Survey of period variations of superhumps in SU UMa-type dwarf novae. IX. The ninth year (2016โ2017)
Abstract Continuing the project described by Kato et al. (2009, PASJ, 61, S395), we collected times of superhump maxima for 127 SU UMa-type dwarf novae observed mainly during the 2016โ2017 season and characterized these objects. We provide updated statistics of the relation between the orbital period and the variation of โฆ
