Relocating Nonlinearity: How a Downstream Learner Reshapes What Genetic Programming Must Evolve
Nam H. Le
Genetic programming was conceived as a way of evolving solutions: the program is the answer, and fitness is the error of its own output. A substantial line of work instead makes th…
On the use of field RR Lyrae as Galactic probes:. IX. Radial velocities
K. Baeza-Villagra, V. F. Braga, M. Fabrizio +25
We present the largest and most homogeneous catalog of radial velocity (RV) measurements for field RR Lyrae (RRL) variables, based on both proprietary and publicly available spectr…
Stellar Population Astrophysics (SPA) with the TNG. Beyond the iron peak: Galactic evolution of molybdenum, ruthenium and zirconium through open clusters
Natalia Alvarez-Baena, Valentina D'Orazi, Christopher Sneden +11
Context: Open clusters serve as key laboratories for studying the chemical evolution of the Milky Way. In particular, leveraging these coeval groups of stars to study elements beyo…
No country for old stars -Spectroscopic confirmation of the first intermediate-age RR Lyrae in the open cluster Trumpler 5
Valentina D'Orazi, Cecilia Mateu, Giuliano Iorio +13
RR Lyrae stars are widely considered tracers of ancient (greater than 10 Gyr), metal-poor stellar populations. However, recent kinematic and photometric studies suggest the existen…
On the Use of Field RR Lyrae as Galactic Probes -- VIII. Early Formation of the Galactic Spheroid
G. Bono, V. F. Braga, M. Fabrizio +54
We introduce a new photometric catalog of RR Lyrae variables (RRLs, 300,000) mainly based on data available in public datasets. We also present the largest and most homogeneo…
Classical Cepheids in the Galactic thin disk I. Abundance gradients via non-local thermodynamic equilibrium spectral analysis
Antonino Nunnari, Valentina D'Orazi, Giuliana Fiorentino +23
Classical Cepheids (CCs) have long been considered excellent tracers of the chemical evolution of the Milky Way's young disk. We present a homogeneous, NLTE spectroscopic analysis…
Stellar population astrophysics (SPA) with the TNG. The Phosphorus abundance on the young side of MilkyWay
Mingjie Jian, Xiaoting Fu, Valentina D'Orazi +11
We present phosphorus abundance measurements for a total of 102 giant stars, including 82 stars in 24 open clusters and 20 Cepheids, based on high-resolution near-infrared spectra…
