First direct detection of an RR Lyrae star conclusively associated with an intermediate-age cluster
Cecilia Mateu, Bolivia Cuevas-Otahola, Juan José Downes
RR Lyrae stars have long been considered unequivocal tracers of old (>10 Gyr) and metal-poor () stellar populations. First, because these populations are wher…
Inferring Stellar Densities with Flexible Models I: The Distribution of RR Lyrae in the Milky Way with DR3
Madeline Lucey, Cecilia Mateu, Adrian Price-Whelan +3
Understanding the formation and evolutionary history of the Milky Way requires detailed mapping of its stellar components, which preserve fossil records of the Galaxy's assembly th…
The stellar initial mass function of nearby young moving groups
Rafael Bertolotto-Stefanelli, Juan José Downes, Genaro Suárez +3
The solar neighbourhood is populated by nearby, young moving groups (NYMGs) of stars that are candidates to be remnants of individual stellar clusters and associations, currently d…
RR Lyrae Stars in Intermediate-age Magellanic Clusters: Membership Probabilities and Delay Time Distribution
Bolivia Cuevas-Otahola, Cecilia Mateu, Ivan Cabrera-Ziri +4
Recent works have challenged our canonical view of RR Lyrae (RRL) stars as tracers of exclusively old populations (~Gyr) by proposing a fraction of these stars to be of…
The Dog that Didn't Bark: Non-Variable Field Stars in the RR Lyrae Instability Strip
Yuxi Lu, Cecilia Mateu, K. Z. Stanek
RR Lyrae stars (RRLs) are easy to identify thanks to their large photometric variation and short periods. All stars in the RRL instability strip are pulsators is often a hidden ass…
