Title: Spectroscopic follow-up observations of the AKARI T Tauri star candidates around the Taurus region

Abstract: Using AKARI Mid-Infrared All-Sky Survey, we propose new survey of T Tauri stars (TTSs) which are known to have the circumstellar disk. Since X-ray observations such as ROSAT revealed that many TTSs are located outside the natal cloud, some TTSs are thought to be still hidden. We selected the field of a 1800-square-degree region toward the Taurus-Auriga star forming region. Using known TTSs in the region, we developed new photometric criteria to extract TTS candidates. These candidates, however, might be contaminated by some Asymptotic Giant Branch (AGB) stars or galaxies. Hereafter, we need optical spectroscopy to confirm whether they are TTSs or not with H(alpha) emission line and Li\sc i absorption line. We request five nights with KPNO 2.1m/GoldCam Spectrograph. Once we confirm them, we will discuss the properties of circumstellar disks of TTSs.
