Near-infrared spectroscopy of a massive young stellar object in the direction toward the Galactic Center: XCN and aromatic C-D features
Takashi Onaka, Itsuki Sakon, Takashi Shimonishi
We report near-infrared (2.5--5 micron) long-slit (~ 30 arcsec) spectroscopy of a young stellar object in the direction toward the Galactic center with the Infrared Camera on board…
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…
Laboratory measurements of stretching band strengths of deuterated Quenched Carbonaceous Composites (D-QCC)
Tamami Mori, Takashi Onaka, Itsuki Sakon +4
The observed large variation in the abundance of deuterium (D) in the interstellar medium (ISM) suggests that a significant fraction of D may be depleted into polycyclic aromatic h…
