A symplectic approach to gravitational instability

J. Perez, M. Lachieze-Rey

We present a global approach of non-dissipative physics. Based on symplectic mechanics this technique allows us to obtain the solution of a very large class of problems in terms of…

Stability of spherical stellar systems I : Analytical results

J. Perez, J-J Aly

The so-called ``symplectic method'' is used for studying the linear stability of a self-gravitating collisionless stellar system, in which the particles are also submitted to an ex…

SEARCH FOR VERY LOW MASS OBJECTS IN THE GALACTIC HALO

EROS collaboration, E. Aubourg, P. Bareyre +26

We present results from a search for gravitational microlensing of stars in the Large Magellanic Cloud by low mass objects in the Galactic Halo. The search uses the CCD light curve…

The Parker-Shearing instability in azimuthaly magnetized discs

Thierry Foglizzo, Michel Tagger

We describe the effects of both magnetic buoyancy and differential rotation on a disc of isothermal gas embedded in a purely azimuthal magnetic field, in order to study the evoluti…

Variable polarisation and luminosity for microlensing of extended stellar sources

J. F. L. Simmons, A. M. Newsam, J. P. Willis

Microlensing of extended stellar sources in the LMC and Galaxy by low mass lenses can produce variable polarisation. The characteristics of the polarisation and flux profiles can p…
