Combining Photometry and Astrometry to Improve Orbit Retrieval of Directly Imaged Exoplanets
Margaret Bruna, Nicolas B. Cowan, Julia Sheffler +3
Future missions like Roman, HabEx, and LUVOIR will directly image exoplanets in reflected light. While current near infrared direct imaging searches are only sensitive to young, se…
exocartographer: A Bayesian Framework for Mapping Exoplanets in Reflected Light
Ben Farr, Will M. Farr, Nicolas B. Cowan +2
Future space telescopes will directly image extrasolar planets at visible wavelengths. Time-resolved reflected light from an exoplanet encodes information about atmospheric and sur…
Analytic Reflected Lightcurves for Exoplanets
Hal M. Haggard, Nicolas B. Cowan
The disk-integrated reflected brightness of an exoplanet changes as a function of time due to orbital and rotational motion coupled with an inhomogeneous albedo map. We have previo…
Odd Harmonics in Exoplanet Photometry: Weather or Artifact?
Nicolas B. Cowan, Victoria Chayes, Elie Bouffard +2
Photometry of short-period planetary systems allows astronomers to monitor exoplanets, their host stars, and their mutual interactions. In addition to the transits of a planet in f…
Inferring Planetary Obliquity Using Rotational & Orbital Photometry
Joel C. Schwartz, Clara Sekowski, Hal M. Haggard +2
The obliquity of a terrestrial planet is an important clue about its formation and critical to its climate. Previous studies using simulated photometry of Earth show that continuou…
Lightcurves of Stars & Exoplanets: Estimating Inclination, Obliquity, and Albedo
Nicolas B. Cowan, Pablo A. Fuentes, Hal M. Haggard
[Abridged] Distant stars and planets will remain spatially unresolved for the foreseeable future. It is nonetheless possible to infer aspects of their brightness markings and viewi…
