SPIDERMAN: an open-source code to model phase curves and secondary eclipses
Tom Louden, Laura Kreidberg
We present SPIDERMAN, a fast code for calculating exoplanet phase curves and secondary eclipses with arbitrary surface brightness distributions in two dimensions. Using a geometric…
The Science Case for an Extended Spitzer Mission
Jennifer C. Yee, Giovanni G. Fazio, Robert Benjamin +45
Although the final observations of the Spitzer Warm Mission are currently scheduled for March 2019, it can continue operations through the end of the decade with no loss of photome…
Trends in Atmospheric Properties of Neptune-Size Exoplanets
Ian J. M. Crossfield, Laura Kreidberg
Precise atmospheric observations have been made for a growing sample of warm Neptunes. Here we investigate the correlations between these observations and a large number of system…
Water, High-Altitude Condensates, and Possible Methane Depletion in the Atmosphere of the Warm Super-Neptune WASP-107b
Laura Kreidberg, Michael R. Line, Daniel Thorngren +2
The super-Neptune exoplanet WASP-107b is an exciting target for atmosphere characterization. It has an unusually large atmospheric scale height and a small, bright host star, raisi…
Exoplanet Atmosphere Measurements from Transmission Spectroscopy and other Planet-Star Combined Light Observations
Laura Kreidberg
It is possible to learn a great deal about exoplanet atmospheres even when we cannot spatially resolve the planets from their host stars. In this chapter, we overview the basic tec…
Observing the Atmospheres of Known Temperate Earth-sized Planets with JWST
Caroline V. Morley, Laura Kreidberg, Zafar Rustamkulov +2
Nine transiting Earth-sized planets have recently been discovered around nearby late M dwarfs, including the TRAPPIST-1 planets and two planets discovered by the MEarth survey, GJ…
Quantifying the Impact of Spectral Coverage on the Retrieval of Molecular Abundances from Exoplanet Transmission Spectra
John W. Chapman, Robert T. Zellem, Michael R. Line +14
Using forward models for representative exoplanet atmospheres and a radiometric instrument model, we have generated synthetic observational data to explore how well the major C- an…
A Multi-Planet System Transiting the = 9 Rapidly Rotating F-Star HD 106315
Joseph E. Rodriguez, George Zhou, Andrew Vanderburg +10
We report the discovery of a multi-planet system orbiting HD 106315, a rapidly rotating mid F-type star, using data from the K2 mission. HD 106315 hosts a s…
