Dynamo instabilities in plasmas with inhomogeneous chiral chemical potential

Jennifer Waltraud Schober

We study the dynamics of magnetic fields in chiral magnetohydrodynamics, which takes into account the effects of an additional electric current related to the chiral magnetic effect in high-energy plasmas. We perform direct numerical simulations, consideri ...

Gravitational tides and dwarf spheroidal galaxies

Pascale Jablonka, Yves Revaz, Matthew Luke Nichols

The effect of the local environment on the evolution of dwarf spheroidal galaxies is poorly understood. We have undertaken a suite of simulations to investigate the tidal impact of the Milky Way on the chemodynamical evolution of dwarf spheroidals that res ...

The CORALIE survey for southern extrasolar planets XVI. Discovery of a planetary system around HD 147018 and of two long period and massive planets orbiting HD 171238 and HD 204313

We report the detection of a double planetary system around HD 140718 as well as the discovery of two long period and massive planets orbiting HD 171238 and HD 204313. Those discoveries were made with the CORALIE Echelle spectrograph mounted on the 1.2-m E ...

Membership, binarity, and rotation of red dwarfs in the nearby open cluster Coma Berenices (Melotte 111)

Jean-Claude Mermilliod

Context. Although several attempts have been made to identify solar-type members on the main sequence of the nearby open cluster Coma Berenices (Mel 111), the population of the lower main sequence is still poorly known. ...
