Who doesn't love a little bit of Betelgeuse related news? In episode, I dove into some of the work to study this stars little companion 🔭🧪☄️
Michelle's first paper focuses on her all time favourite star, Betelgeuse! Recent work has shown that it likely has a little companion orbiting it, and this paper searches for (and finds) evidence of its wake! 🔭☄️ arxiv.org/abs/2601.00470

Color isn’t real the way you think it is.
It’s a private hallucination your brain creates from three cleverly overlapping sensors in your eyes.
The author explains it so cleanly it hurts (in a good way).

Thread 🧵
An object's appearance starts with which wavelengths it reflects/absorbs under the incoming light.
But the key insight from author's piece (and vision science in general) is that color isn't 'in' the object or even 'in' the light spectrum itself.

It's about NGC 2736, or Pencil Nebula, a small part of the Vela Supernova Remnant. 🔭
It's thought to be formed from part of its shock wave, plowing through interstellar space at over 500,000 km per hour!

An interesting way to disentangle signal from astronomical time series data including red noise. In its core weighted-wavelet transformations (drop->droplet, wave->wavele).
Recently published in JOSS: the QhX allows for periodicity detection in the presence of red noise, use cases include QSOs and earthquakes among others. #astrocode

Astronomers surprised by mysterious shock wave around dead star 😲
No known mechanism can fully explain our VLT's observations of the type of shock wave — called a bow shock — that a white dwarf originates as it interacts with the interstellar gas.

Take off to the bright orange star Betelgeuse 🚀🌟
The star underwent an unprecedented dimming in late 2019 and early 2020. Observations later revealed that it was caused by a dusty veil shading the star, due to a drop in temperature on the star's surface.
