Hint of bimodal Mg-Al anticorrelation in the metal-poor Globular Cluster NGC 4372
Camila Beltrand, Macarena Uribe, Sandro Villanova +1
We present a detailed chemical abundance analysis of seven red giant branch stars in the very metal-poor globular cluster NGC~4372, based on high-resolution UVES spectra. Our study…
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…
The Twentieth Data Release of the Sloan Digital Sky Survey: First All-Sky BOSS Spectra, eROSITA-SDSS-V Mapper Coordinated Observations, and a Preview of the Local Volume Mapper
SDSS Collaboration, Mojgan Aghakhanloo, David Aguilar +273
This paper presents the twentieth data release (DR20) from the Sloan Digital Sky Survey, the third data release of its fifth generation (SDSS-V). SDSS-V is a panoptic spectroscopy…
CAPOS: The bulge Cluster APOgee Survey XII. Abundances for 98 PIGS metal-poor Bulge field giants
Carolina Salgado, Sandro Villanova, Doug Geisler +1
The inner Milky Way hosts overlapping stellar populations (bar--bulge, inner thin and thick disks, and halo), complicating population assignments along the line of sight. A joint c…
TOI-159 b: an eccentric hot-Jupiter planet around a young, pulsating Doradus star
G. Mantovan, A. Llancaqueo Albornoz, A. Psaridi +16
Fast-rotating hot stars are challenging targets for exoplanet searches due to rotational broadening and stellar variability. Moreover, hot stars often exhibit pulsations, an additi…
Infrared photometry and CaT spectroscopy of the most metal-poor in-situ globular cluster VVV-CL001
W. Haro Moya, C. Moni Bidin, M. C. Parisi +11
Globular clusters in the Galactic bulge are difficult to study due to high extinction and severe crowding. VVV-CL001 is an old, metal-poor, and fast cluster in the inner bulge, who…
