Multifilter Time-series Observations of Eleven Blue Short-period ATLAS Variable Stars
The Astronomical Journal, 2023 Eleven periodic variable stars were observed photometrically through two to four filters from the set UBVR _C I _C . Phase-folded data for each star cover full cycles of variation.

Classification of periodic variable stars with novel cyclic-permutation invariant neural networks [PDF]
Monthly notices of the Royal Astronomical Society, 2021 We present Cyclic-Permutation Invariant Neural Networks, a novel class of neural networks (NNs) designed to be invariant to phase shifts of period-folded periodic sequences by means of ‘symmetry padding’.
