Sun too sluggish to act as a cosmic Concorde The sun is no cosmic Concorde. Our star is moving through a cloud of interstellar gas too slowly to create a "sonic boom" that would shield the solar system from some galactic cosmic rays. The finding could help determine whether the sun's previ...

Jupiter Twin Discovered Around Solar Twin An international group of astronomers has used the ESO 3.6-metre telescope to identify a planet just like Jupiter orbiting at the same distance from a Sun-like star, HIP 11915. According to current theories, the formation of Jupiter-mass planets plays a...

Title: Seismic modelling of the rotating, slowly pulsating B-type star HD 21071 Author: Wojciech Szewczuk, Jadwiga Daszyska-Daszkiewicz Interpretation of the oscillation spectrum of the slowly pulsating B-type star HD21071 is presented. We show that non-rotating models cannot account for...
