New Spectropolarimetric Measurements of HD 144941
Abstract
We report new spectropolarimetric measurements of the magnetic massive He-strong star HD 144941, which is the most extreme member of this class of stars in terms of surface helium abundance. Twelve epochs over a time span of 1.5 times the rotation period were observed with the FOcal Reducer/low dispersion Spectrograph 2 on the European Southern Observatory's Very Large Telescope in 2021 July and August, doubling the low-resolution spectropolarimetry data available for the star.
