The search for magnetic fields in mercury-manganese stars
V. Makaganiuk, O. Kochukhov, N. Piskunov +7
We performed a highly sensitive search for magnetic fields on a large set of HgMn stars. With the aid of a new polarimeter attached to the HARPS spectrometer at the ESO 3.6m-telesc…
The HARPS polarimeter
Frans Snik, Oleg Kochukhov, Nikolai Piskunov +8
We recently commissioned the polarimetric upgrade of the HARPS spectrograph at ESO's 3.6-m telescope at La Silla, Chile. The HARPS polarimeter is capable of full Stokes spectropola…
Observations of solar scattering polarization at high spatial resolution
F. Snik, A. G. de Wijn, K. Ichimoto +3
The weak, turbulent magnetic fields that supposedly permeate most of the solar photosphere are difficult to observe, because the Zeeman effect is virtually blind to them. The Hanle…
