Most high-priority Habitable Worlds Observatory targets have measured stellar activity and rotation, but long-term magnetic activity cycles are known for fewer than 20% of them.

abstract
This paper describes the first part of the photometric data from the 9x9 deg ASAS cameras monitoring the whole southern hemisphere in V-band. Data acquisition and reduction pipeline is described and preliminary list of variable stars is presented. Over 1,300,000 stars brighter than V=15 on 40,000 frames were analyzed and 3126 were found to be variable (1046 eclipsing, 778 regular pulsating, 132 Mira and 1170 other, mostly SR, IR and LPV stars). Periodic light curves have been classified using the fully automated algorithm, which is described in detail. Basic photometric properties are presented in the tables and thumbnail light curves are printed for reference. All photometric data is available over the INTERNET at http://www.astrouw.edu.pl/~gp/asas/asas.html or http://archive.princeton.edu/~asas .

An ensemble ML framework achieves 90.7% morphology classification accuracy and R² values of 0.77–0.92 for key parameters on held-out test data, with external validation against OGLE and Kepler catalogs.
IZ Tel and UW Vir are oEA binaries with δ Sct primaries showing mass transfer, derived masses of 1.48/0.33 and 2.39/0.67 solar masses, and multi-frequency pulsations including combination modes.
