| Abstract: |
η Carinae was observed by FUSE through the LWRS (30″×30″) and HIRS (1.25″×20″) apertures in March and April 2004. There are significant differences between the two spectra. About half of the LWRS flux appears to be due to two B-type stars near the edge of the LWRS aperture, 14″ from η Car. The HIRS spectrum (LiF1 channel) therefore reveals the intrinsic FUV spectrum of η Car without this stellar contamination. The HIRS spectrum contains strong interstellar H2 having high rotational excitation (up to J = 8). Most of the atomic species with prominent ISM features (C II, Fe II, Ar I, P II, etc) also have strong blue-shifted absorption to v ∼ −580 km/s that is associated with expanding debris from the 1840 eruption. |
