New 2025 transit timing for HIP 41378 f confirms large TTVs and is combined with prior data on planets d and e in an N-body model to update ephemerides and predict future transits.
PSR J2101-4802 is a transitional millisecond pulsar with a ~1-day orbit, 0.15 solar mass He-WD companion, and large orbital period derivative that links redback-like systems to detached binaries.
MCMC modeling of the O-C diagram for HT Cas indicates two circumbinary companions causing the long-term period variations, yielding a negative quadratic term consistent with standard CV evolution below the period gap.
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.
Updated O-C diagrams for Kepler-451 favor a circumbinary planet at 3.4 AU after removing likely magnetic signals, with other LTT terms possibly systematic or magnetic in origin.
