  "abstract": "We present a homogeneous Hubble Space Telescope/Advanced Camera for Surveys F555W and F814W time-series census of variable stars in two M101 disk fields, using a uniform multiband reduction and reproducible variable-selection workflow for nearby supernova host galaxies. Supplementary archival F555W epochs are used only to refine selected long-period solutions. Candidates are selected with Lomb–Scargle period searches, Fourier light-curve modeling, two-band consistency statistics, artificial-star-test photometric corrections, and mode-aware Cepheid refinement. The final catalog contains 1417 variable-star candidates, including 1102 secure fundamental-mode and 78 secure first-overtone classical Cepheids. Of these secure Cepheids, 420 are newly identified relative to the B. J. Shappee & K. Z. Stanek catalog. The catalog also contains luminous candidates outside the classical Cepheid locus. We release the catalog and source-level two-band light curves for studies of Cepheid physics, stellar variability, and distance-scale applications.",
