| Popis: | We present high-precision light curves of several M- and K-type, active detached eclipsing binaries (DEBs), recorded with 2-minute cadence by the Transiting Exoplanet Survey Satellite (TESS). Analysis of these curves, combined with new and literature radial velocity (RV) data, allows to vastly improve the accuracy and precision of stellar parameters with respect to previous studies of these systems. Results for one previously unpublished DEB are also presented. 5 pages, 1 table, 2 figures, Proceedings of the IAU Symposium 354 "Solar and Stellar Magnetic Fields: Origins and Manifestations" (poster) |
