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…
An infrared census of R Coronae Borealis Stars II -- Spectroscopic classifications and implications for the rate of low-mass white dwarf mergers
Viraj R. Karambelkar, Mansi M. Kasliwal, Patrick Tisserand +18
We present results from a systematic infrared (IR) census of R Coronae Borealis (RCB) stars in the Milky Way, using data from the Palomar Gattini IR (PGIR) survey. R Coronae Boreal…
The interacting double white dwarf population with LISA; stochastic foreground and resolved sources
Alexandre Toubiana, Nikolaos Karnesis, Astrid Lamberts +1
In this work, we investigate the impact of tidal torques and mass transfer on the population of double white dwarfs (DWDs) that will be observed with LISA. Starting from a distribu…
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…
Smoke on the wind: dust nucleation in archetype colliding wind pinwheel WR104
A. Soulain, A. Lamberts, F. Millour +2
A handful of binary Wolf-Rayet stars are known to harbour spectacular spiral structures spanning a few hundred AU. These systems host some of the highest dust production rates in t…
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)…
