No country for old stars -Spectroscopic confirmation of the first intermediate-age RR Lyrae in the open cluster Trumpler 5

Valentina D'Orazi, Cecilia Mateu, Giuliano Iorio +13

RR Lyrae stars are widely considered tracers of ancient (greater than 10 Gyr), metal-poor stellar populations. However, recent kinematic and photometric studies suggest the existen…

Systematic census of RR Lyrae stars in Milky Way stellar streams

Bruno Domínguez, Cecilia Mateu, Pau Ramos +1

Context. Nearly 150 tidal streams are known in the Milky Way, but full phase-space information exists for only a few. RR Lyrae stars (RRL), as standard candles, provide a powerful…

Hide and Seek with Gaia. Detectability of Predicted Thin-Disc Metal-Rich RR Lyrae Binaries in Gaia DR3 and DR4

Giuliano Iorio, Pranav Nagarajan, Alexey Bobrick +8

RR Lyrae stars (RRLs) are classical tracers of old stellar populations, yet growing evidence suggests the presence of a metal-rich ([Fe/H]>-0.5), intermediate-age (2-7 Gyr) sub-pop…

RR Lyrae stars trace the Milky Way warp

Mauro Cabrera-Gadea, Cecilia Mateu, Pau Ramos

The outskirts of the Milky Way disc have been known to be warped since the late 1950s. Although various stellar populations have shown an underlying warped distribution, the relati…

Structure, kinematics and time evolution of the Galactic Warp from Classical Cepheids

Mauro Cabrera-Gadea, Cecilia Mateu, Pau Ramos +11

The warp is a well-known undulation of the Milky Way disc. Its structure has been widely studied, but only since Gaia DR2 has it been possible to reveal its kinematic signature bey…

Full 5D characterisation of the Sagittarius stream with Gaia DR2 RR Lyrae

P. Ramos, C. Mateu, T. Antoja +4

The Sagittarius stream is one of the best tools that we currently have to estimate the mass and shape of our Galaxy. However, assigning membership and obtaining the phase-space dis…
