4 years ago Potential hierarchy paths:
- Stellar astronomy > Stellar types > Young stellar objects > Herbig Ae/Be stars
- Stellar astronomy > Stellar types > Young stellar objects > Herbig-Haro objects
- Stellar astronomy > Stellar types > Young stellar objects > Orion variable star > FU Orionis stars
- Stellar astronomy > Stellar types > Young stellar objects > Orion variable star > T Tauri stars > Classical T Tauri
- Stellar astronomy > Stellar types > Young stellar objects > Orion variable star > T Tauri stars > Weak-line T Tauri
- Stellar astronomy > Stellar types > Young stellar objects > Orion variable star > T Tauri stars
- Interstellar medium > Protostars > Young stellar objects > Herbig Ae/Be stars
- Interstellar medium > Protostars > Young stellar objects > Herbig-Haro objects
- Interstellar medium > Protostars > Young stellar objects > Orion variable star > FU Orionis stars
- Interstellar medium > Protostars > Young stellar objects > Orion variable star > T Tauri stars > Classical T Tauri
- Interstellar medium > Protostars > Young stellar objects > Orion variable star > T Tauri stars > Weak-line T Tauri
- Interstellar medium > Protostars > Young stellar objects > Orion variable star > T Tauri stars
I think "Orion variable stars" should also live somewhere under "Variable stars," but T Tauri stars and FU Orion stars don't live near each other in that hierarchy.
Name the new concept Orion variable star
Describe the concept https://en.wikipedia.org/wiki/Orion_variable
It could be a BT for both "FU Orionis stars" (http://astrothesaurus.org/uat/553) and "T Tauri stars" (http://astrothesaurus.org/uat/1681). Narrower term for both/either "Variable stars" or "Young Stellar Objects"
