Classification of Periodic Variable Stars from TESS
The Astrophysical Journal Supplement SeriesThe number of known periodic variable stars has increased rapidly in recent years. As an all-sky transit survey, the Transiting Exoplanet Survey Satellite (TESS) plays an important role in detecting low-amplitude variable stars.

Candidate RR Lyrae Associated with the Ultrafaint Dwarf Galaxy Aquarius III
The Astronomical JournalWe report the search of RR Lyrae in the vicinity of a newly discovered ultrafaint dwarf galaxy, Aquarius III. Based on the known RR Lyrae catalogs and gri -band light curves retrieved from public archives, we identified a RR Lyrae with distance ...

Three-dimensional Reddening Maps of the Magellanic Clouds Constructed by RR Lyrae Stars
The Astronomical JournalWe present the first three-dimensional reddening maps of the Large and Small Magellanic Clouds (LMC and SMC) constructed using fundamental-mode RR Lyrae stars (RRab) from the Optical Gravitational Lensing Experiment (OGLE) survey.
