Title: Physical Parameters of the Visually Close Binary Systems Hip70973 and Hip72479 Authors: Mashhoor Al-Wardat Atmospheric modelling of the components of the visually close binary systems Hip70973 and Hip72479 was used to estimate the individual physical parameters of their components....
ZX Spectrum's chief designers reunited 30 years on The ZX Spectrum is 30 years old. The successor to Sir Clive Sinclair's ZX81 - at the time the world's best selling consumer computer - it introduced colour "high resolution" graphics and sound. It also offered an extended version of Sin...
Title: Investigating the reflection contribution to the X-ray emission of Ton S180 Authors: E. Nardini, A.C. Fabian, D.J. Walton There is now growing evidence that the soft X-ray excess is almost ubiquitous among unobscured active galaxies. In spite of the various interpretations that have bee...
Half-a-billion years ago, as an explosion of life was starting to produce diverse new forms, the Antrim Plateau Volcanics of northern Australia began spewing massive amounts of lava.
Before it was over, lava floods had buried almost a fifth of Australia's area today.
The newly identified K...
Intel's Ivy Bridge chips launch using '3D transistors' Intel is launching its Ivy Bridge family of processors - the first to feature what it describes as a "3D transistor". The American firm says the innovation allows it to offer more computational power while using less energy. The in...
Micromachined Propulsion systems for very small satellites Electric propulsion for spacecraft provides thrust by emitting electrically-charged particles extremely high speeds. Such thrusters do not burn fuel, they eject it. Since the speed of the outgoing particles are much higher for ele...
