The aim of this study is to understand whether the Lupus I cloud has more members than what has been claimed so far in the literature and gain a deeper insight into the global properties of the region. We selected our targets using the Gaia DR2 catalog based on their consistent kinematic properties with the Lupus I bona fide members. In our sample of twelve YSOs observed by X-shooter, we identified ten Lupus I members. We could not determine the membership status of two of our targets, namely Gaia DR2 6014269268967059840 and 2MASS J15361110-3444473 due to technical issues. We found out that four of our targets are accretors, among them, 2MASS J15551027-3455045, with a mass of ∼0.03 M<SUB>⊙</SUB>, is one of the least massive accretors in the Lupus complex identified to date. Several of our targets (including accretors) are formed in situ and off-cloud with respect to the main filaments of Lupus I; hence, our study may hint that there are diffused populations of M dwarfs around Lupus I main filaments. In this context, we would like to emphasize that our kinematic analysis with Gaia catalogs played a key role in identifying the new members of the Lupus I cloud. <P />Based on observations collected at the European Southern Observatory at Paranal under program 105.20P9.001.STAMPAenArticle10.1051/0004-6361/2022452612-s2.0-85149696360https://www.aanda.org/articles/aa/full_html/2023/03/aa45261-22/aa45261-22.htmlhttp://arxiv.org/abs/2301.04463v12023A&A...671A..46MFIS/05 - ASTRONOMIA E ASTROFISICA
