Abstract
Eta Carinae is a super-massive, super-luminous star. It is surrounded by a bipolar nebula, the "Homunculus", and several blobs of ejected gas which are the source of a complex emission-line spectrum. This thesis presents results from spectroscopic investigations of the star and its surroundings, performed with the Space Telescope Imaging Spectrograph (STIS) and the Goddard High Resolution Spectrograph (GHRS) onboard the Hubble Space Telescope (HST). The age of the equatorial disk in the Homunculus has been studied by measurements of radial velocities of emission lines. Fluorescence processes in Fe II, Fe III, and Cr II are discussed, and the discovery of an ejected filament producing Sr II and [Sr II] emission is reported. Also, a list of 2000 emission line identifications is presented and discussed. The chemically peculiar star Chi Lupi was the target of the "Pathfinder Project", a mapping of the UV spectrum of the star using the GHRS. An investigation of the abundance and isotopic composition of boron in Chi Lupi is presented. The launch of space telescopes has put greater demands on the quality of atomic data needed for the analyses of the observed spectra. This thesis presents laboratory measurements of wavelengths and transitions isotope shifts in the B~II spectrum.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
