Constraining properties of dust formed in Wolf-Rayet binary WR 112 using mid-infrared and millimeter observations
Donglin Wu, Yinuo Han, Peredur M. Williams +9
Binaries that host a carbon-rich Wolf-Rayet (WC) star and an OB-type companion can be copious dust producers. Yet the properties of dust, particularly the grain size distribution,…
The Serpent Eating Its Own Tail: Dust Destruction in the Apep Colliding-Wind Nebula
Ryan M. T. White, Benjamin J. S. Pope, Peter G. Tuthill +5
Much of the carbonaceous dust observed in the early universe may originate from colliding wind binaries (CWBs) hosting hot, luminous Wolf-Rayet (WR) stars. Downstream of the shock…
The formation and evolution of dust in the colliding-wind binary Apep revealed by JWST
Yinuo Han, Ryan M. T. White, Joseph R. Callingham +4
Carbon-rich Wolf-Rayet (WR) stars are significant contributors of carbonaceous dust to the galactic environment, however the mechanisms and conditions for formation and subsequent…
Carbon-rich dust injected into the interstellar medium by Galactic WC binaries survives for hundreds of years
Noel D. Richardson, Micaela Henson, Emma P. Lieb +23
Some carbon-rich Wolf-Rayet stars (WC stars) show an infrared excess from dust emission. Dust forms in the collision of the WC wind with a companion star's wind. As this dust is ca…
A General, Differentiable Transit Model for Ellipsoidal Occulters: Derivation, Application, and Forecast of Planetary Oblateness and Obliquity Constraints with JWST
Shashank Dholakia, Shishir Dholakia, Benjamin J. S. Pope
Increasingly precise space-based photometry uncovers higher-order effects in transits, eclipses and phase curves which can be used to characterize exoplanets in novel ways. The sub…
Astrometry and Precise Radial Velocities Yield a Complete Orbital Solution for the Nearby Eccentric Brown Dwarf LHS 1610 b
Evan Fitzmaurice, Gudmundur Stefánsson, Robert D. Kavanagh +18
The LHS 1610 system consists of a nearby ( pc) M5 dwarf hosting a candidate brown dwarf companion in a day, eccentric () orbit. We confirm this brown dwa…
Low-frequency monitoring of flare star binary CR Draconis: Long-term electron-cyclotron maser emission
J. R. Callingham, B. J. S. Pope, A. D. Feinstein +12
Recently detected coherent low-frequency radio emission from M dwarf systems shares phenomenological similarities with emission produced by magnetospheric processes from the gas gi…
The extreme colliding-wind system Apep: resolved imagery of the central binary and dust plume in the infrared
Y. Han, P. G. Tuthill, R. M. Lau +6
The recent discovery of a spectacular dust plume in the system 2XMM J160050.7-514245 (referred to as "Apep") suggested a physical origin in a colliding-wind binary by way of the "P…
Coherent radio emission from a quiescent red dwarf indicative of star-planet interaction
H. K. Vedantham, J. R. Callingham, T. W. Shimwell +11
Low frequency (MHz) stellar radio emission is expected to originate in the outer corona at heights comparable to and larger than the stellar radius. Such emission…
