DOI: 10.1007/s10511-024-09835-0
Abstract: Reanalyzing contact binaries with space-based photometric data and investigating possible parameter changes can yield accurate samples for theoretical studies. We investigated light curve solutions and fundamental parameters for twenty contact binary systems. The most recent… read more here.

DOI: 10.1038/s41550-025-02562-2
Abstract: Stellar activity is fundamental to stellar evolution and the formation and habitability of exoplanets. Magnetic surface activity is driven by the interaction between convective motions and rotation in cool stars, resulting in a dynamo process.… read more here.

DOI: 10.1093/mnras/staf1481
Abstract: Ultrafaint dwarf (UFD) galaxies are dominated by dark matter, the distribution of which may be inferred from the kinematics of that galaxy’s stellar population. Star-by-star observations are available for the satellite UFD galaxies of the… read more here.
