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…
High-Precision Near-Infrared Abundances of Solar Analogs in the YJ Bands
Noriyuki Matsunaga, Takuji Tsujimoto, Daisuke Taniguchi +12
We present a near-infrared abundance analysis of 46 solar analogs with known ages, observed with the WINERED WIDE-mode spectrograph at a resolution of . Using an empi…
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…
The dwarf irregular galaxy NGC 6822. II. Young, intermediate and old stellar populations: comparison between theory and observations
Maria Tantalo, Giuseppe Bono, Maurizio Salaris +14
This paper presents a quantitative analysis of the stellar content in the Local Group dwarf irregular galaxy NGC 6822 by comparing stellar evolution models and observations in colo…
The elderly among the oldest: new evidence for extremely metal-poor RR Lyrae stars
Valentina D'Orazi, Vittorio F. Braga, Giuseppe Bono +21
We performed a detailed spectroscopic analysis of three extremely metal-poor RR Lyrae stars, exploring uncharted territories at these low metallicities for this class of stars. Usi…
The GALAH survey: Tracing the Milky Way's formation and evolution through RR Lyrae stars
Valentina D'Orazi, Nicholas Storm, Andrew R. Casey +39
Stellar mergers and accretion events have been crucial in shaping the evolution of the Milky Way (MW). These events have been dynamically identified and chemically characterised us…
Stellar population astrophysics (SPA) with the TNG: Measurement of the He I 10830Å line in the open cluster Stock 2
Mingjie Jian, Xiaoting Fu, Noriyuki Matsunaga +10
The precise measurement of stellar abundances plays a pivotal role in providing constraints on the chemical evolution of the Galaxy. However, before spectral lines can be employed…
Exploring Be phenomena in OBA stars: a Mid-infrared search
Mingjie Jian, Noriyuki Matsunaga, Biwei Jiang +2
As early-type stars with a rotation speed close to their critical velocity, Be stars experience an event called the Be phenomenon. The material in their equator is ejected into out…
