In my first long trek outside the Bubble, I have noticed that some T Tauri type stars look just like main sequence stars. I don't notice they aren't until I try to scoop them and get nothing. Is there a scientific explanation for how they could look just like main sequence stars but not have a usable hydrogen atmosphere? Could they be changed somehow to set them more apart visually?
What I'm talking about: the reddish star in this image is not scoopable; the similar-looking (apart from the size difference) star in this image is.
