A previously unexplained branch of cooling white dwarfs is likely a traffic jam caused by an 8 billion year delay in cooling. A heavy isotope of neon settling down into the core of the star could be the source.
In mid August 600 astronomers met in Reykjavik, Iceland Extreme Solar Systems IV.
The absence of dusty circumplanetary disks around young giant planets suggests moonetesimals grow relatively quickly.
Just over a week ago astronomers from all over the United States submitted white papers to the Astro2020 decadal survey on topics across the field of astronomy. They are great short summaries of topics from planetary systems to galaxy evolution to multi-messenger astronomy and everything in-between.
What does a disk around a binary star look like? One possibility, recently observed around a young star for the first time, is that it is flipped on its side—its rotation is perpendicular to the orbit of the binary system!
