Whether you are already a fan of Greek mythology or someone who only vaguely remembers Icarus from a long-forgotten school lesson, today’s Astrobite will show you that flying too close to the Sun (and its consequences) is more than a myth when it comes to extremely hot exoplanets.
We cannot travel back in time, but we can still try to reconstruct how planets evolved from the clues they leave behind today. In this Astrobite, we explore how L 98-59 d’s atmosphere and interior models reveal a molten world still being reshaped by its host star.
We follow recipes for perfect cocktails, but we have yet to discover the recipe for sub-Neptune exoplanets. Today’s bite explores how hydrogen and silicates mix inside these mysterious worlds and what this tells us about their structure and evolution.
We use bottles, and sometimes a Brita, but how do planets store their water? The authors of today’s paper made a model to find out, and to evaluate whether certain planets are good at hanging on to their water or not.
Turns out there’s more than one way to “plate” a planet!
In this exciting new paper, our authors show that in quasars, X-ray coronas fueled by energy stolen from the accretion disk around the black hole may be responsible for the interesting ultraviolet and optical emission we see!
