Deep Generative Modeling of Periodic Variable Stars Using Physical Parameters [PDF]
Astronomical Journal, 2022 The ability to generate physically plausible ensembles of variable sources is critical to the optimization of time domain survey cadences and the training of classification models on data sets with few to no labels.

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.

Periodic Variable Stars Modulated by Time-varying Parameters [PDF]
Astrophysical Journal, 2022 Many astrophysical phenomena are time-varying, in the sense that their brightness changes over time. In the case of periodic stars, previous approaches assumed that changes in period, amplitude, and phase are well described by either parametric or ...

Periodic variable A-F spectral type stars in the northern TESS continuous viewing zone [PDF]
Astronomy & Astrophysics, 2022 The goal of our study is to provide a reliable classification of variability of A-F stars brighter than 11 mag located in the northern TESS continuous viewing zone. We also aim at thorough discussion about issues in the classification related to the data
