Overview

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.

Reviews

The book's strengths are in the juxtaposition of stellar and solar imaging and the quality of its nine chapters. ... Cartography of the Sun and the Stars is a fine resource for graduate students and postdocs or for anyone interested in this important developing field for which the best is yet to come. (Harold A. McAlister, The Observatory, Vol. 137 (1256), February, 2017)
