Characterising the magnetospheric accretion process of DF Tauri's primary
K. Pouilly, M. Audard
The accretion process in young stellar objects (YSOs) is fundamental to the formation of stellar systems. This process governs the star's mass assembly, the transfer of angular mom…
Dissimilar magnetically driven accretion on the components of V4046 Sagittarii
Kim Pouilly, Marc Audard
Accretion of pre-main sequence stars (PMS) is a key process in stellar formation, governing mass assembly, influencing angular momentum conservation and stellar internal structure,…
Comparative study of small-scale magnetic fields on Boo A using optical and near-infrared spectroscopy
A. Hahlin, O. Kochukhov, P. Chaturvedi +12
Magnetic field investigations of Sun-like stars, using Zeeman splitting of non-polarised spectra, in the optical and H-band have found significantly different magnetic field streng…
Unraveling the binary nature of HQ Tau: A brown dwarf companion revealed using multi-variate Gaussian process
Kim Pouilly, Jérôme Bouvier, Evelyne Alecian
Context. Both the stellar activity and the accretion processes of young stellar objects can induce variations in their radial velocity (RV). This variation is often modulated on th…
A conclusive non-detection of magnetic field in the Am star o Peg with high-precision near-infrared spectroscopy
O. Kochukhov, A. M. Amarsi, A. Lavail +10
The A-type metallic-line (Am) stars are typically considered to be non-magnetic or possessing very weak sub-G magnetic fields. This view has been repeatedly challenged in the liter…
Accretion and magnetism on young eccentric binaries: DQ Tau and AK Sco
Kim Pouilly, Axel Hahlin, Oleg Kochukhov +2
The accretion and ejection of mass in pre-main sequence (PMS) stars are key processes in stellar evolution as they shape the stellar angular momentum transport necessary for the st…
Star-disk interactions in the strongly accreting T Tauri Star S CrA N
H. Nowacki, E. Alecian, K. Perraut +11
Aims : We aimed at constraining the accretion-ejection phenomena around the strongly-accreting Northern component of the S CrA young binary system (S CrA N) by deriving its magneti…
Stable accretion and episodic outflows in the young transition disk system GM Aurigae
J. Bouvier, A. Sousa, K. Pouilly +17
We investigate the structure and dynamics of the magnetospheric accretion region and associated outflows on a scale smaller than 0.1 au around the young transitional disk system GM…
Accretion process, magnetic fields, and apsidal motion in the pre-main sequence binary DQ Tau
Kim Pouilly, Oleg Kochukhov, Ágnes Kóspál +3
Classical T Tauri stars (CTTSs) are young stellar objects that accrete materials from their accretion disc influenced by their strong magnetic field. The magnetic pressure truncate…
Beyond the dips of V807 Tau, a spectropolarimetric study of a dipper s magnetosphere
Kim Pouilly, Jérôme Bouvier, Evelyne Alecian +6
We aim to characterize the magnetospheric accretion process in the young stellar object V807 Tau, one of the most stable dippers revealed by K2 in the Taurus star forming region. W…
Investigating the magnetospheric accretion process in the young pre-transitional disk system DoAr 44 (V2062~Oph). A multiwavelength interferometric, spectropolarimetric, and photometric observing campaign
J. Bouvier, E. Alecian, S. H. P. Alencar +13
Young stars interact with their accretion disk through their strong magnetosphere. We investigate the magnetospheric accretion process in the young stellar system DoAr 44. We monit…
Magnetospheric accretion in the intermediate-mass T Tauri star HQ Tau
K. Pouilly, J. Bouvier, E. Alecian +7
Context. Classical T Tauri stars (cTTs) are pre-main sequence stars surrounded by an accretion disk. They host a strong magnetic field, and both magnetospheric accretion and ejecti…
