Abstract
Improved and additional data for the T Tauri-like objects, with more realistic assumptions concerning extinction, allow us to calculate new values for the luminosities of eleven stars. Both the spectroscopic and photometric luminosities are considered; in several cases, they are found to disagree. These discrepancies may be resolved if the extinction affecting these stars is peculiar, with a large value of the ratio of total to selective absorption. The recalculated values of the spectroscopic luminosities then give a good representation of the luminosities of the objects. The stars are located in the Hertzsprung-Russell diagram; their positions are consistent with previous investigations and have been used to estimate the objects' masses and ages.
