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, in these systems remain uncertain. We present Band 6 observations of WR 112 by the Atacama Large Millimeter/submillimeter Array telescope (ALMA), which are the first millimeter observations of a WC binary system capable of resolving its dust emission. By combining ALMA observations with James Webb Space Telescope (JWST) images, we were able to analyze the spatially resolved spectral energy distribution (SED) of WR 112. We found that the SEDs are consistent with emissions from hydrogen-poor amorphous carbon grains. Notably, our results also suggest that the majority of grains in the system have radii below one micrometer, and the extended dust structures are dominated by nanometer-sized grains. Among four parameterizations of the grain radius distribution that we tested, a bimodal distribution, with abundant nanometer-sized grains and a secondary population of 0.1-micron grains, best reproduces the observed SED. This bimodal distribution helps to reconcile the previously conflicting grain size estimates reported for WR 112 and for other WC systems. We hypothesize that dust destruction mechanisms such as radiative torque disruption and radiative-driven sublimation are responsible for driving the system to the bimodal grain size distribution.
I think we can all at least agree, that the Solar System is non-binary.
Estimates for binary stars in the Milky Way vary, but many sources suggest that roughly 50% to 85% of all stars are in binary or multiple-star systems.
Multiple star systems sound interesting, hmm, but the point is! Our Solar System is non-binary 🚥

Oh. It's brightening..!? This is within normal ranges for it, however. Guess we'll see...
(Still dim, but it was magnitude 11.1 a week or two ago. Fingers crossed 🤞)

"However, that assumes the long pulsation cycle is internal. If it’s actually due to a second star, then Betelgeuse is likely still fusing helium in its core, which means it has a lot longer left to go before it detonates, over a hundred thousand years. If you’re waiting for it to explode, and this second star turns out to be real, well then you’d better pack a lunch. It’ll be a while."

Around the world, professional and amateur astronomers alike are closely watching T Coronae Borealis – the “Blaze Star,” a binary system some 3,000 light-years from Earth – waiting for an impending nova explosion event so bright it will be visible on Earth with the naked eye.
