•  Research Contributions

* Observed 15 Total Solar Eclipses at ground, over seas, using aircrafts (including the Supersonic Concorde 001) and in space; models of F-corona and of coronal structures; spectra and polarization analysis; * Developed several solar IR experiments at Pic du Midi Observatory 1st absolute measurements of solar intensities at 18 to 24 microns- 1968; 1st sunspot photometry at 3.75 microns; * Developed IR photometry at the Sacramento-Peak Obs. VTT (1977); * Developed a prominence magnetograph on the largest existing coronagraph- 53 cm aperture- of the USSR Kislovodsk High Altitude Observatory (1980-82)and an IR solar photometer at the Crimean Observatory (1974-76); * P.I. of the space-borne experiment 'Night Sky Imaging' for the flight of the 1st French Spationaute on Saliout 7 (1982); co-I of PIRAMIG; * Developed the 1st mirror coronagraph at NSO/SP (1987); 1st optical coronal image ever made with a mirror coronagraph; * Co-I of the C2/Lasco coronagraph of SoHO (1988); design of the SWATH space-borne mirror coronagraph at NASA (1992); * P.I. of the CFHT-91 eclipse coronal experiment on Mauna-Kea to point the largest optical telescope ever used toward the Sun; best resolution ever achieved of an image of the W-L corona; movie of a coronal plasmoïd; * Performed 1st observations of SXR polar jet-lets on Yohkoh-96 at ISAS- Japan ; * Performed 1st measurements of the solar prolateness at NSO/Sacramento- Peak Observatory (1997-98) using coronagraphs and the VTT (DST); * co-I on the Solar Probe coronal exp-t of NASA (2000), of the Lyot proposal of CNES (2004)and of the ASPICS proposal(artificial eclipses in Space). * P.I. of several cooperative projects (2000-2006) to develop Astronomical facilities in Iran , Russia , Egypte and Angola . * Main adviser (directeur de these) of more then 10 PhDs
