RR Lyrae Stars Belonging to the Candidate Globular Cluster Patchick 99
Evan Butler, Andrea Kunder, Zdenek Prudil +16
Patchick 99 is a candidate globular cluster located in the direction of the Galactic bulge, with a proper motion almost identical to the field and extreme field star contamination.…
The -Process Alliance: Fourth Data Release from the Search for -Process-Enhanced Stars in the Galactic Halo
Erika M. Holmbeck, Terese T. Hansen, Timothy C. Beers +22
This compilation is the fourth data release from the -Process Alliance (RPA) search for -process-enhanced stars, and the second release based on "snapshot" high-resolution ($…
On the Metamorphosis of the Bailey diagram for RR Lyrae stars
G. Bono, V. F. Braga, J. Crestani +37
We collected over 6000 high-resolution spectra of four dozen field RR Lyrae (RRL) variables pulsating either in the fundamental (39 RRab) or in the first overtone (9 RRc) mode. We…
The Bulge Radial Velocity Assay for RR Lyrae stars (BRAVA-RR) DR2: a Bimodal Bulge?
Andrea Kunder, Angeles Perez-Villegas, R. Michael Rich +11
Radial velocities of 2768 fundamental mode RR Lyrae stars (RRLs) toward the Southern Galactic bulge are presented, spanning the southern bulge from -8 < l < +8 and -3 < b <-6. Dist…
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…
The R-Process Alliance: Discovery of a low-alpha, r-Process-Enhanced Metal-Poor Star in the Galactic Halo
Charli M. Sakari, Ian U. Roederer, Vinicius M. Placco +24
A new moderately r-process-enhanced metal-poor star, RAVE J093730.5-062655, has been identified in the Milky Way halo as part of an ongoing survey by the R-Process Alliance. The te…
