JWST observations of the Ring Nebula (NGC 6720): I. Imaging of the rings, globules, and arcs
R. Wesson, Mikako Matsuura, Albert A. Zijlstra +18
We present JWST images of the well-known planetary nebula NGC 6720 (the Ring Nebula), covering wavelengths from 1.6m to 25 m. The bright shell is strongly fragmented with som…
Chemical Evolution of Ytterbium in the Galactic Disk
M. Montelius, R. Forsberg, N. Ryde +8
Measuring the abundances of neutron-capture elements in Galactic disk stars is an important part of understanding key stellar and galactic processes. In the optical wavelength regi…
A Near-infrared Survey of UV-excited Molecular Hydrogen in Photodissociation Regions
Kyle F. Kaplan, Harriet L. Dinerstein, Hwihyun Kim +1
We present a comparative study of the near-infrared (NIR) H line emission from five regions near hot young stars: Sharpless 140, NGC 2023, IC 63, the Horsehead Nebula, and the…
The IGRINS YSO Survey I. Stellar parameters of pre-main sequence stars in Taurus-Auriga
Ricardo López-Valdivia, Kimberly R. Sokal, Gregory N. Mace +19
We present fundamental parameters for 110 canonical K- & M-type (1.30.13) Taurus-Auriga young stellar objects (YSOs). The analysis produces a simultaneous determination…
Chemical Compositions of Red Giant Stars from Habitable Zone Planet Finder Spectroscopy
Christopher Sneden, Melike Afsar, Zeynep Bozkurt +15
We have used the Habitable Zone Planet Finder (HPF) to gather high resolution, high signal-to-noise near-infrared spectra of 13 field red horizontal-branch (RHB) stars, one open-cl…
Fluorine in the solar neighbourhood: the need for several cosmic sources
Nils Ryde, Henrik Jönsson, Gregory Mace +14
The cosmic origin of fluorine is still not well constrained. Several nucleosynthetic channels at different phases of stellar evolution have been suggested, but these must be constr…
