Abstract:
Thanks to modern technology — wide-field detectors, high computing power, massive data storage, and robotic observation—it is possible to obtain many asteroid light curves within a short period of time. Therefore, several important applications can be conducted on asteroids in a more comprehensive way. For instance, the interior structure which can be studied through the spin-barrier and the odd objects called super-fast rotator, the mechanisms that change asteroid spin state can be learned through the spin-rate distribution, and binary asteroid discovery….etc. I will talk about our asteroid time-series survey using wide-field facility, like the PTF/ZTF, the PS1, and the Subaru HSC, and what we have learned so far.
