On the Use of Field RR Lyrae as Galactic Probes. V. Optical and radial velocity curve templates
V. F. Braga, J. Crestani, M. Fabrizio +29
We collected the largest spectroscopic catalog of RR Lyrae (RRLs) including 20,000 high-, medium- and low-resolution spectra for 10,000 RRLs. We provide the analy…
On the use of field RR Lyrae as Galactic probes: IV. New insights into and around the Oosterhoff dichotomy
M. Fabrizio, V. F. Braga, J. Crestani +30
We discuss the largest and most homogeneous spectroscopic dataset of field RR Lyrae variables (RRLs) available to date. We estimated abundances using both high-resolution and low-r…
Metallicities from high resolution spectra of 49 RR Lyrae Variables
Christina K. Gilligan, Brian Chaboyer, Massimo Marengo +12
Accurate metallicities of RR Lyrae are extremely important in constraining period-luminosity-metallicity relationships (PLZ), particularly in the near-infrared. We analyse 69 high-…
On the Use of Field RR Lyrae as Galactic Probes. II. A new S calibration to estimate their metallicity
J. Crestani, M. Fabrizio, V. F. Braga +33
We performed the largest and most homogeneous spectroscopic survey of field RR Lyraes (RRLs). We secured 6,300 high resolution (HR, R35,000) spectra for 143 RRLs (11…
On the Metamorphosis of the Bailey diagram for RR Lyrae stars
G. Bono, V. F. Braga, J. Crestani +37
We collected over 6000 high-resolution spectra of four dozen field RR Lyrae (RRL) variables pulsating either in the fundamental (39 RRab) or in the first overtone (9 RRc) mode. We…
On the character of turbulence in self-consistent models of core-collapse supernovae
Jordi Casanova, Eirik Endeve, Eric J. Lentz +4
Neutrino-driven convection plays a crucial role in the development of core-collapse supernova (CCSN) explosions. However, the complex mechanism that triggers the shock revival and…
