A Search for Substellar Companions around A-type Stars: Pulsation Timing Detection of Eight Brown Dwarf Candidates and a Possible Habitable-zone Planet

Substellar companions are most often studied around solar-like or smaller stars, as the rapid rotation and variability of massive stars impede detection using traditional methods. An alternative technique, pulsation timing, uses photometry to measure light-travel-time variations—the time integral of the radial velocity...
