Probing the early chemical evolution of the Sculptor dSph with purely old stellar tracers
C. E. Martínez-Vázquez, M. Monelli, C. Gallart +8
We present the metallicity distribution of a sample of 471 RR Lyrae (RRL) stars in the Sculptor dSph, obtained from the -band Period-Luminosity relation. It is the first time th…
The ACS LCID Project XI. On the early time resolution of LG dwarf galaxy SFHs: Comparing the effects of reionization in models with observations
Antonio Aparicio, Sebastian L. Hidalgo, Evan Skillman +10
The analysis of the early star formation history (SFH) of nearby galaxies, obtained from their resolved stellar populations is relevant as a test for cosmological models. However,…
The ISLANDS project I: Andromeda XVI, An Extremely Low Mass Galaxy not Quenched by Reionization
Matteo Monelli, Clara E. Martínez-Vázquez, Edouard J. Bernard +14
Based on data aquired in 13 orbits of HST time, we present a detailed evolutionary history of the M31 dSph satellite Andromeda XVI, including its life-time star formation history,…
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…
