论文摘要
与以前的太空传播调查相比，过境系外行星调查卫星（TESS）提供了一种独特而新的方法来观察太阳系对象。尽管它的主要任务避免了黄道平面的附近，但太阳系碎片磁盘的尺度高度足够大，足以将各种小体种群放置在视野中。在本文中，我们介绍了小型太阳系体苔丝观测值的光度分析的第一个数据释放，重点是观察到的主要皮带小行星和Jovian Trojan种群的亮端。该数据释放称为TSSYS-DR1，包含9912光曲线，并以均匀的方式获得和提取，并将具有明确基本旋转特征的物体数量增加了三倍，即据报道准确的周期和振幅。我们的目录清楚地表明，旋转周期较长的物体的数量肯定被所有以前的地面调查所低估了，至少是一个数量级。
Compared with previous space-borne surveys, the Transiting Exoplanet Survey Satellite (TESS) provides a unique and new approach to observe Solar System objects. While its primary mission avoids the vicinity of the ecliptic plane by approximately six degrees, the scale height of the Solar System debris disk is large enough to place various small body populations in the field-of-view. In this paper we present the first data release of photometric analysis of TESS observations of small Solar System Bodies, focusing on the bright end of the observed main-belt asteroid and Jovian Trojan populations. This data release, named TSSYS-DR1, contains 9912 light curves obtained and extracted in a homogeneous manner, and triples the number of bodies with unambiguous fundamental rotation characteristics, namely where accurate periods and amplitudes are both reported. Our catalogue clearly shows that the number of bodies with long rotation periods are definitely underestimated by all previous ground-based surveys, by at least an order of magnitude.
