Adaptive Online Emulation for Accelerating Complex Physical Simulations
Tara P. A. Tahseen, Nikolaos Nikolaou, LuÃs 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? 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…
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…
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 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…
