We present the abundances of magnesium (Mg) and silicon (Si) for 314 dwarf stars with spectral types in the interval K7.0-M5.5 (Teff range ~4200-3050 K) observed with the CARMENES high-resolution […]
![LEFT: M dwarf abundance distributions for Mg and Si separated according to the kinematic membership of stars in the thick disc (TD), thick disc-thin disc transition (TD-D), thin disc (D), and young disc (YD), following the criteria of Montes et al. (2018) (see text for details). Mean values for each population are indicated by vertical lines. RIGHT: Top panel: [Si/Fe] vs. firon. The target stars are in orange while the black points correspond to the firon values computed from the Adibekyan et al. (2012) abundances. The fit through the M dwarf values is denoted with a blue line. Bottom panel: Histogram for the firon values of our sample. -- astro-ph.SR](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/07/The-CARMENES-Search-For-Exoplanets-AroundM.png?resize=1200%2C716&ssl=1)
