"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,
