Abstract
Herbig Ae/Be stars are Pre-Main Sequence objects of intermediate mass. It is expected that within their mass range, the transition between the magnetically controlled accretion process for low mass stars and the still unknown process for higher mass stars occurs. We have derived luminosities for 107 of these objects using TGAS parallaxes, thus allowing to place them in the HR diagram. The number of Herbig Ae/Be stars in the HR diagram with directly determined distances has increased by more than a factor of 5 with this study. We analysed the infrared excesses of the 107 Herbig Ae/Be stars and present an evolutionary analysis to be done in the future.
