η Carinae: linelist for the emission spectrum of the Weigelt blobs in the 1700 to 10400Å wavelength region. Zethson T., Johansson S., Hartman H., Gull T.R. <Astron. Astrophys. 540, A133 (2012)> =2012A&A...540A.133Z

The aim of this work is to characterize the behavior of these luminous, dense gas blobs in response to the broad high-state and the short low-state of η Carinae during its 5.54-year spectroscopic period. Description: The spectra were recorded in a low state (March 1998) and an early high state (February 1999) with the Hubble Space Telescope/Space Telescope Imaging Spectrograph (HST/STIS) from 1640 to 10400Å using the 52"x0.1" aperture centered on Eta Carinae at position angle, PA=332 degrees. Extractions of the reduced spectrum including both Weigelt B and D, 0.28" in length along the slit, were used to identify the narrow, nebular emission lines, measure their wavelengths and estimate their fluxes. A linelist of 2500 lines is presented for the high and low states of the combined Weigelt blobs B and D.

Note (1): The identifications for the region 2424-2706Å are improved using the line list by Nielsen et al. (2007, Cat. J/ApJS/168/289) based on high resolution HST/STIS spectra. The identifications and laboratory wavelengths are retrieved from the Kurucz database (Kurucz, 2001, http://cfaku5.harvard.edu/atoms.html). The laboratory wavelengths for parity forbidden lines are Ritz wavelengths derived from energy levels in the NIST Atomic Spectra Database (2006). Note (2): Comments used as follows: Not in 98 = The feature is not present in the 1998 observation Not in 99 = The feature is not present in the 1999 observation Lyα = Primary H Lyα pumped fluorescence transition Lyα sec. = Secondary H Lyα pumped fluorescence transition 4p-4s = A 4p-4s transition, discussed in section 5.5 Si III] = Fluorescence line pumped by Si III (Hartman & Johansson, 2000A&A...359..627H) He II = Fluorescence line pumped by He II (Hartman & Johansson, 2000A&A...359..627H) N IV] = Fluorescence line pumped by N IV] (Hartman & Johansson, 2000A&A...359..627H) rd_sh = red shoulder due to extended stellar wind is noticeable out to +400km/s bl_sh = blue shoulder due to extended stellar wind is noticeable out to -400km/s ? = the feature is weak and may not be a true emission line ?id = The identification is regarded as uncertain ?Eu = the upper level has an excitation energy >10eV, and the excitation mechanism is questionable ?wl = Plausible identification, but the radial velocity differs from the mean, -45km/s, by >15km/s
