A search for magnetic Ap stars in young open clusters using the ESO VLT
Abstract
We report results of an ongoing search for magnetic Ap stars in young open clusters using the ESO VLT and FORS1 spectropolarimeter. New magnetic field detections have been obtained for 19 stars, including a -9 kG magnetic field detected in the very young Rosette Cluster member NGC 2244-334 (a longitudinal field intensity second only to that of Babcock's star). In particular, we demonstrate robust exceptions to the proposal that Ap stars acquire their magnetic fields only after completing a substantial fraction of their main sequence evolution.
