TL;DR: In this paper, a sample of 28 well-known spectroscopically-identified magnetic Ap/Bp stars, with weak, poorly-determined or previously undetected magnetic fields, was used to explore the weak part of the magnetic field distribution of Ap/bp stars.

TL;DR: In this article, the authors observed stars in open clusters and stellar associations of known ages, and used Zeeman Doppler imaging to characterize their complex magnetic large-scale fields.

TL;DR: The POLLUX database of synthetic stellar spectra as mentioned in this paper provides an unprecedented coverage of the entire Hertzsprung-Russell diagram and is used for the construction of theoretical spectral libraries helpful for stellar population synthesis.

TL;DR: In this paper, the magnetic field at the surface of 48 red giants selected as promising for detection of Stokes V Zeeman signatures in their spectral lines was investigated using the least-squares deconvolution method.

TL;DR: In this paper, the second part of a study investigating the evolution of large-scale surface magnetic fields in this critical time period was presented, where the authors observed stars in open clusters and stellar associations with known ages between 120 and 650 Myr, and used spectropolarimetry and Zeeman Doppler Imaging to characterize their large scale magnetic field strength and geometry.
