  16. Main results show two different groups: PhD A theoretical study of pulsations in extreme helium stars. • Unusual composition He > 98%  Point to an advanced stage of evolution … • Pulsations  Tool to constrain their dimensions Mass, Teff and composition Big Bear Solar Observatory

  17. Next Step : Spectroscopic observations: We hope to obtain a spectrum of the Earth as it would be observed from the space. ( Also applicable to the search of terrestrial-like extra-solar planets.) The Earthshine Project: • Photometric observations: With the aim of measuring variations on the Earth’s ALBEDO (or reflectivity) we observe the Moonshine and Earthshine in the Moon.

  23. Some Results Total Cloud Cover Low clouds variability is strongly correlated with the flux of GCR (Solar activity) Low Cloud Cover If this to be true almost all global warming could be explained by an increase in solar activity during the last century Big Bear Solar Observatory

  27. Develop the Digital Vector Magnetograph • The Sun has a general magnetic field, similar the that of the Earth. In addition, there are local concentrations of very strong magnetic fields, known as active regions, which generate solar activity. • This activity, which occurs in the form of sunspots, solar flares, Coronal Mass Ejections, etc. can release great amounts of energy which can shower the Earth with high energy particles, known as solar storms, which can effect communications, utility power grids, satellites, etc. • To enable solar astronomers to be able to predict the probability and severity of solar storms and to enable engineers to design systems that can survive the most damaging of these events, we must be able to determine the morphology of an active region’s magnetic field with high time and high spatial resolution. • The purpose of the DVMG is to measure the strength and direction of magnetic fields on the surface of the Sun with a high time cadence ( ~ 1 minute ) and a high resolution ( ~ 1 arc-sec ).
