Instrument models (IMs) enable the reduction of systematic error in transit spectroscopy light-curve data, but, since the model formulation can influence the estimation of science model parameters, characterization of the instrument model effects is crucial to the interpretation of the reduced data. We analyze a simple instrument model and assess its validity and performance across Hubble WFC3 and STIS instruments. Over a large, n = 63, sample of observed targets, a Markov chain Monte Carlo…

A Temperature Trend for Clouds and Hazes in Exoplanet Atmospheres

The transmission spectra of exoplanet atmospheres observed with the Hubble Space Telescope (HST) in the near-infrared range (1.1–1.65 μm) frequently show evidence for some combination of clouds and



Reliable inference of exoplanet light-curve parameters using deterministic and stochastic systematics models

Time-series photometry and spectroscopy of transiting exoplanets allow us to study their atmospheres. Unfortunately, the required precision to extract atmospheric information surpasses the design

ExoTiC-ISM: A Python package for marginalised exoplanet transit parameters across a grid of systematic instrument models

By modularisation of the code and implementation of more systematic grids, ExoTiC-ISM can be used for other instruments, and an implementation for select detectors on the James Webb Space Telescope (JWST) will provide robust transit spectra in the future.

Bayesian Methods for Joint Exoplanet Transit Detection and Systematic Noise Characterization

Joint detection efficiency is specifically improved for short-period, low transit-depth exoplanet transits, providing evidence in support of the hypothesis that joint detection may indeed help to mitigate overfitting.

Analyzing Eight Years of Transiting Exoplanet Observations Using WFC3's Spatial Scan Monitor

HST/WFC3's spatial scan monitor automatically reduces and analyzes time-series data taken in spatial scan mode with the IR grisms. Here we describe the spatial scan monitor pipeline and present

An HST/STIS Optical Transmission Spectrum of Warm Neptune GJ 436b

GJ 436b is a prime target for understanding warm Neptune exoplanet atmospheres and a target for multiple James Webb Space Telescope (JWST) Guaranteed Time Observation programs. Here, we report the

PandExo: A Community Tool for Transiting Exoplanet Science with JWST & HST

As we approach the James Webb Space Telescope (JWST) era, several studies have emerged that aim to (1) characterize how the instruments will perform and (2) determine what atmospheric spectral

Disequilibrium Chemistry in Exoplanet Atmospheres Observed with the Hubble Space Telescope

Literature on the theory of exoplanet atmospheric disequilibrium chemistry is rich, although its observational counterpart has yet to emerge beyond the hints provided by a few targets in dedicated

Robust radio interferometric calibration using the t-distribution

This paper proposes to improve the robustness of calibration by using a noise model based on the Student's t distribution, which uses Expectation Maximization when the authors have a student's t noise model and the Levenberg-Marquardt algorithm in the maximization step.

Detection of an Atmosphere on a Rocky Exoplanet

We report the detection of an atmosphere on a rocky exoplanet, GJ 1132 b, which is similar to Earth in terms of size and density. The atmospheric transmission spectrum was detected using Hubble WFC3

A continuum from clear to cloudy hot-Jupiter exoplanets without primordial water depletion

The difference between the planetary radius measured at optical and infrared wavelengths is an effective metric for distinguishing different atmosphere types, so that strong water absorption lines are seen in clear-atmosphere planets and the weakest features are associated with clouds and hazes.
