Discovery of the X-ray Burster Sax J1752.3–3138
During a 50 ks monitoring observation of the Galactic bulge performed in September 1999 by the Wide Field Cameras on board the BeppoSAX satellite, an X-ray burst was detected from a sky position ∼ 3 • off the Galactic centre. No previously known X-ray sources are located within the position error circle of the observed burst. The new burster, SAX J1752.3−3138, did not show any persistent emissi...
متن کاملThe X-ray Spectrum of Sax J1808.4-3658
We report on the X-ray spectrum of the 401 Hz X-ray pulsar and type I burst source SAX J1808.4-3658 during its 1998 April/May hard outburst. The observations were made with RXTE over a period of three weeks. The spectrum is well-described by a power law with photon index 1.86 ± 0.01 that is exponentially cut off at high energies. Excess soft emission above the power law is present as well as a ...
متن کاملX-ray Astronomy of Stellar Coronae ⋆
X-ray emission from stars in the cool half of the Hertzsprung-Russell diagram is generally attributed to the presence of a magnetic corona that contains plasma at temperatures exceeding 1 million K. Coronae are ubiquitous among these stars, yet many fundamental mechanisms operating in their magnetic fields still elude an interpretation through a detailed physical description. Stellar X-ray astr...
متن کاملX-ray Interferometry: Ultra High Resolution Astronomy
X-rays have tremendous potential for imaging at the highest angular resolution. The high surface brightness of many xray sources will reveal angular scales heretofore thought unreachable. The short wavelengths make instrumentation compact and baselines short. We discuss how practical x-ray interferometers can be built for astronomy using existing technology. We describe the Maxim Pathfinder and...
