Abstract
In this work, a multi-line spectropolarimetric detection using an Eche lle spectrograph is described. The polarization of Zeeman effect is de tected by the use of more than 200 lines observed in the solar type st ar, HR1099. Using the statistics analysis in a sample of 200 lines, we found on the average a polarization signal of about 3 x 10(-4).
