We extend the methodology introduced by Jahandar et al. (2024) to determine the effective temperature and chemical abundances of 31 slowly-rotating solar neighborhood M dwarfs (M1-M5) using high-resolution spectra from […]
![Top panel: Comparison of our determined [Fe/H] values (blue line) against the reported metallicity from Mann et al. (2015), Passegger et al. (2019), Maldonado et al. (2020), Marfil et al. (2021) and Cristofari et al. (2022). The red shaded area represents the typical distribution of M dwarfs metallicity from SDSS DR18 (Almeida et al. 2023). Bottom panel: Residuals are plotted to compare the median metallicity values from all referenced studies against each individual work. All measurements are consistent. -- astro-ph.SR](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/11/Chemical-Fingerprints-of-M-Dwarfs.png?resize=1200%2C717&ssl=1)
