Empirical colour--effective temperature relations in the SDSS system from IRFM temperatures of GALAH and APOGEE stars
Zenghua Zhou, Luca Casagrande, Xiaobin Zhang +5
Reliable estimates of stellar effective temperature () are fundamental to stellar population studies and Galactic astrophysics. However, the majority of stars ob…
Rubin Data Preview 1: Extending the View of Unresolved Binary Stars in 47 Tucanae
Giacomo Cordoni, Luca Casagrande, Helmut Jerjen
Until now, the study of unresolved main sequence binary stars in globular clusters has been possible almost exclusively in their central regions with deep Hubble Space Telescope (H…
Spectro-Photometry and Radial Distribution of Multiple Stellar Populations in Globular Clusters from Gaia XP Spectra
V. J. Mehta, A. P. Milone, L. Casagrande +14
Understanding the formation of multiple populations in globular clusters (GCs) represents a challenge for stellar population studies. Nevertheless, the outermost cluster regions, l…
Shell helium-burning hot subdwarf B stars as candidates for blue large-amplitude pulsators
H. Xiong, L. Casagrande, X. Chen +7
Blue large-amplitude pulsators (BLAPs) are a newly discovered type of variable star. Their typical pulsation periods are on the order of a few tens of minutes, with relatively larg…
