3D simulations of magnetospheric accretion in T Tauri stars: I. Disk truncation, stellar torques, and application to observations
George Pantolmos, Claudio Zanni, Jérôme Bouvier
Young stars accrete material from their circumstellar disk through their magnetosphere and undergo contraction; these two processes impact their rotational evolution. We investigat…
Magnetic field measurements in a sample of Class I and flat-spectrum protostars observed with SPIRou
L. Drouglazet, E. Alecian, A. Sousa +27
Magnetic fields play a crucial role throughout stellar evolution, regulating angular momentum, channelling accretion, and launching jets and outflows. While the magnetic properties…
The interplay between disk wind and magnetospheric accretion mechanisms in the innermost environment of RU Lup
J. A. Wojtczak, B. Tessore, L. Labadie +10
Aims: Our aim is to build upon the analysis presented in our previous work by attempting to match the observational data obtained with VLTI GRAVITY for RU Lup in 2021 with an expan…
Long period modulation of the classical T Tauri star CI Tau: evidence for an eccentric close-in massive planet at 0.17 au
R. Manick, A. P. Sousa, J. Bouvier +13
Detecting planets within protoplanetary disks around young stars is essential for understanding planet formation and evolution. However, planet detection using the radial velocity…
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…
The GRAVITY young stellar object survey -- XI. Probing the inner disk and magnetospheric accretion region of CI Tau
GRAVITY Collaboration, A. Soulain, K. Perraut +6
Aims: We aim at spatially and spectrally resolving the innermost scale of the young stellar object CI Tau to constrain the inner disk properties and better understand the magnetosp…
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…
Spectroscopic and interferometric signatures of magnetospheric accretion in young stars
B. Tessore, A. Soulain, G. Pantolmos +3
Methods. We use the code MCFOST to solve the non-LTE problem of line formation in non-axisymmetric accreting magnetospheres. We compute the Brγ line profile originating from accret…
Magnetic braking of accreting T Tauri stars: Effects of mass accretion rate, rotation, and dipolar field strength
Lewis G. Ireland, Claudio Zanni, Sean P. Matt +1
The rotational evolution of accreting pre-main-sequence stars is influenced by its magnetic interaction with its surrounding circumstellar disk. Using the PLUTO code, we perform 2.…
Magnetic torques on T Tauri stars: accreting vs. non-accreting systems
G. Pantolmos, C. Zanni, J. Bouvier
Classical T Tauri stars (CTTs) magnetically interact with their surrounding disks, a process that is thought to regulate their rotational evolution. In this work, we compute torque…
Magnetic braking of Sun-like and low-mass stars: Dependence on coronal temperature
George Pantolmos, Sean P. Matt
Sun-like and low-mass stars possess high temperature coronae and lose mass in the form of stellar winds, driven by thermal pressure and complex magnetohydrodynamic processes. These…
