Dissipationless Formation and Evolution of the Milky Way Nuclear Star Cluster
In one widely discussed model for the formation of nuclear star clusters (NSCs), massive globular clusters spiral into the center of a galaxy and merge to form the nucleus. It is now known that at
Gaia Early Data Release 3
Context. We present the early installment of the third Gaia data release, Gaia EDR3, consisting of astrometry and photometry for 1.8 billion sources brighter than magnitude 21, complemented with the
Gaia unveils the kinematics of multiple stellar populations in 47 Tucanae
The series of events, which occurred at high redshift and originated multiple stellar populations in Globular Clusters (GCs) are still poorly understood. Theoretical work suggests that the
A primordial origin for the compositional similarity between the Earth and the Moon
TLDR
Track the feeding zones of growing planets in a suite of simulations of planetary accretion, to measure the composition of Moon-forming impactors and finds that different planets formed in the same simulation have distinct compositions, but the compositions of giant impactors are statistically more similar to the planets they impact.

Gaia Early Data Release 3
We produce a clean and well-characterised catalogue of objects within 100\,pc of the Sun from the \G\ Early Data Release 3. We characterise the catalogue through comparisons to the full data release,
Detailed Abundances in the Galactic Center: Evidence of a Metal-rich Alpha-enhanced Stellar Population
We present a detailed study of the composition of 20 M giants in the Galactic center with 15 of them confirmed to be in the Nuclear Star Cluster. As a control sample we have also observed 7 M giants
Mergers, tidal interactions, and mass exchange in a population of disc globular clusters
We present the results of a self-consistent N-body simulation following the evolution of a primordial population of thick-disc globular clusters (GCs). We study how the internal properties of such
The composition of Solar system asteroids and Earth/Mars moons, and the Earth–Moon composition similarity
[abridged] In the typical giant-impact scenario for the Moon formation most of the Moon's material originates from the impactor. Any Earth-impactor composition difference should, therefore,
Mergers, tidal interactions, and mass exchange in a population of disc globular clusters
Globular clusters (GCs), the oldest stellar systems observed in the Milky Way, have long been considered single stellar populations. As such, they provided an ideal laboratory to understand stellar
