Is Liller 1 a building block of the Galactic bulge? -- Evidence with APOGEE
Anna Liptrott, Ricardo P. Schiavon, Andrew C. Mason +10
Liller 1 is a stellar system orbiting within the inner 0.8kpc of the Galactic centre, characterised by a wide spread in age and metallicity, indicating a high mass. Liller 1 has be…
Unveiling M33's Hidden Merger History: A Potential Population of Star Clusters on Retrograde Orbits
Borja Anguiano, Geraint F. Lewis, Steven R. Majewski
We report the discovery of a possible sub-population of stellar clusters that appear to follow retrograde orbits around the third largest galaxy in the Local Group, M33 (Triangulum…
Calibration of Binary Population Synthesis Models Using White Dwarf Binaries from APOGEE, GALEX and Gaia
A. C. Rubio, K. Breivik, C. Badenes +5
The effectiveness and stability of mass transfer in binaries system are crucial in determining its final product. Rapid binary population synthesis (BPS) codes simplify the complex…
Tidal Debris Candidates from the Centauri Accretion Event and its Role in Building Up the Milky Way Halo
Borja Anguiano, Arik Mitschang, Takanobu Kirihara +11
We identify stellar tidal debris from the Centauri ( Cen) system among field stars in the APOGEE survey via chemical tagging using a neural network trained on APOGEE obser…
Chemical tagging with APOGEE, MUSE, and HST: constraints on the formation of Centauri
Andrew C. Mason, Ricardo P. Schiavon, Sebastian Kamann +9
A plethora of evidence suggests that Centauri ( Cen) is the nuclear star cluster of a galaxy that merged with the Milky Way in early times. We use APOGEE, Gaia, MUSE, and…
