SPIRITS 19q: Dust Production by a Subsolar-metallicity Carbon-rich Wolf-Rayet Star in NGC 2403
Sam Rose, Ryan M. Lau, Jacob E. Jencson +20
We present JWST/NIRSpec IFU observations of SPIRITS 19q, the highly dust-producing carbon-rich (WC) binary candidate located in a subsolar-metallicity region of the nearby spiral g…
The long-period spectroscopic orbit and dust creation in the Wolf-Rayet binary system WR 125
Noel D. Richardson, Andrea R. Daly, Peredur M. Williams +8
Several long-period binaries with a carbon-rich Wolf-Rayet star and an O star produce dust in their wind collisions. In eccentric binaries, this is seen most strongly near periastr…
From Dust to Nanodust: Resolving Circumstellar Dust from the Colliding-Wind Binary Wolf-Rayet (WR) 140
Ryan M. Lau, Jason Wang, Matthew J. Hankins +17
Wolf-Rayet (WR) 140 is the archetypal periodic dust-forming colliding-wind binary that hosts a carbon-rich WR (WC) star and an O-star companion with an orbital period of 7.93 years…
Nested Dust Shells around the Wolf-Rayet Binary WR 140 observed with JWST
Ryan M. Lau, Matthew J. Hankins, Yinuo Han +29
Massive colliding-wind binaries that host a Wolf-Rayet (WR) star present a potentially important source of dust and chemical enrichment in the interstellar medium (ISM). However, t…
Detection of a broad 8 m UIR feature in the mid-infrared spectrum of WR 125 observed with Subaru/COMICS
Izumi Endo, Ryan M. Lau, Itsuki Sakon +3
We present the detection of a broad 8 m feature in newly formed dust around the carbon-rich Wolf-Rayet (WC) binary WR 125 from N-band low-resolution (NL; R250) spectroscop…
Theoretical study of infrared spectra of interstellar PAH molecules with N, NH & NH incorporation
Akant Vats, Amit Pathak, Takashi Onaka +3
This work presents theoretical calculations of infrared spectra of nitrogen (N)-containing polycyclic aromatic hydrocarbon (PAH) molecules with incorporation of N, NH and NH us…
Resolving Decades of Periodic Spirals from the Wolf-Rayet Dust Factory WR 112
Ryan M. Lau, Matthew J. Hankins, Yinuo Han +9
WR 112 is a dust-forming carbon-rich Wolf-Rayet (WC) binary with a dusty circumstellar nebula that exhibits a complex asymmetric morphology, which traces the orbital motion and dus…
