The last decade has shown a surge in research on the Interacting Binary White Dwarf s (IB-WDs), or Helium CVs, also called AM CVn systems. We have witnessed long photometric campaigns, time resolved spectroscopy, UV and X-ray observations, and modell

The best method for identification of planetary forcing of the Earth's climate is to investigate pe- riodic variations in climate time series. Some natural frequencies in the Earth climate system seem to be synchronized to planetary cycles, and ampli

The Schwabe frequency band of the sunspot record since 1700 has an average period of 11.06 yr and contains four major cycles, with periods of 9.97, 10.66, 11.01 and 11.83 yr. Analysis of the O-C residuals of the timing of solar cycle minima reveals t

PG 1351+489 is one of the 20 DBVs ― pulsating helium-atmosphere white dwarf stars ― known and has the simplest power spectrum for this class of star, making it a good candidate to study cooling rates. We report accurate period determinations for

PG 2303+243 is a cool DA variable (also called ZZ Ceti) star with a rich pulsation spectrum and variable amplitudes. A mini-campaign involving six observatories yielded time-resolved photometric measurements of PG 2303+243 during the period 2004 Sept
