"Near-infrared Spectroscopy of Luminous Young Stellar Objects"

Miki Ishii (NAOJ, Japan)

While the evolutionary status of low-mass young stars is distinguished by the spectral energy distributions, such classification scheme has not been established for intermediate-mass young stellar objects. Near-infrared spectroscopy can be a powerful tool to study details about the YSO photospheres and the circumstellar environments, which cannot be probed by the SED alone. To examine the NIR spectral lines of the intermediate-mass YSOs, we observed the K band spectra of Herbig Ae/Be stars and Class I YSOs which are considered to be the precursors of Herbig Ae/Be stars. I'll present the results with a focus on the relation between the spectral lines and the SEDs, spectral types, ages. I'll also report preliminary results of the H band spectroscopy of Class I YSOs.


Seminars are also held at JAC, CFHT, and IfA.
