" The Asteroid Spin Rate Study Using Large Field Surveys -- the Big Data Collection and Analysis "

Chang, Chan-Kao (National Central University, Taiwan)


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 can be studied through the spin-barrier and the odd objects called super-fast rotator, the mechanisms changing asteroid spin-status 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 and the PS1, and what we have learned so far.

Seminars are also held at JAC, CFHT, and IfA.
