A critical analysis of main-sequence fitting in open clusters to derive the helium-to-metal enrichment ratio $Δ Y /Δ Z$

G. Valle, N. Ricci, M. Dell'Omodarme +3

We aim to investigate the feasibility of accurately determining the helium-to-metal enrichment ratio $Δ Y /Δ Z$ for open clusters using Gaia DR3 photometry. To test the reliability of…
