ESCAPE: a small explorer mission to study the stellar drivers of exoplanet evolution
Allison Youngblood, Kevin France, Brian Fleming +37
The long-term stability of exoplanetary atmospheres depends critically on the extreme-ultraviolet (EUV) photon and high-energy particle fluxes from the host star, which are poorly…
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…
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…
MOVES III. Simultaneous X-ray and ultraviolet observations unveiling the variable environment of the hot Jupiter HD 189733b
V. Bourrier, P. J. Wheatley, A. Lecavelier des Etangs +8
In this third paper of the MOVES (Multiwavelength Observations of an eVaporating Exoplanet and its Star) programme, we combine Hubble Space Telescope far-ultraviolet observations w…
Magnetism, X-rays, and Accretion Rates in WD 1145+017 and other Polluted White Dwarf Systems
J. Farihi, L. Fossati, P. J. Wheatley +9
This paper reports circular spectropolarimetry and X-ray observations of several polluted white dwarfs including WD 1145+017, with the aim to constrain the behavior of disk materia…
