Target RA (J2000): 76.7312088012695 and deg Target Dec (J2000): 10.9980697631836 and deg Gaia GMag: 9.68 Programme ID: CH_PR140069 Programme Manager: SZABO PI of observing programme: Benz Title of programme: Axis 3 - Photometric Transients in Dusty Debris Disks Abstract: We observe systems with warm dust disks regardless to the orientation of the disk but with positive detections of photometric transients from the disk with TESS. The targets will be selected from the results of Ansdell et al 2020 and Gaidos et al. 2022 in respect to the expected efficiency of CHEOPS observations and if possible simultaneously to TESS observations. The simultaneous CHEOPS+TESS multiband data will give us the first two-band space photometry of scattering dust in distant solar systems. [truncated! Please see actual data for full text]

J2000坐标系下的目标赤经：76.7312088012695 度，J2000坐标系下的目标赤纬：10.9980697631836 度，盖亚G星等（Gaia GMag）：9.68，项目编号：CH_PR140069，项目主管：SZABO，观测项目首席研究员（Principal Investigator，PI）：Benz，项目名称：“Axis 3 — 尘埃碎屑盘的光度暂现源研究”。摘要：我们将针对拥有暖尘埃盘的天体系统开展观测，观测不限制圆盘的空间取向，但需具备TESS（凌日系外行星巡天卫星，Transiting Exoplanet Survey Satellite）探测到该圆盘产生光度暂现源的有效探测结果。目标源将从Ansdell等人2020年与Gaidos等人2022年的研究成果中遴选，遴选依据为CHEOPS（系外行星特征卫星，Characterizing ExOPlanets Satellite）的观测预期效率，并尽可能与TESS观测同步进行。同步获取的CHEOPS与TESS多波段数据，将为我们获取遥远系外恒星系统中散射尘埃的首个双波段空间测光数据集提供支撑。[已截断！完整文本请查阅实际数据集]
