The dance of dust: Investigating young stellar object dipper variability
A. Empey, R. Garcia Lopez, A. Natta +4
The dipper subclass of YSOs are characterised by frequent dips in their light curves. Irregular dippers do not show periodic signatures and have dips accounting for significant pro…
A Multi-wavelength, Multi-epoch Monitoring Campaign of Accretion Variability in T Tauri Stars from the ODYSSEUS Survey. III. Optical Spectra
John Wendeborn, Catherine C. Espaillat, Thanawuth Thanathibodee +20
Classical T Tauri Stars (CTTSs) are highly variable stars that possess gas- and dust-rich disks from which planets form. Much of their variability is driven by mass accretion from…
Correlation between the optical veiling and accretion properties: A case study of the classical T Tauri star DK Tau
M. Nelissen, A. Natta, P. McGinnis +3
Classical T Tauri stars (cTTs) accrete from their circumstellar disk. The material falls onto the stellar surface, producing an accretion shock, which generates veiling in a star's…
Misalignment of the outer disk of DK Tau and a first look at its magnetic field using spectropolarimetry
M. Nelissen, P. McGinnis, C. P. Folsom +7
Misalignments between a forming star's rotation axis and its outer disk axis, although not predicted by standard theories of stellar formation, have been observed in several classi…
Accretion variability in RU Lup
Camille Stock, Pauline McGinnis, Alessio Caratti o Garatti +2
The process of accretion in classical T Tauri stars (CTTSs) has been observed to vary on different timescales. Studying this variability is vital to understanding a star's evolutio…
PENELLOPE: the ESO data legacy program to complement the Hubble UV Legacy Library of Young Stars (ULLYSES) I. Survey presentation and accretion properties of Orion OB1 and -Orionis
C. F. Manara, A. Frasca, L. Venuti +69
The evolution of young stars and disks is driven by the interplay of several processes, notably accretion and ejection of material. Critical to correctly describe the conditions of…
Investigating episodic accretion in a very low-mass young stellar object
Camille Stock, Alessio Caratti o Garatti, Pauline McGinnis +4
Very low-mass Class I protostars have been investigated very little thus far. Variability of these young stellar objects (YSOs) and whether or not they are capable of strong episod…
The magnetic obliquity of accreting T Tauri stars
Pauline McGinnis, Jérôme Bouvier, Florian Gallet
Classical T Tauri stars (CTTS) accrete material from their discs through their magnetospheres. The geometry of the accretion flow strongly depends on the magnetic obliquity, i.e.,…
Ejection processes in the young open cluster NGC 2264. A study of the [OI]λ6300 emission line
Pauline McGinnis, Catherine Dougados, Silvia H. P. Alencar +2
We search for correlations between the [OI]6300 line, a well-known tracer of jets and winds in young stars, and stellar/disk/accretion properties in the young cluster NGC 2264, aim…
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…
CSI 2264: Characterizing Young Stars in NGC 2264 with Short-Duration, Periodic Flux Dips in their Light Curves
John Stauffer, Ann Marie Cody, Pauline McGinnis +27
We identify nine young stellar objects (YSOs) in the NGC 2264 star-forming region with optical {\em CoRoT} light curves exhibiting short-duration, shallow, periodic flux dips. All…
Accretion dynamics and disk evolution in NGC 2264: a study based on the Corot photometric observations
S. H. P. Alencar, P. S. Teixeira, M. M. Guimaraes +6
The young cluster NGC 2264 was observed with the Corot satellite for 23 days uninterruptedly in March 2008 with unprecedent photometric accuracy. We present here the first results…
