Is ozone a reliable proxy for molecular oxygen? III. The impact of CH on the O-O relationship for Earth-like atmospheres
Thea Kozakis, João M. Mendonça, Lars A. Buchhave +1
In the search for life in the Universe, molecular oxygen (O) combined with a reducing species, such as methane (CH), is considered a promising disequilibrium biosignature.…
Hot Rocks Survey IV: Emission from LTT 3780 b is consistent with a bare rock
Natalie H. Allen, Néstor Espinoza, Hannah Diamond-Lowe +19
It is an open question whether small planets around M dwarfs are able to maintain atmospheres. The Hot Rocks Survey aims to address this question by observing 9 rocky exoplanets or…
Adaptive Online Emulation for Accelerating Complex Physical Simulations
Tara P. A. Tahseen, Nikolaos Nikolaou, Luís F. Simões +3
Complex physical simulations often require trade-offs between model fidelity and computational feasibility. We introduce Adaptive Online Emulation (AOE), which dynamically learns n…
Is Ozone a Reliable Proxy for Molecular Oxygen? II. The impact of NO on the O-O relationship for Earth-like atmospheres
Thea Kozakis, João M. Mendonça, Lars A. Buchhave +1
Molecular oxygen (O2) will be an important molecule in the search for biosignatures in terrestrial planetary atmospheres in the coming decades. In particular, O2 combined with a re…
Hot Rocks Survey III: A deep eclipse for LHS 1140c and a new Gaussian process method to account for correlated noise in individual pixels
Mark Fortune, Neale P. Gibson, Hannah Diamond-Lowe +14
Time-series photometry at mid-infrared wavelengths is becoming a common technique to search for atmospheres around rocky exoplanets. This method constrains the brightness temperatu…
Hot Rocks Survey II: The thermal emission of TOI-1468 b reveals a hot bare rock
E. A. Meier Valdés, B. -O. Demory, H. Diamond-Lowe +17
Terrestrial exoplanets orbiting nearby small, cool stars known as M dwarfs are well suited for atmospheric characterisation. Given the strong XUV irradiation from M dwarf host star…
Simultaneous retrieval of orbital phase resolved JWST/MIRI emission spectra of the hot Jupiter WASP-43b: evidence of water, ammonia and carbon monoxide
Jingxuan Yang, Mark Hammond, Anjali A. A. Piette +14
Spectroscopic phase curves of hot Jupiters measure their emission spectra at multiple orbital phases, thus enabling detailed characterisation of their atmospheres. Precise constrai…
Nightside clouds and disequilibrium chemistry on the hot Jupiter WASP-43b
Taylor J. Bell, Nicolas Crouzet, Patricio E. Cubillos +80
Hot Jupiters are among the best-studied exoplanets, but it is still poorly understood how their chemical composition and cloud properties vary with longitude. Theoretical models pr…
The THOR+HELIOS general circulation model: multi-wavelength radiative transfer with accurate scattering by clouds/hazes
Russell Deitrick, Kevin Heng, Urs Schroffenegger +5
General circulation models (GCMs) provide context for interpreting multi-wavelength, multi-phase data of the atmospheres of tidally locked exoplanets. In the current study, the non…
TOI-1518b: A Misaligned Ultra-hot Jupiter with Iron in its Atmosphere
Samuel H. C. Cabot, Aaron Bello-Arufe, João M. Mendonça +36
We present the discovery of TOI-1518b -- an ultra-hot Jupiter orbiting a bright star . The transiting planet is confirmed using high-resolution optical transmission spect…
The obliquity and atmosphere of the ultra-hot Jupiter TOI-1431b (MASCARA-5b): A misaligned orbit and no signs of atomic ormolecular absorptions
M. Stangret, E. Pallé, N. Casasayas-Barris +21
Ultra-hot Jupiters are defined as giant planets with equilibrium temperatures larger than 2000 K. Most of them are found orbiting bright A-F type stars, making them extremely suita…
Ariel: Enabling planetary science across light-years
Giovanna Tinetti, Paul Eccleston, Carole Haswell +313
Ariel, the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, was adopted as the fourth medium-class mission in ESA's Cosmic Vision programme to be launched in 2029. Durin…
Angular Momentum and Heat Transport on Tidally Locked Hot Jupiter Planets
João M. Mendonça
The atmospheric circulation in the upper atmosphere of hot Jupiter planets is strongly influenced by the incoming stellar radiation. In this work we explore the results from a 3D a…
