Orbit Refinement of WASP-18 b and Evidence Against the Existence of WASP-18 c
Avinash Salguneswaran Nediyedath, Kyle A. Pearson, Tara Fetherolf +1
We present an updated transit ephemeris for the exoplanet WASP-18 b and critically examine the existence of a proposed second planet, WASP-18 c. Using 205 transit light curves from…
Limits on the Post-eclipse Emission Spectrum of HD 80606 b From High-Resolution Spectroscop
Luke Finnerty, Aurora Kesseli, Kyle Pearson +2
We present Keck/NIRSPEC -band observations of HD 80606 b, one of the most eccentric known exoplanets. HD 80606 b was observed after secondary eclipse, close to periastron, when…
Three New Light Curves and Updated Transit Timings of WASP-135 b
Kristine Kate Torres, Isabela G. Huckabee, Patrizia Phem Odo +14
We present updated transit timing measurements for the hot Jupiter WASP-135 b using three new ground-based transit observations obtained with Leia, a 0.6-meter telescope operated b…
A New Approach to Compiling Exoatmospheric Target Lists And Quantifying the Ground-Based Resources Needed to Vet Them
Jennifer A. Burt, Robert T. Zellem, David R. Ciardi +8
Transiting exoplanet atmospheric characterization is currently in a golden age as dozens of exoplanet atmospheres are being studied by NASA's Hubble and James Webb Space Telescopes…
Enhancing Exoplanet Ephemerides by Leveraging Professional and Citizen Science Data: A Test Case with WASP-77A b
Federico R. Noguer, Suber Corley, Kyle A. Pearson +42
We present an updated ephemeris and physical parameters for the exoplanet WASP-77 A b. In this effort, we combine 64 ground- and space-based transit observations, 6 space-based ecl…
An Orbital Solution for WASP-12 b: Updated Ephemeris and Evidence for Decay Leveraging Citizen Science Data
Avinash S. Nediyedath, Martin J. Fowler, A. Norris +11
NASA Citizen Scientists have used Exoplanet Transit Interpretation Code (EXOTIC) to reduce 40 sets of time-series images of WASP-12 taken by privately owned telescopes and a 6-inch…
