X-ray and UV radiation in the planet-forming T-Tauri system PDS 70. Signs of accretion and coronal activity
Simon R. G. Joyce, John P. Pye, Jonathan D. Nichols +3
Planet formation takes place in protoplanetary discs around young T-Tauri stars. PDS 70 is one of the first confirmed examples of a system where the planets are currently forming i…
ExoplANETS-A: A VO database for host stars and planetary systems: The effect of XUV on planet atmospheres
M. Morales-Calderón, S. R. G. Joyce, J. P. Pye +12
ExoplANETS-A is an EU Horizon-2020 project with the primary objective of establishing new knowledge on exoplanet atmospheres. Intimately related to this topic is the study of the h…
The K2-3 system revisited: testing photoevaporation and core-powered mass loss with three small planets spanning the radius valley
Hannah Diamond-Lowe, Laura Kreidberg, C. E. Harman +11
Multi-planet systems orbiting M dwarfs provide valuable tests of theories of small planet formation and evolution. K2-3 is an early M dwarf hosting three small exoplanets (1.5-2.0…
A Swift view of X-ray and UV radiation in the planet-forming T-Tauri system PDS 70
Simon Joyce, John Pye, Jonathan Nichols +4
PDS 70 is a 5 Myr old star with a gas and dust disc in which several proto-planets have been discovered. We present the first UV detection of the system along with X-ray obse…
Exoplanet host-star properties: the active environment of exoplanets
John P. Pye, David Barrado, Rafael A. Garcia +12
The primary objectives of the ExoplANETS-A project are to: establish new knowledge on exoplanet atmospheres; establish new insight on influence of the host star on the planet atmos…
The white dwarf mass-radius relation and its dependence on the hydrogen envelope
Alejandra D. Romero, S. O. Kepler, S. R. G. Joyce +2
We present a study of the dependence of the mass-radius relation for DA white dwarf stars on the hydrogen envelope mass and the impact on the value of log g, and thus the determina…
