Characterizing the disruption of Böotes III: a missing link in the Galactic halo?
Jaclyn Jensen, Daniel A. Boyea, Alan W. McConnachie +14
The Böotes III (Boo3) dwarf galaxy has long been suspected of being the progenitor of Styx, a ~50°-long stellar stream that was simultaneously discovered in the same region of sky.…
Milky Way's Metal-Poor Stars display Chemical Transition near the Solar Radius
Khyati Malhan
The metal-poor stars of a galaxy offer insights into that galaxy's early formation processes and accretion history. Here, we investigate whether the metal-poor stars of our Milky W…
The Pristine Dwarf-Galaxy survey -- VI. A VLT/FLAMES spectroscopic study of the dwarf galaxy Boötes II
Nicolas Longeard, Pascale Jablonka, Giuseppina Battaglia +4
The Milky Way has a large population of dwarf galaxy satellites. Their properties are sensitive to both cosmology and the physical processes underlying galaxy formation, but these…
The Pristine survey: XXVII. The extremely metal-poor stream C-19 stretches over more than 100 degrees
Zhen Yuan, Tadafumi Matsuno, Tatyana Sitnova +14
The discovery of the most metal-poor stream, C-19, provides us with a fossil record of a stellar structure born very soon after the Big Bang. In this work, we search for new C-19 m…
The Pristine survey. XXVI. Chemical abundances of subgiant stars of the extremelymetal-poor stream C-19
P. Bonifacio, E. Caffau, P. François +17
Context: The C-19 stellar stream is the most metal-poor stream known to date. While its width and velocity dispersion indicate a dwarf galaxy origin, its metallicity spread and abu…
C-19 and Hot, Wide, Star Streams
Raymond G. Carlberg, Rodrigo Ibata, Nicolas F. Martin +4
The C-19 star stream has the abundance characteristics of an unusually metal poor globular cluster but kinematically is uncharacteristically hot and wide for a cluster stream, havi…
