The 2 m aperture Chinese Space Station Telescope (CSST) is a major science project established by the Space Application System of the China Manned Space Program. The survey plans to image 17,500 square degrees of the sky at a resolution of 0.15" in NUV, U, G, R, I, Z and Y bands and take slitless spectra over the same area. The point-source 5s limiting magnitudes in G and R bands can reach 26 AB mag or higher. CSST will be equipped with 5 instruments including a survey camera, a terahertz receiver, a multichannel imager, an integral field spectrograph, and a cool planet imaging coronagraph. The survey camera is equipped with 30 9kx9k detectors for science observations, each with a filter or grating mounted above, a defocused 9kx9k detector for flux calibration in R band, eight 640x512 near-infrared detectors, fine guide sensors, and wavefront sensors. It is expected to start science operation around 2024 and has a lifetime of 10 years.
With its wavelength coverage and angular resolution, CSST offers scientific opportunities and a great legacy value that complement other forthcoming space-based and ground-based surveys. CSST is ideally suited for astrometric studies of objects fainter than 20th mag. CSST will extend Gaia's tomographic mapping of the Milky Way to much fainter magnitudes, adding positions, parallaxes, distance estimates, color-magnitude-based stellar parameter estimates, and extinction estimates. Making suggestions and evaluating their feasibility in the unique science opportunities in astrometry with CSST will be paramount before its launch, In addition, valid scientific cases and suggestions can in turn facilitate the establishment and adjustment of observational strategies.
Since CSST will not be launched until 2024, this Research Topic invites research contributions based only on simulation data. Research topics fitting the category of 'CSST Astrometry' include, but are not limited to:
1) Reference Frame in near infrared band
2) Wide angle binaries study and detection
3) Proper motion derivation in the crowded field
4) The stellar population studies in resolved stellar populations in nearby galaxies
5) The detection and study of tidal streams in our galaxy
6) Proper motion search for nearby moving groups of faint low-mass stars
7) Synergy with other surveys, such as Gaia, LSST, etc.
8) Astrometric microlensing events predictions
9) Solar system objects studies and Ephemeris
10) Detection of special objects using astrometric methods, such as black holes
11) Astrometric data analysis models, methods and strategies
12) Other suggestions
