Towards breaking the degeneracy between stellar ages and unresolved multiplicity
Friedrich Anders, Anna B. A. Queiroz, Sagar Malhotra +2
Stellar age is the central desirable parameter we need to disentangle different Galactic formation scenarios. Nevertheless, no stellar age dating method is completely model-indepen…
Chemo-dynamical Analysis of a CNO-Enhanced Ultra Metal-poor Star (): Insights into Early Enrichment by Faint Population III Supernova
Guilherme Limberg, Vinicius M. Placco, Alexander P. Ji +10
We report an independent identification of the ultra metal-poor (UMP) star () DR3 $\texttt{source_id}$ 4795913112968206720 (GDR3_479591) in the miss…
Modelling the Milky Way's exoplanet population based on cosmological galaxy simulations
Chloé Padois, Daniel del Ser, Friedrich Anders +7
In this paper we aim to simulate realistic exoplanet populations across different regions of the MW by combining state-of-the-art cosmological simulations of our Galaxy with exopla…
The oldest Milky Way stars: New constraints on the age of the Universe and the Hubble constant
Elena Tomasetti, Cristina Chiappini, Samir Nepal +6
We exploit the most robust, old, and cosmology-independent age estimates of individual stars from Gaia DR3 to place a lower bound on the age of the Universe, . These constrain…
The Nineteenth Data Release of the Sloan Digital Sky Survey
SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +210
Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…
The Spheroidal Bulge of the Milky Way: Chemodynamically Distinct from the Inner-Thick Disc and Bar
Samir Nepal, Cristina Chiappini, Angeles Pérez-Villegas +7
Studying the composition and origin of the inner region of our Galaxy -- the "Galactic bulge" -- is crucial for understanding the formation and evolution of the Milky Way and other…
Early Co-formation of the Milky Way's Thin and Thick Disks at Redshift z > 2
Lais Borbolato, Silvia Rossi, Hélio D. Perottoni +8
The Milky Way serves as a template for understanding the formation and evolution of late-type massive disk galaxies since we can obtain detailed chemical and kinematic information…
All-sky Kinematics and Chemistry of Monoceros Stellar Overdensity
Lais Borbolato, Hélio D. Perottoni, Silvia Rossi +7
We explore the kinematic and chemical properties of Monoceros stellar overdensity by combining data from 2MASS, WISE, APOGEE, and . Monoceros is a structure located to…
An all-sky proper motion map of the Sagittarius stream using Gaia DR2
T. Antoja, P. Ramos, C. Mateu +4
We aim to measure the proper motion along the Sagittarius stream that is the missing piece to determine its full 6D phase space coordinates. We conduct a blind search of over-densi…
The relationship between mono-abundance and mono-age stellar populations in the Milky Way disk
I. Minchev, M. Steinmetz, C. Chiappini +4
Studying the Milky Way disk structure using stars in narrow bins of [Fe/H] and [alpha/Fe] has recently been proposed as a powerful method to understand the Galactic thick and thin…
