【摘要】：應(yīng)用國(guó)家天文臺(tái)興隆觀測(cè)基地2.16 m望遠(yuǎn)鏡及其高色散光譜儀,對(duì)6顆弱發(fā)射線T Tauri型星(Weak-line T Tauri Stars.簡(jiǎn)稱WTTS)進(jìn)行了高色散光譜觀測(cè),計(jì)算了這些弱發(fā)射線T Tauri型星的鋰元素豐度,討論了這些弱發(fā)射線T Tauri型星鋰豐度和恒星自轉(zhuǎn)周期、光變幅度的關(guān)系.研究發(fā)現(xiàn):自轉(zhuǎn)較快的弱發(fā)射線T Tauri型星鋰豐度小于自轉(zhuǎn)較慢的弱發(fā)射線T Tauri型星鋰豐度;但是這些弱發(fā)射線T Tauri型星,其鋰豐度與恒星在V波段的光變幅度并沒有明顯的相關(guān)性.
[Abstract]:Using the 2.16m telescope and its high dispersive spectrometer at Xinglong observation Base of the National Observatory, the hyperdispersive spectral observations of six weak emission line T Tauri T Tauri stars. The lithium abundance of these weak emission line T Tauri stars are calculated. The relationship between the lithium abundance of these weak emission lines T Tauri stars and the rotation period of stars and the amplitude of light variation is discussed. It is found that the lithium abundance of the weak emission line T Tauri stars with faster rotation is smaller than that of the weak emission lines T Tauri stars with slower rotation. However, there is no obvious correlation between the lithium abundance of these weak emission line T Tauri stars and the amplitude of light variation in V band.
