在Kepler/K2图象中预测太阳系物体的凌日:虚拟天文台服务SkyBoT的扩展

Prediction of transits of solar system objects in Kepler/K2 images: An extension of the Virtual Observatory service SkyBoT

摘要:

扩展空间任务开普勒/K2的所有领域都位于黄道之内。因此,许多太阳系的天体会定期地穿过K2恒星掩模。我们的目标是为整个社会提供一个简单的工具来搜索和识别开普勒偶然观察到的太阳系天体。在IMCCE托管的SkyBoT服务提供了一个虚拟天文台(VO)兼容的圆锥搜索,列出了在给定的时间在视场内存在的所有太阳系对象。为了及时生成这样的列表,星历表被预先计算,每周更新,并存储在关系数据库中,以确保快速访问。SkyBoT Web服务现在可以与Kepler一起使用。在10秒内就能识别并列出小视场(几角分)内的太阳系天体。生成整个K2视场(14°)的对象数据大约需要一分钟。SkyBot服务的这一扩展为挖掘用于太阳系科学的K2数据以及从恒星光度时间序列中删除太阳系天体开辟了新的可能性。

英文摘要:

All the fields of the extended space mission Kepler/K2 are located within the ecliptic. Many solar system objects thus cross the K2 stellar masks on a regular basis. We aim at providing to the entire community a simple tool to search and identify solar system objects serendipitously observed by Kepler. The SkyBoT service hosted at IMCCE provides a Virtual Observatory (VO) compliant cone-search that lists all solar system objects present within a field of view at a given epoch. To generate such a list in a timely manner, ephemerides are pre-computed, updated weekly, and stored in a relational database to ensure a fast access. The SkyBoT Web service can now be used with Kepler. Solar system objects within a small (few arcminutes) field of view are identified and listed in less than 10 sec. Generating object data for the entire K2 field of view (14°) takes about a minute. This extension of the SkyBot service opens new possibilities with respect to mining K2 data for solar system science, as well as removing solar system objects from stellar photometric time-series.
