Gyrochronology is a technique that uses rotation periods to infer stellar ages. However, the existing calibrators are mostly limited to young (< 2 Gyr) clusters. Novel constraints are needed at older ages. We enlighten this by using field wide binaries with main- sequence (MS) primaries and white dwarfs (WD) companions. We use binaries identified from Gaia data (Fig. 1), where the ages of the WDs are known from stellar modeling, and we assign them to their MS companions. To obtain new gyrochronology constraints, we aim to measure the rotation periods of the MS components by analyzing light curves from the TESS mission (Fig. 2). From our sample of over ~ 3,500 binaries, ~1/3 of the MS stars have at least 1 TESS sector of data. Our preliminary results illustrate that wide binaries have the potential to fill in unexplored domains in age-rotation relations. (Fig. 3). Our current research is focused on expanding the sample, particularly at longer periods and old ages.
