Emission-line star?

  • Haian by Haian

    Usually emission-line stars have several spectral types form O to F and M type, and there are T Tauri stars with G type. Here we have G type, and they are luminous variable stars with low temperatures and they have strong emission lines,
    SIMBAD suggest strong emission line.
    and by using a VizieR photometry graph we find that the Lamda maximum is about 242 THZ== 1.23967 micrometer, so according to wien's low the star has low temperature (It's about 2400 K).
    -The T tauri emission-line stars are "Luminous variable stars", by compering between the images we have in Diskdetective with the other date images by using Aladin software we can see that the star HD 282695 is variable.

    • T tauri found in very young clusters and associated with interstellar gas clouds.
      My question is: What about the environment?. Because most of the stars surrounding HD 282695 are UVs. Dos it a member of a very young cluster?
