Stellar Population Astrophysics (SPA) with TNG [PDF]
Astronomy & Astrophysics, 2020 Context. Open clusters are excellent tracers of the chemical evolution of the Galactic disc. The spatial distribution of their elemental abundances, through the analysis of high-quality and high-resolution spectra, provides insight into the chemical ...

Stellar population astrophysics (SPA) with the TNG [PDF]
Astronomy & Astrophysics, 2019 Context. Open clusters exquisitely track the Galactic disc chemical properties and its time evolution; a substantial number of studies and large spectroscopic surveys focus mostly on the chemical content of relatively old clusters (age ≳ 1 Gyr ...

Stromlo Stellar Tracks: the importance of non-Solar scaled abundances for massive stars
, 2021 I present the Stromlo Stellar Tracks [1], a set of stellar evolutionary tracks for massive stars (>10 M ), computed by modifying the Modules for Experiments in Stellar Astrophysics (MESA) 1D stellar evolution package, to fit the Galactic Concordance ...

A Comparison between Physics-based and Polytropic MHD Models for Stellar Coronae and Stellar Winds of Solar Analogs [PDF]
, 2017 The development of the Zeeman–Doppler Imaging (ZDI) technique has provided synoptic observations of surface magnetic fields of low-mass stars. This led the stellar astrophysics community to adopt modeling techniques that have been used in solar physics ...

25 Years of Self-Organized Criticality: Solar and Astrophysics [PDF]
Space Science Reviews, 2014 Shortly after the seminal paper “Self-Organized Criticality: An explanation of 1/fnoise” by Bak et al. (1987), the idea has been applied to solar physics, in “Avalanches and the Distribution of Solar Flares” by Lu and Hamilton (1991).

The HARPS search for southern extra-solar planets [PDF]
Astronomy & Astrophysics, 2015 Context. Planetary companions of a fixed mass induce larger amplitude reflex motions around lower-mass stars, which helps make M dwarfs excellent targets for extra-solar planet searches. State of the art velocimeters with $\sim$1m/s stability can detect very low-mass planets out to the habitable zone of these stars.
