But it's also possible the obscuring clouds make it much more difficult to detect spectral lines from classical T Tauri stars.
The odd thing is that it's been remarkably difficult to find spectroscopic binaries among the classical T Tauri stars.
That could explain why some naked T tauri stars have companions but no circumstellar material, whereas classical T Tauri stars, with their accompanying dust clouds, appear rarely to have companions.
