A compact multi-planet system transiting HIP 29442 (TOI-469) discovered by TESS and ESPRESSO. Radial velocities lead to the detection of transits with low signal-to-noise ratio
M. Damasso, J. Rodrigues, A. Castro-González +52
We followed-up with ESPRESSO the K0V star HIP 29442 (TOI-469), already known to host a validated sub-Neptune companion TOI-469.01. We aim to verify the planetary nature of TOI-469.…
Mapping out the parameter space for photoevaporation and core-powered mass-loss
James E. Owen, Hilke E. Schlichting
Understanding atmospheric escape in close-in exoplanets is critical to interpreting their evolution. We map out the parameter space over which photoevaporation and core-powered mas…
Extreme evaporation of planets in hot thermally unstable protoplanetary discs: the case of FU Ori
Sergei Nayakshin, James E. Owen, Vardan Elbakyan
Disc accretion rate onto low mass protostar FU Ori suddenly increased hundreds of times 85 years ago and remains elevated to this day. We show that the sum of historic and recent o…
The evolution of catastrophically evaporating rocky planets
Alfred Curry, Richard Booth, James E. Owen +1
In this work, we develop a rocky planet interior model and use it to investigate the evolution of catastrophically evaporating rocky exoplanets. These planets, detected through the…
Using helium 10830 Å transits to constrain planetary magnetic fields
Ethan Schreyer, James E. Owen, Jessica J. Spake +2
Planetary magnetic fields can affect the predicted mass loss rate for close-in planets that experience large amounts of UV irradiation. In this work, we present a method to detect…
Why the observed spin evolution of older-than-solar like stars might not require a dynamo mode change
Ketevan Kotorashvili, Eric G. Blackman, James E. Owen
The spin evolution of main sequence stars has long been of interest for basic stellar evolution, stellar aging, stellar activity, and consequent influence on companion planets. Obs…
