Not all nitrogen-rich field stars originate from globular clusters
Ellen I. Leitinger, Andrea Miglio, Josefina Montalbán +7
Globular clusters (GCs) are important tracers of the early Galactic assembly process, with part of their stars showing distinct chemical abundance patterns. When such stars are fou…
Tracing back a second-generation star stripped from Terzan 5 by the Galactic bar
Stefano O. Souza, Marica Valentini, Cristina Chiappini +6
The Galactic bulge hosts the Milky Way's oldest stars, possibly coming from disrupted globular clusters (GCs) or the bulge's primordial building blocks, making these stars witnesse…
Discovery of the local counterpart of disc galaxies at z > 4: The oldest thin disc of the Milky Way using Gaia-RVS
Samir Nepal, Cristina Chiappini, Anna B. A. Queiroz +5
JWST has recently detected numerous disc galaxies at high-redshifts and there have been observations of cold disc galaxies at z > 4 with ALMA. In the Milky Way, recent studies find…
K2 results for "young" -rich stars in the Galaxy
V. Grisoni, C. Chiappini, A. Miglio +11
The origin of apparently young -rich stars in the Galaxy is still a matter of debate in Galactic archaeology, whether they are genuinely young or might be products of binary evo…
Beyond Gaia DR3: Tracing the [/M]-[M/H] bimodality from the inner to the outer Milky Way disc with Gaia-RVS and convolutional neural networks
G. Guiglion, S. Nepal, C. Chiappini +17
In June 2022, Gaia DR3 has provided the astronomy community with about one million spectra from the Radial Velocity Spectrometer (RVS) covering the CaII triplet region. However, on…
