Investigating Phosphorus Abundances in a Sample of APOGEE-2 Bulge Globular Clusters
Beatriz Barbuy, José G. Fernández-Trincado, Morgan S. Camargo +9
Phosphorus enhanced (P-rich; [P/Fe] > 0.8) giants have been found among mildly metal-poor fiels stars, but in only one star in a globular cluster (GC), M4 (NGC 6121). Also, in a sa…
Deep survey of millimeter RRLs towards the planetary nebulae IC 418 and NGC 7027
Teresa Huertas-Roldán, Javier Alcolea, D. Aníbal García-Hernández +7
The circumstellar environments of PNe are wonderful chemically rich astrophysical laboratories in which the ionization of atoms and the formation of simple and complex molecules ca…
Planetary Nebulae of the Large Magellanic Cloud II: the connection with the progenitors' properties
P. Ventura, S. Tosi, D. A. García-Hernández +6
The study of planetary nebulae (PNe) offers the opportunity of evaluating the efficiency of the dust production mechanism during the very late asymptotic giant branch (AGB) phases.…
Unveiling the chemical fingerprint of phosphorus-rich stars II. Heavy-element abundances from UVES/VLT spectra
Maren Brauner, Marco Pignatari, Thomas Masseron +2
The atmospheres of phosphorus-rich stars have been shown to contain between 10 and 100 times more P than our Sun. Given its crucial role as an essential element for life, it is esp…
Carbon enrichment in APOGEE disk stars as evidence of mass transfer in binaries
Steve Foster, Ricardo P. Schiavon, Denise B. de Castro +10
Carbon abundances in first-ascent giant stars are usually lower than those of their main-sequence counterparts. At moderate metallicities, stellar evolution of single stars cannot…
Planetary Nebulae of the Large Magellanic Cloud I: A multiwavelength analysis
Silvia Tosi, Flavia Dell'Agli, Devika Kamath +5
Planetary nebulae (PNe) have three main components: a central star (CS), ionised gas and dust in the nebula. Each of them contains critical chemical fingerprints of their evolution…
The first measurements of carbon isotopic ratios in post-RGB stars: SZ Mon and DF Cyg. E-iSpec: A spectral analysis tool to derive elemental abundances and isotopic ratios for evolved stars
Maksym Mohorian, Devika Kamath, Meghna Menon +4
Dusty post-red giant branch (post-RGB) stars are low- and intermediate-mass stars where the RGB evolution was prematurely terminated by a poorly understood binary interaction. Thes…
Heavy-element yields and abundances of Asymptotic Giant Branch models with a Small Magellanic Cloud metallicity
Amanda Karakas, Maria Lugaro, Marília Carlos +3
We present new theoretical stellar yields and surface abundances for asymptotic giant branch (AGB) models with a metallicity appropriate for stars in the Small Magellanic Cloud (SM…
Planetary Nebulae in the Small Magellanic Cloud
P. Ventura, L. Stanghellini, M. Di Criscienzo +2
We analyse the planetary nebulae (PNe) population of the Small Magellanic Cloud (SMC), based on evolutionary models of stars with metallicities in the range $10^{-3} \leq Z \leq 4\…
