Extremely metal-poor stars in the Fornax and Carina dwarf spheroidal galaxies
R. Lucchesi, P. Jablonka, Á. Skúladóttir +6
We present our analysis of VLT/UVES and X-shooter observations of six very metal-poor stars, including four stars at [Fe/H] in the Fornax and Carina dwarf spheroidal (…
The Pristine Inner Galaxy Survey (PIGS) VIII: Characterising the orbital properties of the ancient, very metal-poor inner Milky Way
Anke Ardern-Arentsen, Giacomo Monari, Anna B. A. Queiroz +19
The oldest stars in the Milky Way (born in the first few billion years) are expected to have a high density in the inner few kpc, spatially overlapping with the Galactic bulge. We…
Probing the early Milky Way with GHOST spectra of an extremely metal-poor star in the Galactic disk
Anya Dovgal, Kim A. Venn, Federico Sestito +31
Pristine_183.6849+04.8619 (P1836849) is an extremely metal-poor ([Fe/H]) star on a prograde orbit confined to the Galactic disk. Such stars are rare and may have their…
The Pristine survey -- XXII. A serendipitous discovery of an extremely Li-rich very metal-poor giant and a new method of Li/Li isotope measurement
T. M. Sitnova, T. Matsuno, Z. Yuan +5
We report the serendipitous discovery of a very metal-poor (VMP) Li-rich giant star ( = 469080 K, log g = 1.340.13, [Fe/H] = 0.07). We analyse the…
Gaia's brightest very metal-poor (VMP) stars. Metallicity catalogue of a thousand VMP stars from Gaia's radial velocity spectrometer spectra
Akshara Viswanathan, Else Starkenburg, Tadafumi Matsuno +10
Context. Gaia DR3 has offered the scientific community a remarkable dataset of approximately one million spectra acquired with the Radial Velocity Spectrometer (RVS) in the Calcium…
Small-scale stellar haloes: detecting low surface brightness features in the outskirts of Milky Way dwarf satellites
Jaclyn Jensen, Christian R. Hayes, Federico Sestito +5
Dwarf galaxies are valuable laboratories for dynamical studies related to dark matter and galaxy evolution, yet it is currently unknown just how physically extended their stellar c…
