On the use of field RR Lyrae as Galactic probes: I. The Oosterhoff dichotomy based on fundamental variables
M. Fabrizio, G. Bono, V. F. Braga +21
We collected a large data set of field RR Lyrae stars (RRLs) by using catalogues already available in the literature and Gaia DR2. We estimated the iron abundances for a sub-sample…
Infrared -band Photometry of Field RR Lyrae Variable Stars
Andrew C. Layden, Glenn P. Tiede, Brian Chaboyer +2
We present multi-epoch infrared photometry in the -band for 74 bright RR Lyrae variable stars tied directly to the 2MASS photometric system. We systematize additional -band…
Are the double-mode bulge RR Lyrae stars with identical period-ratios the relic of a disrupted stellar system?
Andrea Kunder, Alex Tilton, Dylon Maertens +6
Radial velocities of fifteen double-mode bulge RR Lyrae (RR01) stars are presented, six of which belong to a compact group of RR01 stars in pulsation space, with the ratio of first…
Exploring the nature and synchronicity of early cluster formation in the Large Magellanic Cloud IV: Evidence for Multiple Populations in Hodge 11 and NGC 2210
Christina K. Gilligan, Brian Chaboyer, Jeffrey D. Cummings +10
We present a multiple population search in two old Large Magellanic Cloud (LMC) Globular Clusters, Hodge 11 and NGC 2210. This work uses data from the Advanced Camera for Surveys a…
