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…
High-resolution near-IR Spectral mapping with H and [Fe II] lines of Multiple Outflows around LkH 234
Heeyoung Oh, Tae-Soo Pyo, Bon-Chul Koo +11
We present a high-resolution, near-IR spectroscopic study of multiple outflows in the LkH 234 star formation region using the Immersion GRating INfrared Spectrometer (IGRINS). S…
Excitation of Molecular Hydrogen in the Orion Bar Photodissociation Region From a Deep Near-Infrared IGRINS Spectrum
Kyle F. Kaplan, Harriet L. Dinerstein, Heeyoung Oh +9
We present a deep near-infrared spectrum of the Orion Bar Photodissociation Region (PDR) taken with the Immersion Grating INfrared Spectrometer (IGRINS) on the 2.7 m telescope at t…
The Prevalence and Impact of Wolf-Rayet Stars in Emerging Massive Star Clusters
Kimberly R. Sokal, Kelsey E. Johnson, Remy Indebetouw +1
We investigate Wolf-Rayet (WR) stars as a source of feedback contributing to the removal of natal material in the early evolution of massive star clusters. Despite previous work su…
The importance of Wolf-Rayet ionization and feedback on super star cluster evolution
Kimberly R. Sokal, Kelsey E. Johnson, Philip Massey +1
The feedback from massive stars is important to super star cluster (SSC) evolution and the timescales on which it occurs. SSCs form embedded in thick material, and eventually, the…
An Emerging Wolf-Rayet Massive Star Cluster in NGC 4449
Kimberly R. Sokal, Kelsey E. Johnson, Rémy Indebetouw +1
We present a panchromatic investigation of the partially-embedded, emerging massive cluster Source 26 (= S26) in NGC 4449 with optical spectra obtained at Apache Point Observatory…
