DOI: 10.1093/mnras/stad1085
Abstract: Stellar ages are elusive to measure, albeit being very important for understanding stellar evolution. We investigate the impact of photospheric activity on 2-minute cadence lightcurves from the TESS/NASA mission of a selected sample of 30… read more here.

DOI: 10.1093/mnras/sty2791
Abstract: We have investigated the thorium (Th) abundance in a sample of 53 thin disc solar twins covering a wide range of ages. These data provide constrains on the mantle energy budget of terrestrial planets that… read more here.

Abstract: The present work aims to examine in detail the depletion of lithium in solar twins to better constrain stellar evolution models and investigate its possible connection with exoplanets. We employ spectral synthesis in the region… read more here.
