First planetesimals from DESI DR1: 12 highly metal-rich white dwarfs
Paula Izquierdo, Andrew Swan, Boris T. Gänsicke +43
The paper analyzes 12 highly metal‑rich white dwarfs from DESI DR1, measuring their photospheric metal abundances to infer the bulk composition of the accreted planetary debris, wh…
Mapping the Milky Way with Gaia Bp/Rp spectra II: The inner stellar halo traced by a large sample of blue horizontal branch stars
Wenbo Wu, Xianhao Ye, C. Allende Prieto +7
We selected BHB stars based on synthetic photometry and stellar atmosphere parameters inferred from Gaia Bp/Rp spectra. We generated the synthetic SDSS broad-band and Pristin…
The Pristine Inner Galaxy Survey (PIGS) XI: Revealing the chemical evolution of the interacting Sagittarius dwarf galaxy
Sara Vitali, Alvaro Rojas-Arriagada, Paula Jofré +9
The Sagittarius dwarf spheroidal galaxy (Sgr dSph) is a satellite orbiting the Milky Way that has experienced multiple stripping events due to tidal interactions with our Galaxy. I…
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…
The Pristine survey: XXV. The very metal-poor Galaxy: Chemodynamics through the follow-up of the Pristine-Gaia synthetic catalogue
Akshara Viswanathan, Zhen Yuan, Anke Ardern-Arentsen +27
The Pristine-\textit{Gaia} synthetic catalogue provides reliable photometric metallicities for 30 million FGK stars using the Pristine survey model and Gaia XP spectra. We pe…
Mapping the Milky Way with Gaia Bp/Rp spectra I: Systematic flux corrections and atmospheric parameters for 68 million stars
Xianhao Ye, Wenbo Wu, Carlos Allende Prieto +8
Gaia Bp/Rp spectra for over two hundred million stars have great potential for mapping metallicity across the Milky Way. We aim to construct an alternative catalog of atmospheric p…
