  "summary": "Toward the end of their lives, low-mass stars undergo an abrupt dip in brightness, also known as the luminosity bump. While the endpoint of this bump is well understood, its onset has remained elusive. Now, in a paper published by The Astrophysical Journal Letters, Saskia Hekker, leader of the Theory and Observations of Stars group at the Heidelberg Institute for Theoretical Studies (HITS), finds…",
