Amery Gration @amerygration.bsky.social · 17/02/2026Software paper! This is Dyad, a Python library for binary-star dynamics and statistics. It allows you to generate a population of binary stars by sampling their component masses and orbital elements from a library of choices.

Amery Gration @amerygration.bsky.social · 12/02/2026New paper 👀! The statistics of binary-star masses relies on the joint mass function, which must respect the IMF of the binaries' components and the distribution of their mass ratios. @robizzard.bsky.social, @payeldas.bsky.social, and I show how to construct it in the general case. 🔭☄️arxiv.orgA method for constructing the joint mass function of binary starsThe initial mass function (IMF) describes the distribution of stellar masses in a population of newly born stars and is amongst the most fundamental concepts in astrophysics. It is not only the direct... 010

Trawling has only been filmed underwater a few times in documentary history, and never with such clarity. What’s so heart-rending about these shots is watching how the animals don’t just get swept up — they swim for their lives. 🌎🦑🧪 8719901285
