Optical spectroscopic signatures of the red giant evolutionary state
Ella Xi Wang, Melissa Ness, Thomas Nordlander +17
Modern spectroscopic surveys output large data volumes. Theoretical models provide a means to transform the information encoded in these data to measurements of physical stellar pr…
Abundance Measurements of the Metal-poor M subdwarf LHS 174 Using High-resolution Optical Spectroscopy
Neda Hejazi, Sebastien Lepine, Thomas Nordlander +3
Metal-poor M subdwarfs are among the oldest stellar populations and carry valuable information about the chemical enrichment history of the Milky Way. The measurements of chemical…
A Main Sequence CH-star in the globular cluster M55 (NGC 6809)
G. S. Da Costa, T. Nordlander
Spectra have been obtained with multi-fibre instrument 2dF on the Anglo-Australian Telescope of 89 candidate main sequence stars in the globular cluster M55 (NGC 6809). Radial velo…
A simple model for spectroscopic analyses of active stars
T. Nordlander, M. Baratella, L. Spina +1
Spectroscopic analyses of young late-type stars suffer from systematic inaccuracies, typically under-estimating metallicities but over-estimating abundances of certain elements inc…
Metallicities for more than 10 million stars derived from Gaia BP/RP spectra
T. Xylakis-Dornbusch, N. Christlieb, T. T. Hansen +3
Context. The third Gaia Data Release, which includes BP/RP spectra for 219 million sources, has opened a new window in the exploration of the chemical history and evolution of the…
Cool and Data-Driven: An Exploration of Optical Cool Dwarf Chemistry with Both Data-Driven and Physical Models
Adam D. Rains, Thomas Nordlander, Stephanie Monty +6
Detailed chemical studies of F/G/K -- or Solar-type -- stars have long been routine in stellar astrophysics, enabling studies in both Galactic chemodynamics, and exoplanet demograp…
