Spiral galaxy dynamics
Description
About the half of galaxies offers spiral shapes that remained unexplained for a long time. The problem of their origin remains unsolved but explanations are now given for such shapes to exist and to be maintained. Till now no contradiction with observation might infer the ruin of the theories built but the critical time occurs where new observations may confirm or cancel the various theoretical predictions
Abstract (French)
La moitie environ des galaxies presentent des formes spirales demeurees longtemps mysterieuses. Si le probleme de leur origine reste toujours ouvert, on sait maintenant comment une telle forme peut exister et se maintenir. Jusqu'a present, aucune contraelection avec l'observation n'est encore venue detruire le bel echafaudage des theoriciens. Mais le moment critique arrive ou, grace a de nouvelles observations, les diverses predictions de la theorie seront confirmees ou infirmeesAdditional details
