Extending the Chemical Reach of the H3 Survey: Detailed Abundances of the Dwarf-galaxy Stellar Stream Wukong/LMS-1

Guilherme Limberg, Alexander P. Ji, Rohan P. Naidu +10

We present the first detailed chemical-abundance analysis of stars from the dwarf-galaxy stellar stream Wukong/LMS-1 covering a wide metallicity range ($-3.5 < \rm[Fe/H] \lesssim -…

The Chemodynamical Nature of the Triangulum-Andromeda Overdensity

Yuri Abuchaim, Hélio D. Perottoni, Silvia Rossi +7

We present a chemodynamical study of the Triangulum-Andromeda overdensity (TriAnd) employing a sample of 31 candidate stars observed with the GRACES high-resolution (=40,000) sp…

Phase-space Properties and Chemistry of the Sagittarius Stellar Stream Down to the Extremely Metal-poor () Regime

Guilherme Limberg, Anna B. A. Queiroz, Hélio D. Perottoni +6

In this work, we study the phase-space and chemical properties of Sagittarius (Sgr) stream, the tidal tails produced by the ongoing destruction of Sgr dwarf spheroidal (dSph) galax…

The Unmixed Debris of Gaia-Sausage/Enceladus in the Form of a Pair of Halo Stellar Overdensities

Hélio D. Perottoni, Guilherme Limberg, João A. S. Amarante +5

In the first billion years after its formation, the Galaxy underwent several mergers with dwarf satellites of various masses. The debris of Gaia-Sausage/Enceladus (GSE), the galaxy…

Abundance Patterns of and Neutron-capture Elements in the Helmi Stream

Guilherme Limberg, Rafael M. Santucci, Silvia Rossi +6

We identified 8 additional stars as members of the Helmi stream (HStr) in the combined GALAH+ DR3 and EDR3 catalog. By consistently reevaluating claimed members from the lit…
