Preparing for the Early eVolution Explorer: Detecting the Primordial, Transiting Exoplanet Population
The close-in small planet population may be formed either with hydrogen/helium dominated envelopes or with water-rich interiors. Both scenarios reproduce the present day planet population in mass, radius, and periods, […]

TESS Discovers a Second System of Transiting Exocomets in the Extreme Debris Disk of RZ Psc
We present the TESS discovery of only the second system of transiting exocomets with a sufficient number of events to measure the size distribution in the RZ Psc system, enabling […]

Preparing For The Early eVolution Explorer
Ultraviolet flare emission can drive photochemistry in exoplanet atmospheres and even serve as the primary source of uncertainty in atmospheric retrievals. Additionally, flare energy budgets are not well-understood due to […]
