K dwarfs and the chemical evolution of the Solar cylinder
E. Kotoneva, C. Flynn, C. Chiappini +1
K-dwarfs have life-times older than the present age of the Galactic disc, and are thus ideal stars to investigate the disc's chemical evolution. We have developed several photometr…

Luminosity-metallicity relation for stars on the lower main sequence
Eira Kotoneva, Chris Flynn, Raul Jimenez
We present a comparison of the predictions of stellar models with the luminosity of the lower main sequence () using K dwarfs in the Hipparcos catalog. The paralla…

Metallicities of nearby K-dwarfs
Eira Kotoneva, Chris Flynn
The so-called ``G-dwarf problem'' emerged in the 1960's when it was noticed that the observed metal distribution of nearby stars differs from what is expected in simple models of t…
