Index of every edition
This is the index for astro-ph Nightly. Every nightly edition is listed below, newest first — pick a date to read that night’s papers, explained at three levels.
An archive of 27 nightly editions of the arXiv astro-ph listing, from 1 October 2026 to 10 November 2026. Each edition sorts that night’s abstracts by field and explains every paper three ways: for astronomers, for the public and for young explorers.

Stars can have smaller companions going around them. Scientists studied lots of stars and found that companions of one particular relative size are hard to find: ones about two hundredths as heavy as their star. This pattern showed up around both smaller and bigger stars. The scientists think companions on either side of this gap might be made in different ways, but that part is not yet certain.
