Abstract (from CDS):

Using the Wide Field Grism Spectrograph 2 (WFGS2), we carried out slit-less spectroscopy, g'r'i' photometry, and slit spectroscopy on the L 1014 dense core. We detected three Hα emission-line stars. We interpret one as being a weak-line T Tauri star (WTTS) and the others as classical T Tauri stars (CTTS). Since their g'-i' colors and/or classified spectral types are consistent with those of T Tauri stars and two of them show less extinction than the cloud, these three stars are likely to be T Tauri stars associated with L 1014. Adopting an age range for T Tauri stars, 1-10Myr, the color-magnitude diagram suggests a distance of ∼ 400-900 pc, rather than the previously assumed distance, 200pc. This could strongly affect the mass estimate of L 1014-IRS, which is thought to be either a very young protostar or proto-brown dwarf.
