X-ray emission of brown dwarfs: Towards constraining the dependence on age, luminosity, and temperature
B. Stelzer, G. Micela, E. Flaccomio +7
Three brown dwarfs in different evolutionary stages have been observed with the Chandra X-ray Observatory. Combining the new observations with previous studies presented in the lit…
Stellar Activity on the Young Suns of Orion: COUP Observations of K5-7 Pre-Main Sequence Stars
S. J. Wolk, E. Flaccomio, G. Micela +4
In January 2003, the Chandra Orion Ultradeep Project (COUP) detected about 1400 young stars during a 13.2 day observation of the Orion Nebula Cluster (ONC). This paper studies a we…
The Origin of T Tauri X-ray Emission: New Insights from the Chandra Orion Ultradeep Project
Thomas Preibisch, Yong -Cheol Kim, Fabio Favata +8
We use the data of the Chandra Orion Ultradeep Project (COUP) to study the nearly 600 X-ray sources that can be reliably identified with optically well characterized T Tauri stars…
Rotational modulation of X-ray emission in Orion Nebula young stars
E. Flaccomio, G. Micela, S. Sciortino +5
We investigate the spatial distribution of X-ray emitting plasma in a sample of young Orion Nebula Cluster stars by modulation of their X-ray light-curves due to stellar rotation.…
Bright X-ray flares in Orion young stars from COUP: evidence for star-disk magnetic fields?
F. Favata, E. Flaccomio, F. Reale +5
We have analyzed a number of intense X-ray flares observed in the Chandra Orion Ultradeep Project (COUP), a 13 days observation of the Orion Nebula Cluster (ONC). Analysis of the f…
X-ray emission from young brown dwarfs in the Orion Nebula Cluster
Thomas Preibisch, Mark J. McCaughrean, Nicolas Grosso +8
We use the sensitive X-ray data from the Chandra Orion Ultradeep Project (COUP) to study the X-ray properties of 34 spectroscopically-identified brown dwarfs with near-infrared spe…
