Abstract: |
We combine high resolution spectro-polarimetric observations of
the cold active star ε Eridani obtained with HARPS, NARVAL and
CAOS (Catania Astrophysical Observatory Spectropolarimeter).
We develop a code for the measurement of the effective magnetic field
based on the slope method, and we measure the effective magnetic
field of ε Eri, reporting a periodical variation of
the longitudinal field of the star, which is probably
due to a dynamo process. |
