LetGbe a simple algebraic group over an algebraically closed fieldk; assume that Charkis zero or good forG. Letbe the variety of Borel subgroups ofGand letbe nilpotent. There is a natural action of the centralizerCG(e) ofeinGon the Springer fibreassociated toe. In this paper we consider the case, whereelies in the subregular nilpotent orbit; in this caseis a Dynkin curve. We give a complete description of theCG(e)-orbits in. In particular, we classify the irreducible components ofon whichCG(e) acts with finitely many orbits. In an application we obtain a classification of all subregular orbital varieties admitting a finite number ofB-orbits forBa fixed Borel subgroup ofG.
