The Magnesium Isotopologues of MgH in the A(2)Pi-X-2 Sigma(+) System
Using laboratory hollow cathode spectra we have identified lines of the less common magnesium isotopologues of MgH, (MgH)-Mg-25 and (MgH)-Mg-26, in the A(2)Pi-X-2 Sigma(+) system. Based on the previous analysis of (MgH)-Mg-24, ...
Improved Log(gf) Values for Lines of Ti I and Abundance Determinations in the Photospheres of the Sun and Metal-Poor Star HD 84937 (Accurate Transition Probabilities for Ti I)
New atomic transition probability measurements for 948 lines of Ti I are reported. Branching fractions from Fourier transform spectra and from spectra recorded using a 3 m echelle spectrometer are combined with published ...
First Stars XVI. HST/STIS Abundances Of Heavy Elements In The Uranium-Rich Metal-Poor Star CS 31082-001
Context. The origin and site(s) of the r-process nucleosynthesis is(are) still not known with certainty, but complete, detailed r-element abundances off er our best clues. The few extremely metal-poor (EMP) stars with large ...
