POLAR, a compact detector for Gamma Ray Bursts photon polarization measurements
N. Produit, F. Barao, S. Deluit +7
The design and the simulated performances of a compact detector dedicated to the measurement of GRB photon polarization is presented. Such a detector would permit to answer the que…
Statistical Properties of Dissipative MHD Accelerators
Kaspar Arzner, Loukas Vlahos, Bernard Knaepen +1
We use exact orbit integration to investigate particle acceleration in a Gauss field proxy of magnetohydrodynamic (MHD) turbulence. Regions where the electric current exceeds a cri…
Attacking the X-ray emission properties of young stars with the Sword of Orion
K. R. Briggs, M. Guedel, M. Audard +1
We present a survey of X-ray emission from young stars in the Sword of Orion star-formation region using XMM-Newton's EPIC detectors. We find over 850 X-ray sources, of which more…
A Multiwavelength Study of RZ Cassiopeiae: The XMM-Newton/VLA Campaign
Marc Audard, Julius R. Donisan, Manuel Guedel
XMM-Newton and the VLA simultaneously observed the eclipsing Algol-type binary RZ Cassiopeiae in August 2003. The secondary eclipse (K3 IV companion behind the A3 V primary) was pl…
High-Energy Processes in Young Stars: Chandra X-ray Spectroscopy of HDE 283572, RY Tau, and LkCa 21
Marc Audard, Stephen L. Skinner, Kester W. Smith +2
Weak-lined T Tauri stars (WTTS) represent the important stage of stellar evolution between the accretion phase and the zero-age main sequence. At this stage, the star decouples fro…
Coronae of Cool Stars
M. Audard, S. A. Drake, M. Güdel +6
We present preliminary results of grating observations of YY Mensae and V824 Arae by Chandra and XMM-Newton. Spectral features are presented in the context of the emission measure…
