Velocity-imaging the rapidly precessing planetary disc around the white dwarf HE 1349-2305 using Doppler tomography
Christopher J. Manser, Erik Dennihy, Boris T. Gänsicke +11
The presence of planetary material in white dwarf atmospheres, thought to be accreted from a dusty debris disc produced via the tidal disruption of a planetesimal, is common. Appro…
Differentiating Modern and Prebiotic Earth Scenarios for TRAPPIST-1e: High-resolution Transmission Spectra and Predictions for JWST
Zifan Lin, Ryan J. MacDonald, Lisa Kaltenegger +1
The TRAPPIST-1 system is a priority target for terrestrial exoplanet characterization. TRAPPIST-1e, residing in the habitable zone, will be observed during the JWST GTO Program. He…
The High-Energy Radiation Environment Around a 10 Gyr M Dwarf: Habitable at Last?
Kevin France, Girish Duvvuri, Hilary Egan +20
High levels of X-ray and UV activity on young M dwarfs may drive rapid atmospheric escape on temperate, terrestrial planets orbiting within the liquid water habitable zone. However…
Astro 2020 Science White Paper: Evolved Planetary Systems around White Dwarfs
Boris Gaensicke, Martin Barstow, Amy Bonsor +25
Practically all known planet hosts will evolve into white dwarfs, and large parts of their planetary systems will survive this transition - the same is true for the solar system be…
A planetesimal orbiting within the debris disc around a white dwarf star
Christopher J. Manser, Boris T. Gänsicke, Siegfried Eggl +29
Many white dwarf stars show signs of having accreted smaller bodies, implying that they may host planetary systems. A small number of these systems contain gaseous debris discs, vi…
Carbon to oxygen ratios in extrasolar planetesimals
David J. Wilson, Boris T. Gaensicke, Jay Farihi +1
Observations of small extrasolar planets with a wide range of densities imply a variety of planetary compositions and structures. Currently, the only technique to measure the bulk…
