The impact of Gaia in Lithium Depletion Boundary ages

  • 1. Centro de Estudios de Física del Cosmos de Aragón (CEFCA), Plaza San Juan 1, 44001 Teruel, Spain.

Description

We revise former LDB ages in several stellar associations consistently, taking advantage of the homogeneous Gaia parallaxes, and bolometric luminosity estimations that do not rely on monochromatic bolometric corrections.
We gathered all the available information from our data and the literature: membership, distances, photometric data, reddening, metallicity, and surface gravity.
We re-assigned membership, calculated bolometric luminosities and effective temperatures using distances derived from Gaia and multi-wavelength photometry for individual objects around the former LDB, and located the LDB using a homogeneous method for all the stellar associations. Finally, we estimated the age by comparing different evolutionary models.
