Title: Energetics of nearby stellar bow shocks Authors: Paula Benaglia The latest survey of stellar bow shocks (Peri et al. 2012) lists 28 candidates detected at IR wavelengths, associated with massive, early-type stars up to 3 kpc, along with the geometrical parameters of the structures found....
Title: Revealing Gamma-Ray Binaries Authors: I. F. Mirabel Recent ground based and space telescopes that detect high energy photons from a few up to hundreds of gigaelectron volts (GeV) have opened a new window on the universe. However, because of the relatively poor angular resolution of these t...
Title: Attempts to reproduce the rotation profile of the red giant KIC 7341231 observed by Kepler Authors: T. Ceillier, P. Eggenberger, R. A. García, S. Mathis Thanks to the asteroseimic study of the red giant star KIC 7341231 observed by Kepler, it has been possible to infer its radial differentia...

The maths that made Voyager possible Nasa's Voyager spacecraft have enthralled everyone with their exploits at the edge of the Solar System, but their launch in 1977 was only possible because of some clever maths and the persistence of a PhD student, Michael Minovitch, who worked out how to slingsh...
