Context. 55 Cnc e is an ultra-short period super-Earth transiting a Sun-like star. Previous
observations in the optical range detected a time-variable flux modulation that is phased …

Abstract T​​​​​​ he enigmatic nature of 55 Cancri e has defied theoretical explanation.
Any explanation needs to account for the observed variability of its secondary eclipse depth …

Context. The nature of the close-in rocky planet 55 Cnce is puzzling, despite it having been
observed extensively. Its optical and infrared occultation depths show temporal variability, in …

Close-in lava planets represent an extreme example of terrestrial worlds, but their high
temperatures may allow us to probe a diversity of crustal compositions. The brightest and …

The ultra-short-period super-Earth 55 Cancri e has a measured radius of 1.88 Earth radii.
Previous thermal phase curve observations suggest a strong temperature contrast between …

Context. Multiwavelength photometry of the secondary eclipses of extrasolar planets is able
to disentangle the reflected and thermally emitted light radiated from the planetary dayside …

Planets with orbital periods shorter than 1 day are rare and have formation histories that are
not completely understood. Small (R p< 2 R⊕) ultra-short-period (USP) planets are highly …

Characterizing rocky exoplanets is a central endeavor of astronomy, and yet the search for
atmospheres on rocky exoplanets has hitherto resulted in either tight upper limits on the …

In the last few years astronomical surveys have expanded the reach of planetary science
into the realm of small and dense extrasolar worlds. These share a number of characteristics …

Context. Ultra-hot Jupiters present a unique opportunity to understand the physics and
chemistry of planets, their atmospheres, and interiors at extreme conditions. WASP-12 b …
