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…
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…
New insights on the near-infrared veiling of young stars using CFHT/SPIRou data
A. P. Sousa, J. Bouvier, S. H. P. Alencar +10
Veiling is ubiquitous at different wavelength ranges in accreting stars. However, the origin of the veiling in the IR domain is not well understood. The accretion spot alone is not…
The GRAVITY Young Stellar Object survey. VII. The inner dusty disks of T Tauri stars
The GRAVITY Collaboration, K. Perraut, L. Labadie +55
These protoplanetary disks in T Tauri stars play a central role in star and planet formation. We spatially resolve at sub-au scales the innermost regions of a sample of T Tauri's d…
Interpretation of optical and IR light curves for transitional disk candidates in NGC 2264 using the extincted stellar radiation and the emission of optically thin dust inside the hole
Erick Nagel, Fernando Gutiérrez-Canales, Sebastián Morales-Gutiérrez +1
In the stellar forming region NGC 2264 there are objects catalogued as hosting a transitional disk according to spectrum modeling. Four members of this set have optical and infrare…
Star-disk interaction in the T Tauri star V2129 Oph: An evolving accretion-ejection structure
A. P. Sousa, J. Bouvier, S. H. P. Alencar +16
Classical T Tauri stars are young low-mass systems still accreting material from their disks. These systems are dynamic on timescales of hours to years. The observed variability ca…
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…
A study of accretion and disk diagnostics in the NGC 2264 cluster
Alana P. Sousa, Silvia H. P. Alencar, Luisa M. Rebull +3
Understanding disk dissipation is essential for studying how planets form. Disk gaps and holes, which almost correspond to dust-free regions, are inferred from infrared observation…
CSI 2264: Investigating rotation and its connection with disk accretion in the young open cluster NGC 2264
L. Venuti, J. Bouvier, A. M. Cody +7
The low spin rates measured for solar-type stars at an age of a few Myr (~10% of the break-up velocity) indicate that some mechanism of angular momentum regulation must be at play…
CSI 2264: Characterizing Young Stars in NGC 2264 with Stochastically Varying Light Curves
John Stauffer, Ann Marie Cody, Luisa Rebull +25
We provide CoRoT and Spitzer light curves, as well as broad-band multi-wavelength photometry and high resolution, multi- and single-epoch spectroscopy for 17 classical T Tauris in…
CSI 2264: Accretion process in classical T Tauri stars in the young cluster NGC 2264
Alana Sousa, Silvia Alencar, Jérôme Bouvier +12
Our goal is to relate the photometric and spectroscopic variability of classical T Tauri stars, of the star-forming cluster NGC 2264, to the physical processes acting in the stella…
CSI 2264: Probing the inner disks of AA Tau-like systems in NGC 2264
Pauline T. McGinnis, Silvia H. P. Alencar, Marcelo M. Guimaraes +20
The classical T Tauri star AA Tau presented photometric variability attributed to an inner disk warp, caused by the interaction between the inner disk and an inclined magnetosphere…
Mapping accretion and its variability in the young open cluster NGC 2264: a study based on u-band photometry
Laura Venuti, Jérôme Bouvier, Ettore Flaccomio +9
We aim at characterizing the accretion properties of several hundred members of the star-forming cluster NGC 2264 (3 Myr). We performed a deep u,g,r,i mapping and a simultaneous u+…
