Gaia Focused Product Release: A catalogue of sources around quasars to search for strongly lensed quasars
Gaia Collaboration, A. Krone-Martins, C. Ducourant +398
Context. Strongly lensed quasars are fundamental sources for cosmology. The Gaia space mission covers the entire sky with the unprecedented resolution of " in the optical, ma…
Gaia Focused Product Release: Radial velocity time series of long-period variables
Gaia Collaboration, M. Trabucchi, N. Mowlavi +403
The third Gaia Data Release (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the publication of full radial-velocit…
Planets around evolved intermediate-mass stars III. Planet candidates and long-term activity signals in six open clusters
E. Delgado Mena, J. Gomes da Silva, J. P. Faria +6
[abridged]The aim of this work is to search for planets around evolved stars, with a special focus on stars more massive than 2\,M in light of previous findings that show a…
Search for lithium-rich giants in 32 open clusters with high-resolution spectroscopy
M. Tsantaki, E. Delgado-Mena, D. Bossini +3
