The Open-source Photochem Code: A General Chemical and Climate Model for Interpreting (Exo)Planet Observations

The Planetary Science Journal
With the launch of the James Webb Space Telescope, we are firmly in the era of exoplanet atmosphere characterization. Understanding exoplanet spectra requires atmospheric simulations that span the diversity of planetary atmospheres.

Limited Hysteresis in the Atmospheric Dynamics of Hot Jupiters

The Astrophysical Journal
Over the past two decades, a coherent picture has emerged of the atmospheric dynamics of hot Jupiters from a combination of three-dimensional general circulation models and astronomical observations.

Exoplanet Atmospheres at High Spectral Resolution

Annual Review of Astronomy and Astrophysics
High-resolution spectroscopy (HRS) has grown into one of the main techniques for characterizing the atmospheres of extrasolar planets. High spectral resolving power allows for the efficient removal of telluric and host-star contamination. Combined with the large collecting area of ground-based telescopes, it enables detailed studies of atmospheric ...

Towards Atmospheric Characterisation of Exoplanets

, 2014
This thesis provides a multi-pronged approach towards paving the way for future space and ground based exoplanet characterisation e↵orts as well as providing new analysis of the atmosphere of the exoplanet HD 179949 b. This is done, firstly, by outlining engineering trade studies conducted for the attitude and orbit control system (AOCS) and sun shield

Minimizing Star-spot Contamination of Exoplanet Transit Spectroscopy Using Alternate Normalization

The Astronomical Journal
Recently, M. H. Currie et al. (2023) simulated the detection of molecules in the atmospheres of temperate rocky exoplanets transiting nearby M-dwarf stars.

Comparing Results from Two Uniform Phase-curve Surveys

The Astronomical Journal
We present a comparison of the two most recent and comprehensive Spitzer phase curve studies—L. Dang et al. and M. R. Swain et al.—which report analyses of the Spitzer 4.5 μ m phase curves.

Uniform Reinterpretation of Rocky Exoplanet Secondary Eclipse Observations and the Impact of Stellar and Orbital Uncertainties

The Astronomical Journal
Secondary eclipse observations are a powerful way to investigate whether or not a rocky exoplanet hosts an atmosphere, as an atmospheric presence would transport heat to the nightside and render the dayside colder than anticipated.

Tropical Cyclones on Tidally Locked Rocky Planets: Dependence on Rotation Period

The Astrophysical Journal
Tropical cyclones occur over the Earth’s tropical oceans, with characteristic genesis regions and tracks tied to the warm ocean surface that provide energy to sustain these storms.
