurus member, but discussed there as needing additional data to confirm/refute it as a Taurus member.
