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 …

Magnetic fields are present in a wide variety of stars throughout the HR diagram and play a
role at basically all evolutionary stages, from very-low-mass dwarfs to very massive stars …

We investigate the evolution of the relative angle between the stellar rotation axis and the
circumstellar disc axis of a star that forms in a stellar cluster from the collapse of a turbulent …

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 …

Magnetospheric accretion models predict that matter from protoplanetary disks accretes onto
stars via funnel flows, which follow stellar magnetic field lines and shock on the stellar …

We examine the long-term spectroscopic and photometric variability of EX Lupi and TW Hya,
studying the presence of stable accretion and the role it plays in the observed variability …

Stars form by accreting material from their surrounding disks. There is a consensus that
matter flowing through the disk is channelled onto the stellar surface by the stellar magnetic …

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 …

We present the analysis of 16 classical T Tauri stars (CTTSs) using LAMOST and TESS
data, investigating spectral properties, photometric variations, and mass accretion rates. All …

From observations collected with the ESPaDOnS spectropolarimeter at the Canada–France–
Hawaii Telescope (CFHT) and with the NARVAL spectropolarimeter at the Télescope …
