    Long-term Lightcurves of M31 X-ray Sources
    M31 has been monitored by a Chandra GTO program, which used both the HRC and ACIS from 1999 to 2001 and a GO program, which used ACIS-S during 2000-2001. We...

    Long-term monitoring of {gamma} Dor stars (Cuypers+, 2009)
    gamma Dor stars are excellent targets for asteroseismology since the gravity modes present in these stars probe the deep stellar interiors. Mode identification...

    Long-term starspot activity on BH Virginis.
    The authors parameterize the photometric distortion waves in the short-period RS CVn system BH Vir by a dark, circular spot model for the active regions on the...

    Long-term variability in the quiescent X-ray transient V404 Cyg
    We present the results of optical and infrared photometry of the quiescent X-ray transient V404 Cyg during the period 1992-2003.

    Long-term Variation of Solar Activity by a Dynamo Based on Magnetic Flux Tubes
    We show that cyclic activity and Maunder-type grand minima can be explained by a dynamo driven by the instability of magnetic flux tubes in the overshoot layer...
