The potential broader complex linked to the key Cepheid SV Vul
Daniel Majaess, Ignacio Negueruela, Leonid N. Berdnikov +10
A new distance was established to the Cepheid SV Vul () and its host cluster Alicante 13, and is tied in part to deeper UKIDSS-DR6 photometry and Gaia DR3 observatio…
Rare Find: Discovery and chemo-dynamical properties of two s-process enhanced RR Lyrae stars
Valentina D'Orazi, Giuliano Iorio, Borbála Cseh +15
We report the serendipitous discovery of two RR Lyrae stars exhibiting significant s-process element enrichment, a rare class previously represented solely by TY Gruis. Our goal is…
The Gaia parallax discrepancy for the cluster Pismis 19, and separating Scutis from Cepheids
Daniel Majaess, Charles J. Bonatto, David G. Turner +10
Pre-Gaia distances for the open cluster Pismis 19 disagree with Gaia parallaxes. A 2MASS red clump distance was therefore established for Pismis 19 ( kpc), whic…
Variable Star Light Curves in Koopman Space
Nicolas Mekhaël, Mario Pasquato, Gaia Carenini +4
We present the first application of data-driven techniques for dynamical system analysis based on Koopman theory to variable stars. We focus on light curves of RRLyrae type variabl…
The Wide-field Spectroscopic Telescope (WST) Science White Paper
Vincenzo Mainieri, Richard I. Anderson, Jarle Brinchmann +214
The Wide-field Spectroscopic Telescope (WST) is proposed as a new facility dedicated to the efficient delivery of spectroscopic surveys. This white paper summarises the initial con…
2D chemical evolution model: the impact of galactic disc asymmetries on azimuthal chemical abundance variations
E. Spitoni, G. Cescutti, I. Minchev +5
Galactic disc chemical evolution models generally ignore azimuthal surface density variation that can introduce chemical abundance azimuthal gradients. Recent observations, however…
