Long-term variability in debris transiting white dwarfs
Amornrat Aungwerojwit, Boris T. Gaensicke, Vikram S. Dhillon +7
Combining archival photometric observations from multiple large-area surveys spanning the past 17 years, we detect long-term variability in the light curves of ZTFJ032833.52-121945…
TESS Duotransit Candidates from the Southern Ecliptic Hemisphere
Faith Hawthorn, Sam Gill, Daniel Bayliss +20
Discovering transiting exoplanets with long orbital periods allows us to study warm and cool planetary systems with temperatures similar to the planets in our own Solar system. The…
The frequency of gaseous debris discs around white dwarfs
Christopher J. Manser, Boris T. Gänsicke, Nicola Pietro Gentile Fusillo +5
1-3 per cent of white dwarfs are orbited by planetary dusty debris detectable as infrared emission in excess above the white dwarf flux. In a rare subset of these systems, a gaseou…
