China's Space Station Telescope to Image Cool Exoplanets

The Cool Planet Imaging Coronagraph (CPI-C) on the Chinese Space Station Survey Telescope (CSST) represents a significant step forward in exoplanet research. By directly imaging cool exoplanets in reflected light, CPI-C will provide valuable data on their physical parameters, such as effective temperature, surface gravity, radius, and mass. The use of step-transmission apodization and precise phase correction techniques is crucial for achieving the required contrast and suppressing diffraction and speckle noises. The mission's focus on exoplanets ranging in size from Neptune-like to Jupiter-like, located at separations of 0.5 to 5 AU from their host stars, complements other exoplanet surveys and expands the range of detectable exoplanets. The potential observation results will significantly contribute to our understanding of planet formation and evolution mechanisms. However, the technical challenges associated with achieving high contrast and precise phase correction in space are significant. The success of the mission depends on the performance of the CSST and the CPI-C instrument. Further validation and calibration of the instrument will be necessary to ensure the accuracy and reliability of the data.
