CARTOGRAPHY OF THE SUN AND THE STARS KARTONIERT...

The mapping of the surface of stars requires diverse skills  analysis techniques and advanced
modeling  i.e. the collaboration of scientists in various specialties. This volume gives
insights into new techniques allowing for the first time to obtain resolved images of stars. It
takes stock of what has been achieved so far in Chile  on the ESO VLTI instrument or  in the
States  on the CHARA instrument. In recent times interferometry  combined with adaptive optics
has allowed to reconstruct images of stars. Besides the Sun (of course) by now five stars have
been resolved in detail. In addition to interferometry  this book highlights techniques used
for mapping the surfaces of stars using photometry made by space observatories  Zeeman- and
Doppler Imaging  mapping the surface element abundances via spectroscopy. This book will also
take stock of the best images of the solar surface  made by connecting the differential
rotation to the underlying physical parameters derived from helioseismology. Recent
measurements of flattening of the solar surface by SDO showed that the Sun's shape is linked to
the rotation of the core. It is shown how such a result is generalizable to the stars.
