... Judged by their instrumental profiles, spectrometers fall into two basic classes---Lorentzian and Gaussian---with many other line profile functions (sinc functions, Voigt functions, Airy functions, etc.) falling into one of these two categories in some limit. We demonstrate that the Rayleigh, Sparrow, and Houston resolution criteria are of limited use compared to the ``equivalent width'' of the line profile. ... Rayleigh criterion. ... All of these functions have continuous higher derivatives. ...

. NASA's Kepler spacecraft, launched in March 2009, is designed to discover Earth-like planets orbiting other stars. In the process it is capturing large quantities of data on the target stars which is used not only to search for planets but also to study stars in general. The results from NASA's Kepler spacecraft provide us with new information on a number of specific phenomena related to our fundamental knowledge of stars, their internal properties and evolution in time.

Raquel Salmeron The mechanism(s) responsible for generating the angular momentum transport required for star/planet formation remain poorly understood. ... In recent times it has been realised that the answer may lie in the complex interaction of gas and magnetic fields present in the flattened disc of material that surrounds the star in formation (e.g., Balbus Hawley 1998) . ...

... Compact Binaries . ... Unlike the Sun, most stars in our Galaxy orbit another star: these systems are called binary stars. Generally it takes many years for the two stars to orbit around each other. ... These binaries are interesting for many reasons. One is that they are predicted to emit lots of gravitational waves. ... Over time as gravitational waves are emitted, the time taken for the two stars to orbit one another changes by a small but measurable amount. ...
