Twenty-Five Years of Accretion onto the Classical T Tauri Star TW Hya

Gregory J. Herczeg, Yuguang Chen, Jean-Francois Donati +39

Accretion plays a central role in the physics that governs the evolution and dispersal of protoplanetary disks. The primary goal of this paper is to analyze the stability over time…

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…

The magnetic field and multiple planets of the young dwarf AU~Mic

J. -F. Donati, P. I. Cristofari, B. Finociety +25

In this paper we present an analysis of near-infrared spectropolarimetric and velocimetric data of the young M dwarf AU Mic, collected with SPIRou at the Canada-France-Hawaii teles…

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…
