AlH lines in the blue spectrum of Proxima Centauri
(2022-11-30)
The recently-computed ExoMol line lists for isotopologues of AlH are used to analyse the blue spectrum (4000-4500 {\AA}) of Proxima Cen (M5.5 V). Comparison of the observed and computed spectra enables the identification ...
The metal rich abundance pattern - spectroscopic properties and abundances for 107 main-sequence stars
(2017-07-01)
We report results from the high resolution spectral analysis of the 107 metal rich (mostly [Fe/H]$\ge$7.67 dex) target stars from the Calan-Hertfordshire Extrasolar Planet Search program observed with HARPS. Using our ...
