Abstract: The innermost portions of the Milky Way’s stellar halo have avoided scrutiny until recently. The lack of wide-area survey data, made it difficult to reconstruct an uninterrupted view of the density distribution of the metal-poor stars inside the Solar radius. In this study, we utilize red giant branch (RGB) stars from Gaia, with metallicities estimated using spectro-photometry from Gaia Data Release 3. Accounting for Gaia’s selection function, we examine the spatial distribution of metal-poor ([M/H]arXiv:2410.22250v1 Announce Type: new
