Target RA (J2000): 73.795753 and deg Target Dec (J2000): 30.36649 and deg Gaia GMag: 11.72 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]

项目名称：轴3计划——尘埃碎屑盘的光度暂变源
摘要：我们将对拥有暖尘埃盘的天体系统开展观测，观测不局限于圆盘的空间取向，但需确保通过TESS（Transiting Exoplanet Survey Satellite，凌日系外行星巡天卫星）已明确探测到该圆盘产生的光度暂变信号。观测目标将从Ansdell等（2020）与Gaidos等（2022）的研究成果中遴选，遴选标准需结合CHEOPS（Characterising Exoplanet Satellite，系外行星特征卫星）的预期观测效率，且在条件允许的情况下，可与TESS观测同步开展。本次CHEOPS与TESS的同步多波段观测数据，将为我们提供遥远太阳系外散射尘埃的首个双波段空间测光数据。
