Eta Carinae: the dissipating occulter is an extended structure
Theodore R. Gull, Henrik Hartman, Mairan Teodoro +10
Previous STIS long-slit observations of Eta Carinae identified numerous absorption features in both the stellar spectrum, and in the adjacent nebular spectra, along our line-of-sig…
Changes in the Na D Absorption Components of Carinae Provide Clues on the Location of the Dissipating Central Occulter
Connor S. Pickett, Noel D. Richardson, Theodore Gull +9
The Na D absorption doublet in the spectrum of Carinae is complex, with multiple absorption features associated with the Great Eruption (1840s), the Lesser Eruption (1890s), an…
Eta Carinae: an evolving view of the central binary, its interacting winds and its foreground ejecta
Theodore R. Gull, D. John Hillier, Henrik Hartman +13
FUV spectra of Eta Car, recorded across two decades with HST/STIS, document multiple changes in resonant lines caused by dissipating extinction in our line of sight. The FUV flux h…
Stellar Population Astrophysics (SPA) with the TNG: Identification of a Sulphur line at lambda(air) = 1063.600nm in GIANO-B stellar spectra
N. Ryde, H. Hartman, E. Oliva +6
Context. In the advent of new infrared, high-resolution spectrometers, accurate and precise atomic data in the infrared is urgently needed. Identifications, wavelengths, strengths,…
4MOST: Project overview and information for the First Call for Proposals
R. S. de Jong, O. Agertz, A. Agudo Berbel +335
We introduce the 4-metre Multi-Object Spectroscopic Telescope (4MOST), a new high-multiplex, wide-field spectroscopic survey facility under development for the four-metre-class Vis…
Benchmarking Atomic Data for Astrophysics: Be-like Ions between B II and Ne VII
Kai Wang, Zhan Bin Chen, Chun Yu Zhang +6
Large-scale self-consistent multiconfiguration Dirac--Hartree--Fock and relativistic configuration interaction calculations are reported for the levels in Be-like ions f…
