Radiation-driven acceleration in the expanding WR140 dust shell
Yinuo Han, Peter G. Tuthill, Ryan M. Lau +1
The Wolf-Rayet (WR) binary system WR140 is a close (0.9-16.7 mas) binary star consisting of an O5 primary and WC7 companion and is known as the archetype of episodic dust-producing…
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…
A massive AGB donor in Scutum X-1: Identification of the first Mira variable in an X-ray binary
Kishalay De, Deepto Chakrabarty, Roberto Soria +9
The symbiotic X-ray binary Sct X-1 was suggested as the first known neutron star accreting from a red supergiant companion. Although known for nearly 50 years, detailed characteriz…
Outbursting Young Stellar Object PGIR 20dci in the Perseus Arm
Lynne A. Hillenbrand, Kishalay De, Matthew Hankins +9
We report the discovery of a likely outbursting Class I young stellar object, associated with the star-forming region NGC 281-W (distance kpc). The source is currently s…
AT 2019qyl in NGC 300: Internal Collisions in the Early Outflow from a Very Fast Nova in a Symbiotic Binary
Jacob E. Jencson, Jennifer E. Andrews, Howard E. Bond +39
Nova eruptions, thermonuclear explosions on the surfaces of white dwarfs (WDs), are now recognized to be among the most common shock-powered astrophysical transients. We present th…
