Accretion through circumstellar disks plays an important role in star formation and in
establishing the properties of the regions in which planets form and migrate. The …

Cool stars like the Sun harbor convection zones capable of producing substantial surface
magnetic fields leading to stellar magnetic activity. The influence of stellar parameters like …

We investigate how the observed large-scale surface magnetic fields of low-mass stars (∼
0.1–2 M⊙), reconstructed through Zeeman–Doppler imaging, vary with age t, rotation and X …

This is the first in a series of papers in which we describe and report the analysis of a large
survey of Herbig Ae/Be stars in circular spectropolarimetry. Using the ESPaDOnS and …

Aims. This paper examines the outflows associated with the interaction of a stellar
magnetosphere with an accretion disk. In particular, we investigate the magnetospheric …

Zeeman–Doppler imaging studies have shown that the magnetic fields of T Tauri stars can
be significantly more complex than a simple dipole and can vary markedly between sources …

Mass loss from jets and winds is a key ingredient in the evolution of accretion discs in young
stars. While slow winds have been recently extensively studied in T Tauri stars, little …

Recent observations have shown that in many exoplanetary systems the spin axis of the
parent star is misaligned with the planet's orbital axis. These have been used to argue …

Context. The origin of the fossil magnetic fields detected in 5 to 10% of intermediate-mass
main sequence stars is still highly debated. Aims. We want to bring observational constraints …

The magnetic fields of young stars set their coronal properties and control their spin
evolution via the star–disc interaction and outflows. Using 14 magnetic maps of 10 classical …
