NEAR-IR Spectroscopy of Young Stars in the Braid Nebula Star Formation Region in Cygnus Ob7
Colin Aspin, Tracy L. Beck, Tae-Soo Pyo +8
We present 1.4 to 2.5 um integral field spectroscopy of 16 stars in the Braid Nebula star formation region in Cygnus OB7. These data forms one aspect of a large-scale multi-wavelen…
Magnetospheric accretion-ejection processes in the classical T Tauri star AA
J. Bouvier, S. H. P. Alencar, T. Boutelier +8
From a long time series of high resolution (R=115,000) HARPS spectra and simultaneous broad-band photometry, we report new evidence for magnetospheric accretion as well as ejection…
An Outbursting Protostar of the FU~Orionis type in the Cygnus OB7 Molecular Cloud
T. A. Movsessian, T. Khanzadyan, C. Aspin +5
Context: To follow the early evolution of stars we need to understand how young stars accrete and eject mass. It is generally assumed that the FU Orionis phenomenon is related to t…
Eclipses by circumstellar material in the T Tauri star AA Tau. II. Evidence for non-stationary magnetospheric accretion
J. Bouvier, K. N. Grankin, S. H. P. Alencar +12
We report the results of a synoptic study of the photometric and spectroscopic variability of the classical T Tauri star AA Tau on timescales ranging from a few hours to several we…
