Elements: Enabling High Precision Citizen Science Photometry from Wide Field Color Images

该项目正在开发免费和开放源码软件和网络界面，用于从公民科学家用彩色数码相机收集的观测数据中提取高精度的恒星亮度测量值。大规模生产使这种相机比专业天文学家通常使用的单色探测器更便宜;消费者相机还具有许多内置功能，使其比专业探测器更易于操作和自动化。然而，彩色图像是特别具有挑战性的现有工具，由于交错的微过滤器应用到检测器像素，使颜色灵敏度。该项目将大大扩大能够为尖端科学做出贡献的公民科学家的数量：使用这些工具，公众可以追求许多额外的系外行星和可变星星项目使用高节奏，表示“高”之义对大部分或全部天空中的明亮恒星进行精确的测光，其成本仅为专业调查的一小部分。该项目正在与三个通过公民研究来追求系外行星科学的领先项目合作。观察：PANOPTES、系外行星观察和Unistellar网络。该软件将成为PANOPTES的数据处理管道，并被集成到系外行星观察和Unistellar管道中，确保其被三大全球公民科学家社区采用。 公民科学数据将用于搜索TESS卫星识别的仅一次凌日的候选行星的额外凌日、已知短周期系外行星系统和TESS凌日候选行星中的额外较长轨道周期行星的凌日以及已知的凌日。径向速度行星。任何被确认的行星都将围绕着从地球上看起来异常明亮的恒星运行，产生深凌，并且远离恒星。前两个性质使得这类行星特别容易使用最先进的空间和地面设施进行研究，和地球-这些行星的星星相互作用将比目前围绕类似明亮恒星的深凌行星群的典型情况弱得多。NSF高级网络基础设施办公室的这一奖项由NSF天文科学部门共同支持。该奖项反映了NSF的法定基金会的使命是履行其使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评价，被认为值得支持。

This project is developing free and open-source software and a web interface for extracting high-precision brightness measurements of stars from citizen scientist observations collected with color digital cameras. Mass production makes such cameras much more affordable than the monochrome detectors typically used by professional astronomers; consumer cameras also come with a host of built-in features which make them much simpler to operate and automate than professional detectors. However, color images are particularly challenging for existing tools due to the staggered microfilters applied to detector pixels which enable color sensitivity. This project will greatly expand the pool of citizen scientists able to contribute to cutting edge science: using these tools, the public can pursue numerous additional exoplanet and variable star projects using high-cadence, high-precision photometry of bright stars over much or all of the sky at a fraction of the cost of professional surveys.This project is collaborating with three of the leading projects pursuing exoplanet science through citizen observations: PANOPTES, Exoplanet Watch, and the Unistellar network. This software will become the data processing pipeline of PANOPTES and be integrated into the Exoplanet Watch and Unistellar pipelines, ensuring its adoption by three large global communities of citizen scientists. The citizen science data will be used to search for additional transits of candidates identified by the TESS satellite with only a single transit, transits from additional longer orbital period planets in both known short period exoplanet systems and TESS transit candidates, and transits of known radial velocity planets. Any identified planets will orbit stars that appear exceptionally bright from Earth, produce deep transits, and reside far away from their stars. The first two properties makes such planets particularly easy to study using state of the art space and ground facilities, and the planet-star interactions will be much weaker for these planets than is typical for the current population of planets with deep transits around similarly bright stars.This award by the NSF Office of Advanced Cyberinfrastructure is jointly supported by the NSF Division of Astronomical Sciences.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
