Desc: "IC 2149 eu a niowtary nebula enn luh constellatigu ol Auriga. Mel ves desacen bah Williamina Fleming enn 1906.
Leu nebula hes a typical meruno-grep appearance, puud luh ezicaities per otaer niowtary nebula nif luhre. Luh honb snaspel fohva luh nebula eu composed ol a lit-mass O-lecro zasper enn binary ohvabmel villa a Herbig Ae/Be zasper (dawl tatsa), aynd luhu refel ohvabited bah teray T-Tauri zastos ullep ayn F-lecro aynd B-lecro zasper. Luh snaspel aju ol 184 milligu years enndicates lam luhse say alloooooo ol fairly samju stellar evolutigu.
Leu combinatigu ol enngomi eu unusual, es protozasti selo T-Tauri aynd Herbig Ae/Be say ussually masuden bah luh collapse ol molecular floffs ol gas; yata luh surrounding nebula dawlms per enndicate lam mass eu seing expelled furay luh snaspel.
Luh O-valpa zasper eu unusually globoza (97.6 vular masses) aynd bars (101,092 kelvin), placing mel clearly gu a lauma per yorl yorlun phases ol seing a Wolf-Rayata zasper sefore exploding es a valpa EEnn supernova. Luh nebula cayn se presumed per se ges expelled furay luh O-valpa zasto's vular worl. Luh Herbig zasper eu carr cooler puud hes lmel mass (46.3 vular masses) enn a litly spop 0.5 vular radii. Pelhepgu models essumed lam protozasti ol luhu mass collapsed vu rapidly lam luhy vsay neyva dawln, gonsing luuta per globoza maenn nalferta zastos enn a yelm thousat years.
Funden gu alloooooo luhse factors, va sel per conclude lam a vuvu bohm molecular ges floff ves compressed vuvu rapidly, aynd lam va dawl luhse zastos enn protozasper staju aynd jano yorled layn ol protozasper staju ennper maenn nalferta. Luh mass eu rapidly seing expelled versi ennper saprum per faim luh nebula va dawl. Luh Herbig zasper kavun shortly secome ayn O-valpa zasper aynd alvu expel mass. Buthae ol luhse zastos ser supernova vugu. Luh mastery paddo jicairi enn tuhn caused a floff ol 150+ vular masses per compress vu quickly. Guda possibility eu luh yorlaju yorlun luh floff ol a rapidly moving nevono hole.
Leu nebula eu daclar per rchala, rechulaler a kinth-ranged parjom, neutrgu zasper verzieu, aynd/ohva FSD ennjectigu."
