Scientific paper

We present spectra of the Class I embedded source GSS 30 IRS 1 covering four pure rotational H2 transitions: J=3-1 (17.0 um), J=4-2 (12.3 um), J=6-4 (8.0 um), and J=11-9 (4.7 um). The observations at 8 um and longer were taken with TEXES, a high resolution, mid-IR spectrograph, during its July Science Verification run at Gemini North. The 4.7 um observations come from NIRSPEC on Keck II. Fitting to the observations, we are able to investigate the temperature and mass of warm, emitting gas. We will discuss our results in the context of CO emission from the same object presented in Pontoppidan et al (2002).
