Primordial Black Hole Flybys Could Alter Exoplanet Orbits

Close encounters with massive objects can alter the orbits of planets around their stars. Stellar flybys can change planetary orbits, and may be responsible for some of the rogue or free-floating planets astronomers have discovered. But stars aren't the only massive objects out there, and new research suggests that primordial black holes may alter the orbits of exoplanets.

Black Hole Mergers Open Doors For Students - UMBC: University Of Maryland, Baltimore County

There are black holes, and then there are supermassive black holes (SBMH), with masses millions to billions of times as great as the Sun. A small percentage of SBMH are furiously gobbling up matter; these are called active galactic nuclei (AGN). Adi Foord, assistant professor of physics, is co-leading a research project designed to further understanding of how this rare type of black hole forms and changes over time.  The project, recently funde…
