Descripción
Polarized light provides key information on the physical conditions and
geometry of astrophysical plasmas otherwise unattainable via
conventional spectroscopy. In particular, the remote sensing of solar
and stellar magnetic fields requires the measurement and rigorous
theoretical interpretation of polarization signals in atomic and
molecular lines, which are induced by various subtle physical
mechanisms. I will begin presenting a brief introduction to
``Astrophysical Spectropolarimetry'', emphasizing the importance of
developing diagnostic tools that take proper account of the Zeeman
Effect, optical pumping processes and the Hanle Effect. Only in this way
may we hope to investigate the strength and topology of stellar magnetic
fields in a parameter domain which ranges from at least milligauss to
many thousands of gauss. In the second part of the talk I will discuss
some interesting applications in solar magnetism, suggesting also what
type of collaborations between physicists and chemists could lead to new
advances in astrophysics.
