... The unexpected discovery of Jupiter-size planets very close to their parent stars (two examples of which are 51 Peg and Boo) creates a challenge for theories of planetary formation and structure. ... Direct observation of such extra-solar planets with an infrared interferometer is a difficult task because of the very high dynamic range required (typically 3?104 to 3?105), but not impossible if a very careful spatial filtering and calibration is imposed upon the recombined beams. ...

. To remove a directory that is a symbolic link that points to another directory use the command: rm directory_name . Notice that the directory does not need to be empty and you do not have to use the rmdir command. You are not really removing a directory, just a named symbolic link that points to the "real" directory.

... This paper describes the main algorithms used by the Einstein Level One processing to create the exposure masks and the background maps for Einstein IPC images, and how these algorithms were recreated in the IRAF environment. Our goal was to recreate the algorithms used by the Level One Processing to create exposure masks and background maps for Einstein Image Proportional Counter (IPC) data (cf. sections 2.5 and 2.7 of Harnden et al. ...

... Aurora from Space . ... Magnetic Storms . ... The "ring of fire" seen by satellite cameras around the polar caps (picture below) is probably created by electrons leaking from the tail's plasma sheet, whose magnetic field lines form a somewhat imperfect trap. ... One possible explanation involves the close association between auroral arcs and electric currents which flow along field lines between the ionosphere and distant space ( Birkeland currents ). ... Why no aurora at the magnetic poles? ...
