On the distance and reddening of the starburst galaxy IC10
N. Sanna, G. Bono, P. B. Stetson +16
We present deep and accurate optical photometry of the Local Group starburst galaxy IC10. The photometry is based on two sets of images collected with the Advanced Camera for Surve…
A large stellar evolution database for population synthesis studies. IV. Integrated properties and spectra
Susan M. Percival, Maurizio Salaris, Santi Cassisi +1
This paper is the 4th in a series describing the latest additions to the BaSTI stellar evolution database, which consists of a large set of homogeneous models and tools for populat…
The Horizontal Branch of NGC 1851: Constraints on the Cluster Subpopulations
M. Salaris, S. Cassisi, A. Pietrinferni
We investigate the distribution of stars along the Horizontal Branch of the Galactic globular cluster NGC1851, to shed light on the progeny of the two distinct Subgiant Branch popu…
Metallicity estimates of Galactic Cepheids based on Walraven photometry
S. Pedicelli, J. Lub, J. W. Pel +13
We present new empirical and theoretical calibrations of two photometric metallicity indices based on Walraven photometry. The empirical calibration relies on a sample of 48 Cephei…
The double Subgiant Branch of NGC 1851: the role of the CNO abundance
S. Cassisi, M. Salaris, A. Pietrinferni +4
We explore the possibility that the anomalous split in the Subgiant branch of the galactic globular cluster NGC 1851 is due to the presence of two distinct stellar populations with…
Stroemgren metallicity calibration: the m1, b-y relation
A. Calamida, G. Bono, P. B. Stetson +15
We performed a new calibration of the Stroemgren metallicity index m1 based on the b-y color of cluster red giant stars. The current Metallicity-Index-Color relation is not linear…
