Target RA (J2000): 180.844345 and deg Target Dec (J2000): 49.25123 and deg Gaia GMag: 10.543 Programme ID: CH_PR110045 Programme Manager: SERRANO PI of observing programme: Benz Title of programme: EXPLORE - ChOIs: CHEOPS Objects of Interest. Identifying non-TOI candidates with CHEOPS Abstract: We propose to perform CHEOPS transit photometry of non-TOIs i.e. small planet candidates detected in TESS light curves with a relatively low signal-to-noise ratio (S/N < 7). More specifically the program aims at 1) excluding false alarms and increasing the significance of the transit detection 2) identifying additional transiting planet candidates (aka ChOIs) in bright TESS systems already known to host a TOI 3) improving the transit ephemeris and parameters.

目标赤经（J2000坐标系）：180.844345 度；目标赤纬（J2000坐标系）：49.25123 度；盖亚（Gaia）G星等：10.543；项目编号：CH_PR110045；项目主管：SERRANO；观测项目首席研究员：Benz；项目名称：EXPLORE——CHEOPS目标天体（ChOIs, CHEOPS Objects of Interest）：利用CHEOPS甄别非TESS目标天体（TOI, TESS Object of Interest）候选体。本项目拟对非TOI天体开展CHEOPS凌星测光观测，此类天体指在TESS光变曲线中被探测到的、信噪比（S/N <7）相对较低的小型行星候选体。本项目的具体研究目标包括：1）排除假警报，提升凌星探测的显著性；2）在已知存在TOI的明亮TESS系统中，识别额外的凌星行星候选体（即ChOIs）；3）优化凌星历元与行星参数。[文本已截断，请查阅原始数据以获取完整内容]
