A Spectroscopic Survey and Data Reduction of Young Fields Stars

In this paper, the authors present a high-resolution spectroscopic observations for a sample of 12 young solar-type stars near the Sun. All observational data were reduced using Image Reduction and Analysis Facility package in the standard fashion, including image trimming, bias subtraction, flat-field division and spectrum extraction, etc. Among these 12 young solar-type stars, the authors find three Weak-line T Tauri stars. They also find lithium depletion took place during PMS evolution for the sample stars. The result support predict by Piau and Turck-Chieze that the surface Li depletion will take place during PMS evolution for low-mass stars.
