A detailed spectroscopic analysis of the open cluster NGC 5460
L. Fossati, C. P. Folsom, S. Bagnulo +5
Within the context of a large project aimed at studying early F-, A- and late B-type stars we present the abundance analysis of the photospheres of 21 members of the open cluster N…
Magnetic fields in M-dwarfs: quantitative results from detailed spectral synthesis in FeH lines
D. Shulyak, A. Reiners, S. Wende +3
Strong surface magnetic fields are ubiquitously found in M-dwarfs with mean intensities on the order of few thousand Gauss-three orders of magnitude higher than the mean surface ma…
Investigation of magnetically sensitive FeH lines
Sebastian Wende, Ansgar Reiners, Andreas Seifahrt +2
M-type stars exhibit strong magnetic fields towards decreasing effective temperatures. The measurement of these fields is complicated due to missing indicators. Molecular FeH lines…
The extraordinary complex magnetic field of the helium-strong star HD 37776
Oleg Kochukhov, Andreas Lundin, Iosif Romanyuk +1
The early-type chemically peculiar stars often show strong magnetic fields on their surfaces. These magnetic topologies are organized on large scales and are believed to be close t…
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…
