(Sub-)stellar variability: from 20 M$_{\odot}$ to 13 M$_{\rm Jup}$

TL;DR

This paper reviews stellar and sub-stellar photometric variability across a wide mass range, highlighting key discoveries and encouraging amateur contributions to ongoing research.

Contribution

It provides a summary of previous studies on variability in stars and brown dwarfs and discusses how amateurs can assist professional astronomers.

Findings

Discovered the most variable brown dwarf in the sky

Reviewed variability in massive stars and brown dwarfs

Encouraged amateur participation in variability studies

Abstract

Massive early-type stars vary; low-mass late-type brown dwarfs vary, too. I will make a short, but illustrative, summary of my previous studies on stellar and sub-stellar photometric variability (including the discovery of the most variable brown dwarf in the whole sky), and explain how amateurs can help professional astronomers with our investigations.
