Probable Association of T Tauri Stars with the L 1014 Dense Core

Using the Wide Field Grism Spectrograph 2 (WFGS2), we have carried outslit-less spectroscopy, g'r'i' photometry, and slit spectroscopy on the L1014dense core. We detected three Halpha emission line stars. We interpret one asweak-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 withthose 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 L1014.Adopting an age range for T Tauri stars, 1-10 Myr, the color-magnitude diagramsuggests a distance of ~400-900 pc, rather than the previously assumeddistance, 200 pc. This could strongly affect on the mass estimate of L1014-IRS,which is thought to be either a very young protostar or proto-brown dwarf.Comment: 5 pages, 5 figures, to be published in Vol.58, No.5, October 25, 200
