Astronomers find a small gap in HR diagram
Researcher Wei-Chun Jao has just published an article to the Astrophysical Journal Letters showing the discovery of a small gap within the Hertzsprung-Russell diagram based on Gaia Data Release 2. This narrow gap (approximately 0.05 mag wide) is near the regime in which the interiors of M dwarfs transition from being partially convective to fully convective. This gap is suggested to be linked to this transition in M dwarfs. The research highlights can be found here.
