Hot Degenerate Components in Blue Stragglers: A Multi-Wavelength SED Analysis of Nine Open Clusters with Swift/UVOT
Deniz Cennet Çınar, D. Bisht, Selçuk Bilir +2
We present a homogeneous multi-wavelength analysis of 35 blue straggler star (BSS) candidates in nine open clusters, combining Swift/UVOT near-ultraviolet data with Gaia DR3 astrom…
Hunting white dwarfs at the center of planetary nebulae
Javier Ahumada, Walter Weidmann, Marcelo Miller Bertolami +1
We present Gemini-South observations of nine faint and extended planetary nebulae. Using direct images taken with the spectrograph GMOS, we built the vs. di…
Breaking the dichotomy between typical and anomalous globular clusters: the case of NGC 3201
Bruno Dias, Ignacio Araya, João Paulo Nogueira-Cavalcante +2
We recently discovered that NGC 3201 has characteristics that set it outside the current twofold classification scheme for Galactic globular clusters (GCs). Most GCs are mono-metal…
Galactic or extragalactic chemical tagging for NGC3201? Discovery of an anomalous CN-CH relation
Bruno Dias, Ignacio Araya, João Paulo Nogueira-Cavalcante +2
(ABRIDGED) The origin of the globular cluster (GC) NGC3201 is under debate. Its retrograde orbit points to an extragalactic origin, but no further chemical evidence supports this i…
Stellar parameters and chemical abundances of 223 evolved stars with and without planets
E. Jofré, R. Petrucci, C. Saffe +5
We present fundamental stellar parameters and chemical abundances for a sample of 86 evolved stars with planets and for a control sample of 137 stars without planets. The analysis…
