摘要:

本文报道了仙王座-仙后座恒星形成区十颗弱线金牛座T星自转周期的观测和测定结果。2007年6月至2008年5月期间,在耶拿大学天文台使用卡塞格伦-望远镜-照相机(CTK)进行了观测。得到的周期范围为0.49天和5.7天之间,典型的弱线和后T金牛星。

英文摘要:

We report on observation and determination of rotational periods of ten weak-line T Tauri stars in the Cepheus-Cassiopeia star-forming region. Observations were carried out with the Cassegrain-Teleskop-Kamera (CTK) at University Observatory Jena between 2007 June and 2008 May. The periods obtained range between 0.49 d and 5.7 d, typical for weak-line and post T Tauri stars.
