The exozodi spectral effect: Residual habitable zone dust may bias exoEarth characterization
Miles H. Currie, Christopher C. Stark, Eleonora Alei +1
All exoplanetary systems are expected to host exozodiacal dust, or exozodi, originating from planetesimals. For many stars, exozodi will likely be the largest source of astrophysic…
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-…
The Third Option: Color Phase Curves to Characterize the Atmospheres of Temperate Rocky Exoplanets
Drake Deming, Andrew Lincowski, Laura Kreidberg +6
Detecting and characterizing the atmospheres of rocky exoplanets has proven to be challenging for JWST. Transit spectroscopy of the TRAPPIST-1 planets has been impacted by the effe…
Minimizing Star Spot Contamination of Exoplanet Transit Spectroscopy Using Alternate Normalization
Drake Deming, Miles H. Currie, Victoria S. Meadows +1
Recently, Currie et al. simulated the detection of molecules in the atmospheres of temperate rocky exoplanets transiting nearby M-dwarf stars. They simulated detections via spectra…
There's more to life in reflected light: Simulating the detectability of a range of molecules for high-contrast, high-resolution observations of non-transiting terrestrial exoplanets
Miles H. Currie, Victoria S. Meadows
The upcoming extremely large telescopes will provide the first opportunity to search for signs of habitability and life on non-transiting terrestrial exoplanets using high-contrast…
