Testing Earth-like atmospheric evolution on exo-Earths through oxygen absorption: required sample sizes and the advantage of age-based target selection
Alex Bixel, Dániel Apai
Life has had a dramatic impact on the composition of Earth's atmosphere over time, which suggests that statistical studies of other inhabited planets' atmospheres could reveal how…
EDEN: Sensitivity Analysis and Transiting Planet Detection Limits for Nearby Late Red Dwarfs
Aidan Gibbs, Alex Bixel, Benjamin Rackham +23
Small planets are common around late-M dwarfs and can be detected through highly precise photometry by the transit method. Planets orbiting nearby stars are particularly important…
ACCESS: A Visual to Near-infrared Spectrum of the Hot Jupiter WASP-43b with Evidence of , but no evidence of Na or K
Ian C. Weaver, Mercedes López-Morales, Néstor Espinoza +11
We present a new ground-based visual transmission spectrum of the hot Jupiter WASP-43b, obtained as part of the ACCESS Survey. The spectrum was derived from four transits observed…
Identifying Exo-Earth Candidates in Direct Imaging Data through Bayesian Classification
Alex Bixel, Dániel Apai
Future space telescopes may be able to directly image 10 - 100 planets with sizes and orbits consistent with habitable surface conditions ("exo-Earth candidates" or EECs), bu…
A Thousand Earths: A Very Large Aperture, Ultralight Space Telescope Array for Atmospheric Biosignature Surveys
Daniel Apai, Tom D. Milster, Dae Wook Kim +4
An outstanding, multi-disciplinary goal of modern science is the study of the diversity of potentially Earth-like planets and the search for life in them. This goal requires a bold…
ACCESS: Ground-based Optical Transmission Spectroscopy of the Hot Jupiter WASP-4b
Alex Bixel, Benjamin V. Rackham, Dániel Apai +6
We present an optical transmission spectrum of the atmosphere of WASP-4b obtained through observations of four transits with Magellan/IMACS. Using a Bayesian approach to atmospheri…
