Relationship between X-ray and ultraviolet emission of flares from dMe stars observed by XMM-Newton
U. Mitra-Kraev, L. K. Harra, M. Guedel +6
We present simultaneous ultraviolet and X-ray observations of the dMe-type flaring stars AT Mic, AU Mic, EV Lac, UV Cet and YZ CMi obtained with the XMM-Newton observatory. During…
INTEGRAL/SPI Limits on Electron-Positron Annihilation Radiation from the Galactic Plane
B. J. Teegarden, K. Watanabe, P. Jean +24
The center of our Galaxy is a known strong source of electron-positron 511-keV annihilation radiation. Thus far, however, there have been no reliable detections of annihilation rad…
On the sizes of stellar X-ray coronae
J. -U. Ness, M. Güdel, J. H. M. M. Schmitt +2
Spatial information from stellar X-ray coronae can be inferred by use of scaling laws from the solar corona. This requires measurement of the physical parameters temperature and de…
Gamma-Ray Burst Polarization: Limits from RHESSI Measurements
C. Wigger, W. Hajdas, K. Arzner +2
Using the RHESSI satellite as a Compton polarimeter, a recent study claimed that the prompt emission of GRB021206 was almost fully linearly polarized. This was challenged by a subs…
