. Shell procedures may use the trap command to catch or ignore Unix operating system signals . The form of the trap command is: trap ' command-list ' signal-list . Several traps may be in effect at the same time. If multiple signals are received simultaneously, they are serviced in ascending order. To check what traps are currently set use the trap command. For example: trap . Most common signals to be caught . Handling command lists . Examples .

We have obtained simultaneous high resolution H alpha and Na I D spectra of five dwarf M stars that span a wide range in chromospheric activity level. ... However, the H alpha line systematically indicates a value for the mass loading at the onset of the Transition Region and the location of T_min that is 0.4 dex lower in column mass density than that indicated by NaI D. Therefore, the profile of both lines cannot be simultaneously well fit for all but one of our stars. ...

... An artist's concept of a terrestrial planet orbiting the star Alpha Centauri B. Image courtesy of Mark Fisher . Does Alpha Centauri Have Planets? ... UCSC graduate student Javiera Guedes used computer simulations of planet formation to show that terrestrial planets are likely to have formed around the star Alpha Centauri B and to be orbiting in the ?habitable zone? where liquid water can exist on the planet?s surface. The researchers then showed that such planets could be observed. ...

... The Workshop is dedicated to QCD Phase Transitions and observational signals of these Transitions related to formation of compact astrophysical objects. The aim of this workshop is to bring together researchers working on the problems of the behavior and observability of matter under critical conditions achievable in such astrophysical objects as 'strange' or 'hybrid' stars and in laboratories at heavy-ion collisions to discuss fundamental issues and recent developments. ...

... Aims: Today, large ground-based instruments, like VISIR on the VLT, providing diffraction-limited (about 0.3 arcsec) images in the mid-infrared where strong PAH features appear enable us to see the flaring structure of the disks around Herbig Ae stars. Although great progress has been made in modelling the disk with radiative transfer models able to reproduce the spectral energy distribution (SED) of Herbig Ae stars, the constraints brought by images have not been yet fully exploited. ...
