HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT

Laura Magrini, Thomas Bensby, Sofia Randich +174

This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…

The nucleosynthesis of Ba in the Early Universe. Constraints from elemental abundances and isotopic ratios

Riano E. Giribaldi, Marco Palla, Laura Magrini +6

The [Ba/Eu] abundance ratio is commonly adopted as a tracer of the relative contributions of the slow (s) and rapid (r) neutron-capture processes. However, at [Fe/H] < -2 dex, Ba c…

Wavelengths and Energy Levels of Neutral Manganese (Mn I) Determined Using High-Resolution Fourier Transform and Grating Spectroscopy

Christian P. Clear, Gillian Nave, Richard Blackwell-Whitehead +3

An extensive analysis of the spectrum of neutral manganese has been performed using spectra of manganese-neon and manganese-argon hollow cathode discharges measured using high reso…

Discovery of an icy and nitrogen-rich extrasolar planetesimal

Snehalata Sahu, Boris T. Gänsicke, Jamie T. Williams +7

White dwarfs accreting planetary debris provide detailed insight into the bulk composition of rocky exo-planetesimals. However, only one Kuiper-Belt analogue has been identified in…

White dwarf pollution by hydrated planetary remnants: Hydrogen and Metals in WD J204713.76-125908.9

Matthew J. Hoskin, Odette Toloza, Boris T. Gänsicke +9

WD J204713.76-125908.9 is a new addition to the small class of white dwarfs with helium-dominated photospheres that exhibit strong Balmer absorption lines and atmospheric metal pol…

Fe I oscillator strengths for transitions from high-lying odd-parity levels

M. T. Belmonte, J. C. Pickering, M. P. Ruffoni +4

We report new experimental Fe I oscillator strengths obtained by combining measurements of branching fractions measured with a Fourier Transform spectrometer and time-resolved lase…

Lifetime measurements and oscillator strengths in singly ionised scandium and the solar abundance of scandium

A. Pehlivan Rhodin, M. T. Belmonte, L. Engstrom +8

The lifetimes of 17 even-parity levels (3d5s, 3d4d, 3d6s, and 4p) in the region 57743-77837 cm of singly ionised scandium (\ion{Sc}{ii}) were measured by two-step time-r…
