Short period variability in the globular cluster NGC 419 and the SMC field
Clara E. Martinez-Vazquez, Ricardo Salinas, A. Katherina Vivas
Delta Scuti ( Sct) stars have been extensively studied in our Galaxy, but far less in extragalactic systems. Here we study the population of Sct variables in NGC 419, an int…
Stellar variability at the main-sequence turnoff of the intermediate-age LMC cluster NGC 1846
R. Salinas, M. A. Pajkos, A. K. Vivas +2
Intermediate-age star clusters in the LMC present extended main sequence turnoffs (MSTO) that have been attributed to either multiple stellar populations or an effect of stellar ro…
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…
Dynamics of the NGC 4636 globular cluster system II. Improved constraints from a large sample of globular cluster velocities
Ylva Schuberth, Tom Richtler, Michael Hilker +3
We present new radial velocities for 289 globular clusters around NGC 4636, the southernmost giant elliptical galaxy of the Virgo cluster. The data were obtained with FORS2/MXU at…
