活跃小行星公民科学计划：概述与初步结果
The Active Asteroids Citizen Science Program: Overview and First Results
AI总结：
“活跃小行星”公民科学项目利用Zooniverse平台和DECam数据，动员约8,300名志愿者审查43万张图像，新发现15颗活跃小行星和1颗活跃半人马天体，并促成对已知活跃天体的新发现与重新分类。
摘要：
我们介绍了公民科学计划“活跃小行星”（Active Asteroids），并描述了由我们持续开展的项目所取得的发现。我们的NASA合作项目托管在Zooniverse在线平台上，于2021年8月31日启动，旨在让社区参与搜寻活跃小行星——即具有彗星状尾或彗发的 asteroids。我们还着手识别其他不寻常的活跃太阳系天体，如活跃的半人马小行星（Centaurs）、活跃的准希尔达小行星（quasi-Hilda asteroids）以及木星族彗星（JFCs）。活跃天体之所以稀少，很大程度上是因为它们难以识别，因此我们邀请志愿者协助我们在数百万张已知小行星图像中搜寻活跃天体。我们利用项目流水线生成了这些裁剪图像，该流水线使用了公开可用的暗能量相机（DECam）数据。自项目启动以来，约8,300名志愿者仔细审查了约430,000张图像，取得了显著成效，我们将在本文中对此进行描述。总体而言，我们识别出了15颗小行星和1颗半人马天体上此前未知的活动，这些天体曾被认为是非活跃的小行星。在这些小行星中，我们将4颗归类为活跃准希尔达小行星，7颗归类为木星族彗星，4颗归类为活跃小行星，其中包括1颗主带彗星（MBC）和3颗主带彗星候选体。我们还纳入了关于已知活跃天体的发现，这些发现由我们的项目促成，是科学发现的一个意想不到的途径。这些发现包括：在天体此前未知活跃的轨道时期发现其活动，以及基于我们的动力学分析对天体进行重新分类。
英文摘要：
We present the Citizen Science program Active Asteroids and describe discoveries stemming from our ongoing project. Our NASA Partner program is hosted on the Zooniverse online platform and launched on 2021 August 31, with the goal of engaging the community in the search for active asteroids -- asteroids with comet-like tails or comae. We also set out to identify other unusual active solar system objects, such as active Centaurs, active quasi-Hilda asteroids, and Jupiter-family comets (JFCs). Active objects are rare in large part because they are difficult to identify, so we ask volunteers to assist us in searching for active bodies in our collection of millions of images of known minor planets. We produced these cutout images with our project pipeline that makes use of publicly available Dark Energy Camera (DECam) data. Since the project launch, roughly 8,300 volunteers have scrutinized some 430,000 images to great effect, which we describe in this work. In total we have identified previously unknown activity on 15 asteroids, plus one Centaur, that were thought to be asteroidal (i.e., inactive). Of the asteroids, we classify four as active quasi-Hilda asteroids, seven as JFCs, and four as active asteroids, consisting of one Main-belt comet (MBC) and three MBC candidates. We also include our findings concerning known active objects that our program facilitated, an unanticipated avenue of scientific discovery. These include discovering activity occurring during an orbital epoch for which objects were not known to be active, and the reclassification of objects based on our dynamical analyses.
