Abstract: We are carrying out a high-resolution (R∼21,500), H-band survey of B[e] stars of all types via the Apache Point Observatory Galactic Evolution Experiment (APOGEE) spectrograph, a high-resolution (R∼22,500) instrument operating in the H band between 1.515–1.695 μm. Although APOGEE is normally connected to the 2.5 m Sloan Digital Sky Survey (SDSS) telescope in multi-fiber mode, a long fiber link allows it to be used with the New Mexico State University (NMSU) 1 m telescope in single-fiber mode. Our goal is to observe all northern B[e] stars with H-band magnitudes < 10, and our sample of APOGEE-observed B[e] stars currently consists of 6 objects that have all been observed multiple times with APOGEE+2.5 m, and 23 objects that have each been observed once with APOGEE+1 m. The subtypes are well-represented thus far: unclB[e] 7/29, sgB[e] 4/29, HAeB[e] 7/29, cPNB[e] 2/29, symB[e] 9/29. We present preliminary results from the survey, including plots of the spectra, discussion of line identifications, and comparison of H-band line profile morphology among the subtypes.
