Absolute timing of the Crab Pulsar at optical wavelengths with STJs
T. Oosterbroek, J. H. J. de Bruijne, D. Martin +4
We have observed the Crab Pulsar in the optical with S-Cam, an instrument based on Superconducting Tunneling Junctions (STJs) with s time resolution. Our aim was to study the d…
High-Resolution spectroscopy of the low-mass X-ray binary EXO 0748-67
J. Cottam, S. M. Kahn, A. C. Brinkman +2
We present initial results from observations of the low-mass X-ray binary EXO 0748-67 with the Reflection Grating Spectrometer on board the XMM-Newton Observatory. The spectra exhi…
A Mission to Explore the Pioneer Anomaly
The Pioneer Explorer Collaboration, H. Dittus, S. G. Turyshev +37
The Pioneer 10 and 11 spacecraft yielded the most precise navigation in deep space to date. These spacecraft had exceptional acceleration sensitivity. However, analysis of their ra…
Fundamental Physics with the Laser Astrometric Test Of Relativity
LATOR Collaboration, S. G. Turyshev, H. Dittus +37
The Laser Astrometric Test Of Relativity (LATOR) is a joint European-U.S. Michelson-Morley-type experiment designed to test the pure tensor metric nature of gravitation - a fundame…
First Light Measurements with the XMM-Newton Reflection Grating Spectrometers: Evidence for an Inverse First Ionisation Potential Effect and Anomalous Ne A bundance in the Coronae of HR 1099
A. C. Brinkman, E. Behar, M. Guedel +15
The RS CVn binary system HR 1099 was extensively observed by the XMM-Newton observatory in February 2000 as its first-light target. A total of 570 ks of exposure time was accumulat…
Stellar Coronae with \textit{XMM-Newton} RGS. II. X-ray Variability
M. Audard, M. Guedel, A. J. den Boggende +16
First results from high-resolution coronal spectroscopy of flares with the Reflection Grating Spectrometers on board the \textit{XMM-Newton} satellite are reviewed. Rotational modu…
An XMM-Newton study of the X-ray binary MXB1659-298 and the discovery of narrow X-ray absorption lines
L. Sidoli, T. Oosterbroek, A. N. Parmar +2
We report the discovery of narrow X-ray absorption lines from the low-mass X-ray binary MXB1659-298 during an XMM-Newton observation in 2001 February. The 7.1 hr orbital cycle is c…
Stellar Coronae with \textit{XMM-Newton} RGS. I. Coronal Structure
M. Guedel, M. Audard, A. J. den Boggende +16
First results from high-resolution coronal spectroscopy with the {\it XMM-Newton} Reflection Grating Spectrometers (RGS) are reviewed. Five stellar systems (HR 1099, Capella, Procy…
Simultaneous Absolute Timing of the Crab Pulsar at Radio and Optical Wavelengths
T. Oosterbroek, I. Cognard, A. Golden +7
The Crab pulsar emits across a large part of the electromagnetic spectrum. Determining the time delay between the emission at different wavelengths will allow to better constrain t…
