Obliquity Evolution of the Potentially Habitable Exoplanet Kepler-62f [PDF]
Astrobiology, 2020 Variations in the axial tilt, or obliquity, of terrestrial planets can affect their climates and therefore their habitability. Kepler-62f is a 1.4 R ⊕ planet orbiting within the habitable zone of its K2 dwarf host star.

The Apparent Tidal Decay of WASP-4 b Can Be Explained by the Rømer Effect
Universe, 2023 Tidal orbital decay plays a vital role in the evolution of hot Jupiter systems. As of now, this has only been observationally confirmed for the WASP-12 system.

The Evolution of Atmospheric Escape of Highly Irradiated Gassy Exoplanets
Proceedings of the International Astronomical Union, 2021 AbstractAtmospheric escape has traditionally been observed using hydrogen Lyman-α transits, but more recent detections utilise the metastable helium triplet lines at 1083nm. Capable of being observed from the ground, this helium signature offers new possibilities for studying atmospheric escape.

Habitable Zone Lifetime of Exoplanets around Main Sequence Stars [PDF]
, 2013 Funding: Dean's Scholarship at the University of East Anglia.The potential habitability of newly discovered exoplanets is initially assessed by determining whether their orbits fall within the circumstellar habitable zone of their star.

TOI-1136 is a Young, Coplanar, Aligned Planetary System in a Pristine Resonant Chain
The Astronomical Journal, 2023 Convergent disk migration has long been suspected to be responsible for forming planetary systems with a chain of mean-motion resonances (MMRs). Dynamical evolution over time could disrupt the delicate resonant configuration. We present TOI-1136, a 700 ±

Solar System Research, 2010 After the discovery of more than 400 planets beyond our Solar System, the characterization of exoplanets as well as their host stars can be considered as one of the fastest growing fields in space science during the past decade. The characterization of exoplanets can only be carried out in a well coordinated interdisciplinary way which connects ...

Exoplanet atmosphere evolution: emulation with random forests.
CoRR, 2021 ABSTRACT Atmospheric mass-loss is known to play a leading role in sculpting the demographics of small, close-in exoplanets. Knowledge of how such planets evolve allows one to ‘rewind the clock’ to infer the conditions in which they formed.

Abiotic ozone and oxygen in atmospheres similar to prebiotic earth [PDF]
, 2014 The search for life on planets outside our solar system will use spectroscopic identification of atmospheric biosignatures. The most robust remotely detectable potential biosignature is considered to be the detection of oxygen (O2) or ozone (O3 ...
