Cold, old and metal-poor: New stellar substructures in the Milky Way's dwarf spheroidals
V. Lora, E. K. Grebel, S. Schmeja +1
Dwarf spheroidal galaxies (dSph) orbiting the Milky Way are complex objects often with complicated star formation histories and internal dynamics. In this work, we search for stell…
Kron 3: a fourth intermediate age cluster in the SMC with evidence of multiple populations
K. Hollyhead, C. Lardo, N. Kacharov +6
We present the results of a spectroscopic study of the intermediate age (approximately 6.5 Gyr) massive cluster Kron 3 in the Small Magellanic Cloud. We measure CN and CH band stre…
Evidence for multiple populations in the intermediate age cluster Lindsay 1 in the SMC
K Hollyhead, N Kacharov, C Lardo +6
Lindsay 1 is an intermediate age (approx 8 Gyr) massive cluster in the Small Magellanic Cloud (SMC). Using VLT FORS2 spectra of 16 probable cluster members on the lower RGB of the…
Population gradients and photometric metallicities in early- and transition-type dwarf galaxies: Clues from the Sculptor group
S. Lianou, E. Grebel, G. S. Da Costa +3
We focus on the resolved stellar populations of one early- and four transition-type dwarf galaxies in the Sculptor group, with the aim to examine the potential presence of populati…
An abundance study of red-giant-branch stars in the Hercules dwarf spheroidal galaxy
D. Adén, K. Eriksson, S. Feltzing +3
Using high-resolution spectroscopy, we provide a determination of [Fe/H] and [Ca/H] for confirmed red-giant branch member stars of the Hercules dwarf spheroidal galaxy. Based on th…
A constant dark matter halo surface density in galaxies
F. Donato, G. Gentile, P. Salucci +6
We confirm and extend the recent finding that the central surface density r_0*rho_0 galaxy dark matter halos, where r_0 and rho_0 are the halo core radius and central density, is n…
