论文摘要
自2013年12月在2013年12月重新激活以来，使用该观察结果，我们的自动化管道候选对象和较小的候选物品，近地进行了两种频段的热红外调查，以检测和表征小行星和彗星，以检测和表征我们的自动化管道候选对象，并报告了较小的候选对象，并在2013年重新启动，近地物体宽现场红外调查探险器（Neowise）航天器（Neowise）航天器（Neowise）航天器一直在进行两种频段的热红外调查。使用这些检测，我们从近地对象和主带小行星种群对每个对象进行每个对象的热建模以限制其大小。我们介绍了在调查的第四年中检测到的189个NEOS和5831 MBA的小行星直径的热模型，以及第五年的185个NEOS和5776 MBA。迄今为止，Neowise重新激活调查为957个独特NEOS提供了热模型表征。包括原始智慧调查的所有阶段包括在2010年至今之间表征的总数达到了1473个独特的NEO。
The Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft has been conducting a two-band thermal infrared survey to detect and characterize asteroids and comets since its reactivation in Dec 2013. Using the observations collected during the fourth and fifth years of the survey, our automated pipeline detected candidate moving objects which were verified and reported to the Minor Planet Center. Using these detections, we perform thermal modeling of each object from the near-Earth object and Main Belt asteroid populations to constrain their sizes. We present thermal model fits of asteroid diameters for 189 NEOs and 5831 MBAs detected during the fourth year of the survey, and 185 NEOs and 5776 MBAs from the fifth year. To date, the NEOWISE Reactivation survey has provided thermal model characterization for 957 unique NEOs. Including all phases of the original WISE survey brings the total to 1473 unique NEOs that have been characterized between 2010 and the present.
