Astronomers thought “hot Jupiter” exoplanets formed far from their stars before migrating inwards to an ultra-close orbit. Today’s paper challenges that assumption, presenting evidence that one hot Jupiter formed close to its star.

This guest post was written by Aylin Garcia Soto, a graduating Ph.D. student from Dartmouth University studying M dwarf variability. She will start a postdoc at Boise State University working with Dr. Brian Jackson on tidal decay in exostellar systems. Outside of research, she enjoys reading, watching K dramas (and other dramas), playing guitar, and writing creative stories. Title: Exploring the Active Galactic Nucleus Fraction of a Sample of JWST’s Little Red Dots at 4 < z < 8: Overmassive Black Holes Are Strong Flavored Authors: Emmanuel Durodola, Fabio Pacucci, Ryan C. Hickox First Author’s Institution: Department of Physics & Astronomy, Dartmouth College, Hanover, NH 03755, USA Status: Published in ApJ [open access] The Little Red Dot Once upon a time there was an object called Little Red Dot. It lived a long long long (over 12 billion years) ago with a big big big (x10) ol’ black hole wrapped in a large dusty blanket. One day, a gentle-telescope named JWST took its camera to visit its universe, and on its way, it bumped into Little Red. Oh my, what a red, old, compact galaxy you are. All the better to confuse you with, my dear scientist. What strange spectral energy distribution you present. All the better to keep you guessing (what I am). The Little Red Dots and Modern AGNs Much of what we know about Little Red Dots (LRDs) arose after 2024 thanks to data from the JWST space telescope. These red objects represent emitted light from high-redshift or distant objects that formed about 1.5 billion years after the big-bang (13.8 billion years ago). To measure the...
