The overlooked role of stellar variability in the extended main sequence of LMC intermediate-age clusters
Ricardo Salinas, Michael A. Pajkos, Jay Strader +2
Intermediate-age star clusters in the Large Magellanic Cloud show extended main sequence turn offs (MSTOs), which are not consistent with a canonical single stellar population. The…
Discovery of RR Lyrae Stars in the Nuclear Bulge of the Milky Way
D. Minniti, R. Contreras Ramos, M. Zoccali +4
Galactic nuclei, like the one of the Milky Way, are extreme places with high stellar densities and, in most cases, hosting a supermassive black hole. One of the scenarios proposed…
An AO-assisted variability study of four globular clusters
R. Salinas, R. Contreras Ramos, J. Strader +4
The image subtraction technique applied to study variable stars in globular clusters represented a leap in the number of new detections, with the drawback that many of these new li…
Mapping the outer bulge with RRab stars from the VVV Survey
F. Gran, D. Minniti, R. K. Saito +8
The VISTA Variables in the Vía Láctea (VVV) is a near-IR time-domain survey of the Galactic bulge and southern plane. One of the main goals of this survey is to reveal the 3D struc…
Multiple stellar populations in the globular cluster M3 (NGC 5272): a Strömgren perspective
Davide Massari, Emilio Lapenna, Angela Bragaglia +3
We present Strömgren photometry of the Galactic Globular Cluster M3 to study its multiple generations phenomenon. The use of different colour-magnitude diagrams and especially of t…
Level of helium enhancement among M3's horizontal-branch stars
A. A. R. Valcarce, M. Catelan, J. Alonso-García +2
(Abridged) The color and luminosity distribution of horizontal branch (HB) stars in globular clusters are sensitive probes of their original helium abundances. However, recent anal…
