XTgrid Live: Online spectral analyses with Tlusty models

Non-LTE model atmospheres are in the forefront of quantitative spectral analyses of early type stars. Yet, such models are barely used in large surveys or even for individual systems. The major reason for this is likely the extreme calculation requirements to construct such physically realistic models. To relieve this, we have developed a web-service for the spectral analysis program {\sc XTgrid}, which is meant to be a handy interface to {\sc Tlusty}. Having the procedure available from a web browser makes spectral analyses a routine.
