Observation of enhanced X-ray emission from the CTTS AA Tau during a transit of an accretion funnel
Nicolas Grosso, Jérôme Bouvier, Thierry Montmerle +3
AA Tau was observed for about 5h per XMM orbit (2 days) over 8 successive orbits, which covers two optical eclipse periods (8.2 days). The XMM optical/UV monitor simultaneously pro…
SIM PlanetQuest Key Project Precursor Observations to Detect Gas Giant Planets Around Young Stars
Angelle Tanner, Charles Beichman, Rachel Akeson +10
We present a review of precursor observing programs for the SIM PlanetQuest Key project devoted to detecting Jupiter mass planets around young stars. In order to ensure that the st…
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…
Results of the ROTOR-program. I. The long-term photometric variability of classical T Tauri stars
K. N. Grankin, S. Yu. Melnikov, J. Bouvier +2
We present a unique, homogeneous database of photometric measurements for Classical T Tauri stars extending up to 20 years. The database contains more than 21,000 UBVR observations…
The Stellar Composition of the Star Formation Region CMa R1 -- III. A new outburst of the Be star component in Z CMa
M. E. van den Ancker, P. F. C. Blondel, H. R. E. Tjin A Djie +5
We report on a recent event in which, after more than a decade of slowly fading, the visual brightness of the massive young binary Z CMa suddenly started to rise by about 1 magnitu…
The weak-line T Tauri star V410Tau I. A multi-wavelength study of variability
B. Stelzer, M. Fernandez, V. M. Costa +10
We present the results of an intensive coordinated monitoring campaign in the optical and X-ray wavelength ranges of the low-mass, pre-main sequence star V410Tau carried out with t…
