To Grow Old and Peculiar: A Survey of Anomalous Variable Stars in M80 and Age Determination using K2 and Gaia
László Molnár, Emese Plachy, Attila Bódi +11
The globular cluster Messier 80 was monitored by the Kepler space telescope for 80 days during the K2 mission. Continuous, high-precision photometry of such an old, compact cluster…
Spectroscopy of LMC Cluster Stars
Andrea K. Dupree, Christian I. Johnson, Mario Mateo +1
High resolution spectra of stars in the ~200 Myr LMC globular cluster, NGC 1866, reveal rapidly rotating stars with variable H-alpha emission and absorption, and signatures of outf…
A comparative study of two 47 Tuc giant stars with different s-process enrichment
M. J. Cordero, C. J. Hansen, C. I. Johnson +1
Here we aim to understand the origin of 47 Tuc's La-rich star Lee 4710. We report abundances for O, Na, Mg, Al, Si, Ca, Sc, Ti, V, Cr, Co, Ni, Zn, Y, Zr, Ba, La, Ce, Pr, Nd, and Eu…
A high-velocity bulge RR Lyrae variable on a halo-like orbit
Andrea Kunder, R. Michael Rich, Keith Hawkins +21
We report on the RR Lyrae variable star, MACHO 176.18833.411, located toward the Galactic bulge and observed within the data from the ongoing Bulge RR Lyrae Radial Velocity Assay (…
