Near-Field cosmology with RR Lyrae variable stars: A first view of substructure in the southern sky
S. Duffau, A. K. Vivas, C. Navarrete +7
We present an update of a spectroscopic follow-up survey at low-resolution of a large number of RR Lyrae halo overdensity candidates found in the southern sky. The substructure can…
The Araucaria Project. On the Tip of the Red Giant Branch distance determination to the Magellanic Clouds
Marek Gorski, Grzegorz Pietrzynski, Wolfgang Gieren +8
We present a precise optical and near-infrared determination of the Tip of the Red Giant Branch (TRGB) brightness in the Large and Small Magellanic Clouds (respectively LMC and SMC…
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…
Pulsating hot O subdwarfs in Omega Cen: mapping a unique instability strip on the Extreme Horizontal Branch
S. K. Randall, A. Calamida, G. Fontaine +10
We present an extensive survey for rapid pulsators among Extreme Horizontal Branch (EHB) stars in omega Cen. The observations performed consist of nearly 100 hours of time-series p…
