The NUV transit of XO-3 b
Raven Cilley, Lia Corrales, George W. King +8
Near-UV (NUV) measurements of exoplanet transits offer a means to probe atmospheric escape, cloud formation, and planetary magnetic fields. We examine a 2024 XMM-Newton Optical Mon…
Stellar X-ray variability and planetary evolution in the DS Tucanae system
George W. King, Lía R. Corrales, Vincent Bourrier +5
We present an analysis of four Chandra observations of the 45 Myr old DS Tuc binary system. We observed X-ray variability of both stars on timescales from hours to months, includin…
Generating X-ray transit profiles with batman
George W. King, Lía R. Corrales, Peter J. Wheatley +2
We present an adaptation of the exoplanet transit model code batman, in order to permit the generation of X-ray transits. Our underlying extended coronal model assumes an isotherma…
High-energy spectra of LTT 1445A and GJ 486 reveal flares and activity
H. Diamond-Lowe, G. W. King, A. Youngblood +19
The high-energy radiative output, from the X-ray to the ultraviolet, of exoplanet host stars drives photochemical reactions and mass loss in the upper regions of planetary atmosphe…
Detecting exoplanet transits with the next generation of X-ray telescopes
Raven Cilley, George W. King, Lia Corrales
Detecting exoplanet transits at X-ray wavelengths would provide a window into the effects of high energy irradiation on the upper atmospheres of planets. However, stars are relativ…
Exoplanet Aeronomy: A Case Study of WASP-69b's Variable Thermosphere
W. Garrett Levine, Shreyas Vissapragada, Adina D. Feinstein +5
Aeronomy, the study of Earth's upper atmosphere and its interaction with the local space environment, has long traced changes in the thermospheres of Earth and other solar system p…
The XUV-driven escape of the planets around TOI-431 & Lupi
George W. King, Lía R. Corrales, Jorge Fernández Fernández +4
One of the leading mechanisms invoked to explain the existence of the radius valley is atmospheric mass loss driven by X-ray and extreme-ultraviolet irradiation, with this process…
