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.
The spectroscopists don’t want you to know that exoplanet atmospheres are actually three-dimensional! Today’s authors use computational climate models to study how we might be able to directly observe different planetary heating processes.

Astronomers still aren’t completely certain how Hot Jupiters form. Today’s paper presents a population level study that suggests HJs form far away from their host star, and are herded inwards by dynamical interactions with coplanar outer giant companions.
A new study finds that Hot Jupiters have companion planets in the system at a higher rate than previously thought. This has big implications for the theories on how these fascinating planets, and their larger systems, form.
