A search for diffuse bands in fullerene planetary nebulae: evidence of diffuse circumstellar bands
J. J. Diaz-Luis, D. A. Garcia-Hernandez, N. Kameswara Rao +2
Large fullerenes and fullerene-based molecules have been proposed as carriers of diffuse interstellar bands (DIBs). The recent detection of the most common fullerenes (C60 and C70)…
AGB stars in the LMC: evolution of dust in circumstellar envelopes
F. Dell'Agli, P. Ventura, R. Schneider +4
We calculated theoretical evolutionary sequences of asymptotic giant branch (AGB) stars, including formation and evolution of dust grains in their circumstellar envelope. By consid…
Tracking Advanced Planetary Systems with HARPS-N (TAPAS). I. A multiple planetary system around the red giant star TYC 1422-614-1
A. Niedzielski, E. Villaver, A. Wolszczan +7
Context. Stars that have evolved-off the Main Sequence are crucial in expanding the frontiers of knowledge on exoplanets toward higher stellar masses, and to constrain star-planet…
Tracing chemical evolution over the extent of the Milky Way's Disk with APOGEE Red Clump Stars
David L. Nidever, Jo Bovy, Jonathan C. Bird +40
We employ the first two years of data from the near-infrared, high-resolution SDSS-III/APOGEE spectroscopic survey to investigate the distribution of metallicity and alpha-element…
Chemical abundances in Galactic planetary nebulae with Spitzer spectra
D. A. Garcia-Hernandez, S. K. Gorny
We present new low-resolution (R~800) optical spectra of 22 Galactic PNe with Spitzer spectra. These data are combined with recent optical spectroscopic data available in the liter…
Circumstellar effects on the Rb abundances in O-rich AGB stars
O. Zamora, D. A. Garcia-Hernandez, B. Plez +1
For the first time we explore the circumstellar effects on the Rb (and Zr) abundance determination in O-rich asymptotic giant branch (AGB) stars by considering the presence of a ga…
