标题： Mount Suhora high cadence photometric survey of T Tauri-type stars

摘要： 高采样率多色观测的121颗前主序星的结果，这些观测数据来自北半球。 本调查的主要目的是探测由这些年轻恒星及其吸积诱导的热点被近距离行星和/或尘埃团块遮挡而引起的凌星信号。 尽管没有探测到行星凌星，但我们的数据允许确定一些T Tauri恒星的自转周期，表征在经典T Tauri型恒星中从几分钟到几天的时间尺度上运行的吸积过程，以及由尘埃弯曲盘引起的大型光变曲线下降。 显示英文摘要

摘要： Results of high-cadence multi-colour observations of 121 pre-main sequence stars available from the northern hemisphere are presented. The aim of this survey was to detect transit-like signatures caused by occultation of these young stars and their accretion-induced hot spots by close-in planets and/or dusty clumps. Although none planetary transits were detected, our data allow to determine rotational periods for some T Tauri stars, characterise accretion processes operating in classical T Tauri-type stars in time scales ranging from a few minutes to days, as well as the large-scale dips caused by dusty warped discs.
