NASA’s EPOXI mission used the Deep Impact spacecraft to observe the disk-integrated Earth as an analog to terrestial exoplanets’ appearance. The mission took five 24 hr observations in 2008–2009 at
Characterization of Exoplanet Atmospheres with the Optical Coronagraph on WFIRST
• Physics, Geology

WFIRST-CGI will obtain images and low-resolution spectra of a handful to a dozen extrasolar planets and protoplanetary disks. Its unprecedented contrast levels in the optical will provide
The Geometric Magnitude and Albedo for the Globe of Saturn
• Physics, Geology
• 2017
Saturn's geometric magnitude and albedo were determined by Mallama et al. (2017, Icarus 282, 19-33). That analysis depended largely on photometric data obtained when the ring system interfered with
Two Planets Straddling the Habitable Zone of the Nearby K Dwarf Gl 414A
• Physics, Geology
• 2020
We present the discovery of two planets orbiting the nearby (D = 11.9 pc) K7 dwarf Gl 414A. Gl 414A b is a sub-Neptune mass planet with M ⊕ and a semimajor axis of 0.23 ± 0.01 au. Gl 414A c is a
Temporal and spatial variations of the absolute reflectivity of Jupiter and Saturn from 0.38 to 1.7 $\mu$m with PlanetCam-UPV/EHU
• Physics, Geology
• 2017
We provide measurements of the absolute reflectivity of Jupiter and Saturn along their central meridians in filters covering a wide range of visible and near-infrared wavelengths (from 0.38 to 1.7
The Spherical Bolometric Albedo of Planet Mercury
Published reflectance data covering several different wavelength intervals has been combined and analyzed in order to determine the spherical bolometric albedo of Mercury. The resulting value of
Identifying Exo-Earth Candidates in Direct Imaging Data through Bayesian Classification
• Geology, Physics
The Astronomical Journal
• 2019
A Bayesian method is presented for estimating the likelihood that any directly imaged extrasolar planet is a true exo-Earth candidate by interpreting the planet's apparent magnitude and separation in light of existing exoplanet statistics.
The Mid-IR Albedo of Neptune Derived from Spitzer Observations
• Physics, Geology
• 2018
Mid-IR albedo values of Neptune are derived from Spitzer Space Telescope measurements reported by Stauffer et al. (2016). The method of this derivation is described and the results indicate that the
Method for deriving optical telescope performance specifications for Earth-detecting coronagraphs
• Physics
• 2020
A systems engineering process for deriving a wavefront stability error budget for any potential telescope/coronagraph combination is described and the utility of the method is demonstrated by intercomparing the ability of several monolithic and segmented telescope and coronagraph combinations to detect an exo-Earth at 10 pc.
