Research Topics and Publications 

A total of 524 scientific publications, of which 259 are in refereed scientific journals and 57 are invited reviews.
They deal mainly with the following topics:
Solar and heliospheric physics : Observations and theory of solar magnetism and convection − solar variability and its influence on the Earth, in particular the Sun-climate connection − structure of the solar atmosphere − coronal loops and oscillations − helioseismology − coronal holes and the fast solar wind − solar activity in historic and pre-historic times.
Stellar physics : Theory and observation of stellar magnetism and the associated activity − stellar rotational evolution − stellar imaging.
Gravitation : Astronomical tests of the equivalence principle and of alternative theories of gravity.
Radiative transfer : Radiative transfer of polarized light − theory of contribution and response functions− inversion techniques.
Atomic and molecular physics : Theory of the molecular Zeeman and Paschen-Back effects− Landé factors of atomic and molecular lines.
Other topics : Heliospheric modulation of galactic cosmic rays – protoplanetary discs – techniques for detecting extrasolar planet transits – stellar oscillations – development and application of waveletbased techniques.
