If we don’t understand starspots, we won’t understand exoplanet atmospheres.
Lightning on Exoplanets
Besides our Earth, lightning has also been observed on Jupiter and Saturn, identified by the optical flash or the radio signal. In today’s bite, the authors take an even further step. They analyze whether lightning can explain the mysterious radio signals from the exoplanet HAT-P-11b.
A new discovery of a secondary eclipse
HAT-P-11b is a Neptune-size transiting exoplanet with water in its atmosphere. Here we discuss the first detection of its secondary eclipse.
Can planets and stars spin in unison?
