An Investigation of Non-Canonical Mixing in Red Giant Stars Using APOGEE 12C/13C Ratios Observed in Open Cluster Stars
Caroline McCormick, Steven R. Majewski, Verne V. Smith +9
Standard stellar evolution theory poorly predicts the surface abundances of chemical species in low-mass, red giant branch (RGB) stars. Observations show an enhancement of p-p chai…
The carbon star DY Persei may be a cool R Coronae Borealis variable
D. A. Garcia-Hernandez, N. Kameswara Rao, D. L. Lambert +3
Optical and near-IR photometry suggests that the carbon star DY Persei exhibits fadings similar to those of R Coronae Borealis (RCB) variables. Photometric surveys of the Galaxy an…
The messy death of a multiple star system and the resulting planetary nebula as observed by JWST
Orsola De Marco, Muhammad Akashi, Stavros Akras +66
Planetary nebulae (PNe), the ejected envelopes of red giant stars, provide us with a history of the last, mass-losing phases of 90 percent of stars initially more massive than the…
On the presence of metallofullerenes in fullerene-rich circumstellar envelopes
R. Barzaga, D. A. Garcia-Hernandez, S. Diaz-Tendero +3
The presence of neutral C60 fullerenes in circumstellar environments has been firmly established by astronomical observations as well as laboratory experiments and quantum-chemistr…
Is Terzan 5 the remnant of a building block of the Galactic bulge? Evidence from APOGEE
Dominic J. Taylor, Andrew C. Mason, Ricardo P. Schiavon +16
It has been proposed that the globular cluster-like system Terzan 5 is the surviving remnant of a primordial building block of the Milky Way bulge, mainly due to the age/metallicit…
Carbon Abundances in Compact Galactic Planetary Nebulae: An Ultraviolet spectroscopic study with the Space Telescope Imaging Spectrograph (STIS)
Letizia Stanghellini, Rafia Bushra, Richard A. Shaw +3
We surveyed a sample of compact Galactic planetary nebulae (PNe) with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope (HST/STIS) to determine their gas-phase…
