Something new under the Sun: A magnetically driven CH/CN anti-correlation
Y. Momany, L. Monaco, S. Villanova +11
Spectroscopic monitoring surveys have shown that the magnetic cycle alters the photospheric structure of the Sun, perturbing the formation of molecular lines. In parallel, the stud…
New members of the Lupus I cloud based on Gaia astrometry Physical and accretion properties from X-Shooter spectra
F. Z. Majidi, J. M. Alcala', A. Frasca +13
We characterize twelve young stellar objects (YSOs) located in the Lupus I region, spatially overlapping with the Upper Centaurus Lupus (UCL) sub-stellar association. The aim of th…
A Plague of Magnetic Spots Among the Hot Stars of Globular Clusters
Yazan Al Momany, Simone Zaggia, Marco Montalto +15
Six decades and counting, the formation of hot ~20,000-30,000 K Extreme Horizontal Branch (EHB) stars in Galactic Globular Clusters remains one of the most elusive quests in stella…
A PSF-based Approach to TESS High quality data Of Stellar clusters (PATHOS) -- I. Search for exoplanets and variable stars in the field of 47 Tuc
D. Nardiello, L. Borsato, G. Piotto +9
The TESS mission will survey ~85 % of the sky, giving us the opportunity of extracting high-precision light curves of millions of stars, including stellar cluster members. In this…
A hot horizontal branch star with a close K-type main-sequence companion
C. Moni Bidin, Y. Momany, M. Montalto +4
Dynamical interactions in binary systems are thought to play a major role in the formation of extreme horizontal branch stars (EHBs) in the Galactic field. However, it is still unc…
The first search for variable stars in the open cluster NGC 6253 and its surrounding field
Fabrizio De Marchi, Ennio Poretti, Marco Montalto +2
This work presents the first high-precision variability survey in the field of the intermediate-age, metal--rich open cluster NGC 6253. Clusters of this type are benchmarks for ste…
