Solar-stellar astrophysics and dark matter

open access: closedResearch in Astronomy and Astrophysics, 2012
In this review,we recall how stars contribute to the search for dark matter and the specific role of the Sun.We describe a more complete picture of the solar interior that emerges from neutrino detections,gravity and acoustic mode measurements of the Solar and Heliospheric Observatory (SOHO) satellite,becoming a reference for the most common stars in ...

Solar astrophysics: Ghettosis from, or symbiosis with, stellar and galactic astrophysics?

open access: closedSpace Science Reviews, 1976
The purpose of the paper is to show how the solar-stellar symbiotic approach has led to the modeling of a star as a concentration of matter and energy. By 'solar-stellar symbiosis' is meant the philosophy of investigation according to which one asks what change in our general understanding of stellar structure and of stellar spectroscopic diagnostics ...

Asteroseismology of 16 Kepler Solar-like Stars: Stellar Parameters and the Effects of Element Diffusion

Research in Astronomy and Astrophysics, 2023
Element diffusion has small but significant effects on the structure of the stellar interior. It is interesting to investigate the effects of element diffusion using asteroseismology.

Stellar Population Astrophysics (SPA) with the TNG. Non-local thermodynamic equilibrium atmospheric parameters and abundances of giant stars in 33 open clusters

Astronomy & Astrophysics
Open clusters serve as important tools for accurately studying the chemical evolution of the Milky Way. By combining precise chemical data from high-resolution spectra with information on their distances and ages, we can effectively uncover the processes

Stellar population astrophysics (SPA) with the TNG. The Phosphorus abundance on the young side of Milky Way

Monthly notices of the Royal Astronomical Society
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 obtained with GIANO-B.
