Multi-bandpass Photometry for Exoplanet Atmosphere Reconnaissance (MPEAR) with the Habitable Worlds Observatory (HWO) -- I. Differentiating Earth from Neptunes During Discovery
Eleonora Alei, Avi M. Mandell, Miles H. Currie +7
As the architecture for the Habitable Worlds Observatory (HWO) is being developed, it is crucial to optimize the observing strategies for a survey to detect and characterize Earth-…

A comprehensive spectroscopic reference of the solar system and its application to exoplanet direct imaging
Allison Payne, Geronimo L. Villanueva, Vincent Kofman +5
We present a calibrated database of reflectance spectra for the solar system planets (i.e., Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune) and for Titan, spanning f…

The pale blue dot: using the Planetary Spectrum Generator to simulate signals from hyper realistic exo-Earths
Vincent Kofman, Geronimo Villanueva, Thomas Fauchez +5
The atmospheres and surfaces of planets show tremendous amount of spatial variation, which has a direct effect on the spectrum of the object, even if this may not be spatially reso…
