A study compares ~50,000 low-amplitude Kepler rotational variable stars to a previous high-amplitude sample from ASAS-SN, revealing differences in rotation rates, binarity, and star spot activity.

Why it matters: Understanding rotational variables helps probe stellar magnetism, binary systems, and stellar evolution.

The big picture: Kepler variables are mostly slow-rotating, single main sequence stars, unlike the rapidly rotating ASAS-SN sample.

Stunning stat: Kepler rotators show significantly lower binary fractions and star spot activity than ASAS-SN stars.

Quick takeaway: Different surveys reveal distinct populations of rotational variables, emphasizing the diversity of stellar rotation and magnetism.
