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.…

Galactic tides and the outer density profile of the Sculptor and Ursa Minor dwarf spheroidals

Daniel A. Boyea, Julio F. Navarro, Jaclyn Jensen +1

Most dwarf spheroidal (dSph) satellites of the Milky Way follow exponential surface density profiles that decline sharply in the outer regions. The Sculptor (Scl) and Ursa Minor (U…

The galactic chemical evolution of carbon: Implications for stellar nucleosynthesis

Daniel A. Boyea, James W. Johnson, David H. Weinberg

Carbon (C) is thought to be produced by both core collapse supernovae (CCSN) and asymptotic giant branch (AGB) stars, but the relative contributions of these two sources are uncert…

The Yasone catalogue: three new Milky Way satellites and 17 further hypercompact candidates

J. Untzaga, M. Mezcua, S. Bonoli +5

We present the discovery of three new low-latitude (|b| ~ 20) Milky Way satellites: Yasone-1, Yasone-2, and Yasone-3. They were identified in our search for compact stell…

The Milky Way Radial Metallicity Gradient as an Equilibrium Phenomenon: Why Old Stars are Metal-Rich

James W. Johnson, David H. Weinberg, Guillermo A. Blanc +12

Metallicities of both gas and stars decline toward large radii in spiral galaxies, a trend known as the radial metallicity gradient. We quantify the evolution of the metallicity gr…
