New Near-Infrared light-curve templates for RR Lyrae variables
V. F. Braga, P. B. Stetson, G. Bono +34
We provide homogeneous optical (UBVRI) and near-infrared (JHK) time series photometry for 254 cluster (omega Cen, M4) and field RR Lyrae (RRL) variables. We ended up with more than…
On a new method to estimate distance, reddening and metallicity of RR Lyrae stars using optical/near-infrared (,,,,,) mean magnitudes: Centauri as a first test case
G. Bono, G. Iannicola, V. F. Braga +26
We developed a new approach to provide accurate estimates of metal content, reddening and true distance modulus of RR Lyrae stars (RRLs). The method is based on homogeneous optical…
Chemical Compositions of Field and Globular Cluster RR Lyrae Stars: I. NGC 3201
D. Magurno, C. Sneden, V. F. Braga +7
We present a detailed spectroscopic analysis of horizontal branch stars in the globular cluster NGC 3201. We collected optical (4580-5330 A), high resolution (~34,000), high signal…
MuSCAT2: four-color Simultaneous Camera for the 1.52-m Telescopio Carlos Sánchez
Norio Narita, Akihiko Fukui, Nobuhiko Kusakabe +19
We report the development of a 4-color simultaneous camera for the 1.52~m Telescopio Carlos Sánchez (TCS) in the Teide Observatory, Canaries, Spain. The new instrument, named MuSCA…
Variable Stars in Local Group Galaxies. IV. RR Lyrae stars in the central regions of the low-density galaxy Crater II
M. Monelli, A. R. Walker, C. E. Martìnez-Vàzquez +9
We present a search and analysis of variable stars in the recently discovered Crater~II dwarf galaxy. Based on , , data collected with the Isaac Newton Telescope (FoV$\si…
On the early evolution of Local Group dwarf galaxy types: star formation and supernova feedback
Jose R. Bermejo-Climent, Giuseppina Battaglia, Carme Gallart +8
According to star formation histories (SFHs), Local Group dwarf galaxies can be broadly classified in two types: those forming most of their stars before () and t…
