pyEDITH: the coronagraphic exposure time calculator for the Habitable Worlds Observatory
Eleonora Alei, Miles H. Currie, Corey Spohn +7
To support the development of next-generation missions for the search and characterization of habitable planets, high-fidelity tools for astrophysical and instrumental noise simula…
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…
Exozodiacal dust as a limitation to exoplanet imaging and spectroscopy
Miles H. Currie, John Debes, Yasuhiro Hasegawa +7
In addition to planets and other small bodies, stellar systems will likely also host exozodiacal dust, or exozodi. This warm dust primarily resides in or near the habitable zone of…
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…
