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.

我们提出了一个普查的12,060光谱的蓝色物体($(g-r)_0<-0.25$)在斯隆数字巡天(SDSS)数据发布8(DR 8)。作为数据发布的一部分,所有光谱都与恒星、星系和类星体的48个模板光谱进行了交叉相关,以确定最佳匹配。我们通过眼睛将蓝色光谱与SDSS DR 8中指定的模板进行了比较。其中10,856个物体与其指定的模板匹配,170个由于信噪比(S/N)低而无法分类,1034个被赋予新的分类。我们确认了7458颗DA白矮星,1145颗DB白矮星,273颗较为罕见的白矮星(包括碳、DZ、DQ和磁),294颗亚矮星O星,648颗亚矮星B星,679颗蓝色水平分支星,1026颗蓝色离散星,13颗激变变星,129颗白矮星- M矮星双星,36颗光谱与DO白矮星相似的天体,179个类星体和10个星系。我们提供了这些天体的两个表格,与模板匹配的样本光谱,显示按眼睛分组的所有光谱的图,以及显示每个分类的位置,颜色,视星等,自行等的诊断图。未来的调查将能够使用类似于我们识别的每个类别中的恒星的模板来自动分类蓝色恒星,包括罕见类型。
