Abstract
For this project we present a spectro-astrometric study of the Hα emission from T Cha, a young stellar object with a transitional disk. The aim is to explore the possibility of detecting a substellar companion using spectro-astrometry. While no spectro-astrometric signal was found in the Hα line it is planned that the next step will be to combine the spectro-astrometric results with estimates of the mass accretion rate for T Cha to put an upper limit on the mass accretion rate onto any companion.
