Spectroscopic Monitoring of Metal Lines in Polluted White Dwarfs

Laura K. Rogers, Michael M. Shara, Amy Bonsor +12

The disruption and accretion of planetary material onto white dwarfs is expected to be inherently dynamic and stochastic, potentially driving variability in the accretion rate and…

White dwarf planetary systems in the ultraviolet

Jamie Williams, Amy Bonsor, Boris Gänsicke +9

Almost every known planet host will evolve into a white dwarf, and the surviving planetary material will continue to orbit this stellar remnant. Asteroids perturbed onto star-grazi…

From Hubble to HWO: Bridging the Frontier of White Dwarf Exoplanet Science

Laura K. Rogers, Siyi Xu, Martin Barstow +20

White dwarf stars, the endpoint of stellar evolution for 97% of stars in our Milky Way, offer a unique and powerful window into the bulk elemental composition of rocky exoplanetary…

Observations of Exocomets

Judith Korth, Azib Norazman, Raphäel Bendahan-West +6

Active small bodies in extrasolar systems, the extrasolar analogues of Solar System comets, provide insights into the orbital evolution and physical processes shaping planetary sys…

Thermal Emission and Confirmation of the Frigid White Dwarf Exoplanet WD 1856+534b

Mary Anne Limbach, Andrew Vanderburg, Ryan J. MacDonald +12

We report the detection of thermal emission from and confirm the planetary nature of WD 1856+534b, the first transiting planet known to orbit a white dwarf star. Observations with…

Host-star and exoplanet composition: Polluted white dwarf reveals depletion of moderately refractory elements in planetary material

Claudia Aguilera-Gómez, Laura K. Rogers, Amy Bonsor +6

Planets form from the same cloud of molecular gas and dust as their host stars. Confirming if planetary bodies acquire the same refractory element composition as their natal disc d…

The MIRI Exoplanets Orbiting White Dwarfs (MEOW) Survey: Mid-Infrared Excess Reveals a Giant Planet Candidate around a Nearby White Dwarf

Mary Anne Limbach, Andrew Vanderburg, Alexander Venner +17

The MIRI Exoplanets Orbiting White dwarfs (MEOW) Survey is a cycle 2 JWST program to search for exoplanets around dozens of nearby white dwarfs via infrared excess and direct imagi…

Gemini/GMOS Transmission Spectroscopy of the Grazing Planet Candidate WD 1856+534 b

Siyi Xu, Hannah Diamond-Lowe, Ryan J. MacDonald +12

WD 1856+534 b is a Jupiter-sized, cool giant planet candidate transiting the white dwarf WD 1856+534. Here, we report an optical transmission spectrum of WD 1856+534 b obtained fro…

Host-star and exoplanet compositions: a pilot study usinga wide binary with a polluted white dwarf

Amy Bonsor, Paula Jofre, Oliver Shorttle +3

Planets and stars ultimately form out of the collapse of the same cloud of gas. Whilst planets, and planetary bodies, readily loose volatiles, a common hypothesis is that they reta…

Near-infrared variability in dusty white dwarfs: tracing the accretion of planetary material

Laura K. Rogers, Siyi Xu, Amy Bonsor +4

The inwards scattering of planetesimals towards white dwarfs is expected to be a stochastic process with variability on human time-scales. The planetesimals tidally disrupt at the…
