A dominant magnetic dipole for the evolved Ap star candidate EK Eridani
This article investigates the magnetic field of the late‐type giant EK Eri. The authors give arguments supporting the view that EK Eri is the descendant of a magnetic Ap star. It is often suspected that magnetic stars in advanced stages of evolution have Ap star progenitors. This investigation presents one of the first concrete pieces of evidence that the magnetic field remains detectable after Ap stars evolved away from the main sequence.
