Super-slowly rotating Ap (ssrAp) stars: Spectroscopic study
G. Mathys, D. L. Holdsworth, M. Giarrusso +3
To gain better understanding of the Ap stars with the longest rotation periods, we obtained high resolution spectra of a sample of super-slowly rotating Ap (ssrAp) star candidates…
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…
Cepheid Metallicity in the Leavitt Law (C- MetaLL) survey: VI: Radial abundance gradients of 29 chemical species in the Milky Way Disk
E. Trentin, G. Catanzaro, V. Ripepi +9
Classical Cepheids (DCEPs) are crucial for calibrating the extragalactic distance ladder, ultimately enabling the determination of the Hubble constant through the PL and PW relatio…
TESS photometry and CAOS spectroscopy of six eclipsing binaries with Am components
G. Catanzaro, A. Frasca, J. Alonso-Santiago +1
In this paper, we present the results of a comprehensive study of six eclipsing binaries whose components are confirmed or suspected Am stars. By combining long-term high-resolutio…
OGLE GD-CEP-0516: the most metal-poor lithium-rich Galactic Cepheid
G. Catanzaro, V. Ripepi, M. Salaris +1
Classical Cepheids (DCEPs) are important astrophysical objects not only as standard candles for the determination of the cosmic distance ladder but also as a test-bed for the stell…
Cepheid Metallicity in the Leavitt Law (C-MetaLL) Survey. V. New multiband (grizJHKs) Cepheid light curves and period-luminosity relations
A. Bhardwaj, V. Ripepi, V. Testa +8
We present homogeneous multiband (grizJHKs) time-series observations of 78 Cepheids including 49 fundamental mode variables and 29 first-overtone mode variables. These observations…
