Detecting Earth-like Biosignatures on Rocky Exoplanets around Nearby Stars with Ground-based Extremely Large Telescopes

Mercedes López-Morales, Thayne Currie, Johanna Teske +21

As we begin to discover rocky planets in the habitable zone of nearby stars with missions like TESS and CHEOPS, we will need quick advancements on instrumentation and observational…

Constraining Stellar Photospheres as an Essential Step for Transmission Spectroscopy of Small Exoplanets

Benjamin V. Rackham, Arazi Pinhas, Dániel Apai +29

Transmission spectra probe the atmospheres of transiting exoplanets, but these observations are also subject to signals introduced by magnetic active regions on host stars. Here we…

A Statistical Comparative Planetology Approach to Maximize the Scientific Return of Future Exoplanet Characterization Efforts

Jade H. Checlair, Dorian S. Abbot, Robert J. Webber +37

Provided that sufficient resources are deployed, we can look forward to an extraordinary future in which we will characterize potentially habitable planets. Until now, we have had…

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…

The Transit Light Source Effect II: The Impact of Stellar Heterogeneity on Transmission Spectra of Planets Orbiting Broadly Sun-like Stars

Benjamin V. Rackham, Dániel Apai, Mark S. Giampapa

Transmission spectra probe exoplanetary atmospheres, but they can also be strongly affected by heterogeneities in host star photospheres through the transit light source effect. He…

ACCESS I: An Optical Transmission Spectrum of GJ 1214b Reveals a Heterogeneous Stellar Photosphere

Benjamin Rackham, Néstor Espinoza, Dániel Apai +8

GJ 1214b is the most studied sub-Neptune exoplanet to date. Recent measurements have shown its near-infrared transmission spectrum to be flat, pointing to a high-altitude opacity s…
