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…
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…
Morpho-kinematic modeling of the expanding ejecta of the extremely slow nova V1280 Scorpii
Hiroyuki Naito, Akito Tajitsu, Valèrio A. R. M. Ribeiro +10
Morphology of nova ejecta is essential for fully understanding the physical processes involved in nova eruptions. We studied the 3D morphology of the expanding ejecta of the extrem…
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…
Revisiting the Impact of Dust Production from Carbon-Rich Wolf-Rayet Binaries
Ryan M. Lau, J. J. Eldridge, Matthew J. Hankins +3
We present a dust spectral energy distribution (SED) and binary stellar population analysis revisiting the dust production rates (DPRs) in the winds of carbon-rich Wolf-Rayet (WC)…
AKARI/IRC Near-Infrared Spectral Atlas of Galactic Planetary Nebulae
Ryou Ohsawa, Takashi Onaka, Itsuki Sakon +2
Near-infrared (2.5-5.0m) low-resolution () spectra of 72 Galactic planetary nebulae (PNe) were obtained with the Infrared Camera (IRC) in the post-helium phase.…
