摘要:

柏林系外行星搜索望远镜是一个小口径、宽视场望远镜,专门用于时间序列光度观测。在德国陶滕堡的Thueringer Landessternwarte天文台的初始调试阶段以及随后在法国上普罗旺斯天文台的运行期间,靠近银道面的3.1 ° x 3.1 °环极场以(α,δ)=(02小时39米23秒,+52 °01 ' 46”)(J 2000.0),在2001年8月至2006年12月期间的52个夜间观测到。从观测到的32129颗恒星中,发现了145颗具有明显恒星变率的恒星,其中125颗是新发现的变星。对于五个明亮的物体,通过对光曲线进行建模来导出系统参数。

英文摘要:

The Berlin Exoplanet Search Telescope is a small-aperture, wide-field telescope dedicated to time-series photometric observations. During an initial commissioning phase at the Thueringer Landessternwarte Tautenburg, Germany, and subsequent operations at the Observatoire de Haute-Provence, France, a 3.1 ° x 3.1 ° circumpolar field close to the galactic plane centered at (α, δ) = (02h 39m 23s, +52° 01' 46") (J 2000.0) was observed between 2001 August and 2006 December during 52 nights. From the 32129 stars observed, a subsample of 145 stars with clear stellar variability was detected out of which 125 are newly identified variable objects. For five bright objects, the system parameters were derived by modeling the light curve.
