The He abundance in NGC 1850 A and B: are we observing the early stage of formation of multiple populations in a stellar cluster?
R. Carini, A. Sollima, E. Brocato +1
We present the result of a sample of B-stars in the Large Magellanic Cloud young double stellar cluster NGC 1850 A and NGC 1850 B, observed with the integral-field spectrograph at…
Zero and extremely low metallicity rotating massive stars: evolution, explosion, and nucleosynthesis up to the heaviest nuclei
Lorenzo Roberti, Marco Limongi, Alessandro Chieffi
We present the evolution and the explosion of two massive stars, 15 and 25 M, spanning a wide range of initial rotation velocities (from 0 to 800 km/s) and three initial…
Analysis of full-disc H alpha observations: Carrington maps and filament properties in 1909-2022
Theodosios Chatzistergos, Ilaria Ermolli, Dipankar Banerjee +14
Full disc observations of the Sun in the H line provide information about the solar chromosphere and in particular about the filaments, which are dark and elongated features tha…
MgAl burning chain in Omega Centauri
Deimer Antonio Alvarez Garay, Alessio Mucciarelli, Michele Bellazzini +2
In this study, we report the results of Fe, Mg, Al, and Si abundances analysis for a sample of 439 stars in Omega Centauri, using high-resolution spectra obtained with the VLT/FLAM…
PENELLOPE V. The magnetospheric structure and the accretion variability of the classical T Tauri star HM Lup
A. Armeni, B. Stelzer, R. A. B. Claes +9
HM Lup is a young M-type star that accretes material from a circumstellar disk through a magnetosphere. Our aim is to study the inner disk structure of HM Lup and to characterize i…
TIC 43152097. The first eclipsing binary in NGC 2232
A. Frasca, J. Alonso-Santiago, G. Catanzaro +5
We report the discovery of a low-mass totally eclipsing system in the young (age28 Myr) open cluster NGC2232, during a scrutiny of their TESS light curves. The follow-up st…
