Tracing the Milky Way warp and spiral arms with classical Cepheids
B. Lemasle, H. N. Lala, V. Kovtyukh +10
Mapping the Galactic spiral structure is a difficult task since the Sun is located in the Galactic plane and because of dust extinction. For these reasons, molecular masers in radi…
A new and homogeneous metallicity scale for Galactic classical Cepheids II. The abundance of iron and alpha elements
R. da Silva, J. Crestani, G. Bono +18
Classical Cepheids are the most popular distance indicators and tracers of young stellar populations. The key advantage is that they are bright and they can be easily identified in…
The MAGIC project. III. Radial and azimuthal Galactic abundance gradients using classical Cepheids
V. Kovtyukh, B. Lemasle, G. Bono +7
Radial abundance gradients provide sound constraints for chemo-dynamical models of galaxies. Azimuthal variations of abundance ratios are solid diagnostics to understand their chem…
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…
A connection between the Ice-type model of Linus Pauling and the three-color problem
R. da Silva, O. S. Nakao, J. R. Drugowich de Felício
The ice-type model proposed by Linus Pauling to explain its entropy at low temperatures is here approached in a didactic way. We first present a theoretically estimated low-tempera…
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…
