On the Use of Field RR Lyrae as Galactic Probes. VI. Mixed mode RR Lyrae variables in Fornax and in nearby dwarf galaxies
V. F. Braga, G. Fiorentino, G. Bono +11
We investigate the properties of the mixed-mode (RRd) RR Lyrae (RRL) variables in the Fornax dwarf spheroidal (dSph) galaxy by using - and -band time series collected over tw…
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…
Rubin Observatory LSST Transients and Variable Stars Roadmap
Kelly M. Hambleton, Federica B. Bianco, Rachel Street +79
The Vera C. Rubin Legacy Survey of Space and Time holds the potential to revolutionize time domain astrophysics, reaching completely unexplored areas of the Universe and mapping va…
New theoretical Period-Luminosity-Metallicity relations for RR Lyrae in the Rubin-LSST filters
Marcella Marconi, Roberto Molinaro, Massimo Dall'Ora +8
The revolutionary power of future Rubin-LSST observations will allow us to significantly improve the physics of pulsating stars, including RR Lyrae. In this context, an updated the…
On the dwarf irregular galaxy NGC 6822. I. Young, intermediate and old stellar populations
Maria Tantalo, Massimo Dall'Ora, Giuseppe Bono +13
We present accurate and deep multi-band () photometry of the Local Group dwarf irregular galaxy NGC 6822. The images were collected with wide field cameras at 2m/4m- (INT,CT…
Metallicity of Galactic RR Lyrae from Optical and Infrared Light Curves: II. Period-Fourier-Metallicity Relations for First Overtone RR Lyrae
Joseph P. Mullen, Massimo Marengo, Clara E. Martínez-Vázquez +11
We present new period--[Fe/H] relations for first overtone RRL stars (RRc), calibrated over a broad range of metallicities () utilizing the lar…
Optimal Differential Astrometry for Multiconjugate Adaptive Optics. I. Astrometric Distortion Mapping using On-sky GeMS Observations of NGC 6723
Mojtaba Taheri, Alan W. McConnachie, Paolo Turri +7
The Extremely Large Telescope and the Thirty Meter Telescope will use state of the art multiconjugate adaptive optics (MCAO) systems to obtain the full D4 advantage that their aper…
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…
