Aims. Substellar objects have extremely long life-spans. The cos mological consequence for older objects are low abundances of heavy elements, which results in a wide distribution of objects ov er metallicity, hence over age. Within their cool atmospher e, dust clouds become a dominant feature, a ffecting the opacity and the remaining gas phase abundance of h eavy elements. We investigate the influence of the stellar metallicity on the dust formation in subs tellar atmospheres and on the dust… CONTINUE READING
