The GAPS Programme at the TNG: LXX. TOI-5734b: A hot sub-Neptune orbiting a relatively young K dwarf with an Earth-like density

S. Filomeno, T. Trifonov, M. Damasso +40

Increasing interest in young exoplanets is leading to a growing effort to understand the formation and evolutionary processes responsible for their different architectures. One int…

Ancient relic moderately metal-rich bulge cluster Tonantzintla 2

Sergio Ortolani, Stefano O. Souza, Domenico Nardiello +6

The assembly history of the Galactic bulge is intimately tied to the formation of the proto-Milky Way, yet reconstructing this early phase is difficult because mergers and secular…

A binary-related origin mediated by environmental conditions for blue straggler stars

Francesco R. Ferraro, Barbara Lanzoni, Enrico Vesperini +7

Blue stragglers are anomalously massive core hydrogen-burning stars that, according to the theory of single star evolution, should not exist. They are suspected to form in mass-enh…

Searching for Exoplanets Born Outside the Milky Way: VOYAGERS Survey Design

Robert Aloisi, Andrew Vanderburg, Melinda Soares-Furtado +44

Observations over the past few decades have found that planets are common around nearby stars in our Galaxy, but little is known about planets that formed outside the Milky Way. We…

Hidden Figures of Globular Clusters: Integrated Stellar Populations Impacted by Hot Subdwarfs

Thayse A. Pacheco, Paula R. T. Coelho, Lucimara P. Martins +8

Globular clusters (GCs) are fundamental for understanding the integrated light of old stellar populations and galaxy assembly processes. However, the role of hot, evolved stars, su…

JWST imaging of omega Centauri: II. Evidence for a split white dwarf cooling sequence in the near-infrared

M. Scalco, M. Salaris, L. R. Bedin +11

We present a detailed analysis of the white dwarf cooling sequence (WD CS) in omega Centauri based on combined Hubble Space Telescope (HST) and JWST observations. Our analysis conf…
