  • Title of programme: Planetary Material Orbiting White Dwarfs
  • Abstract: White dwarfs are the final evolutionary phase of 95% of stars, and therefore the fated host stars of many exoplanets. White dwarf spectroscopy shows that nearly half of white dwarfs contain metals in their atmospheres, which must have been accreted from metal-rich planetary material that survived the red giant phase of stellar evolution. We can use metal pollution in white dwarf atmospheres as sirens, alerting us to recent accretion, in order to prioritize an efficient sample of white dwarfs to search for transiting planetary debris. We propose to observe seven of the nearest, brightest, metal-polluted white dwarfs with CHEOPS for periodic photometric variations due to orbiting material.

Mission Description CHEOPS (Benz et al., https://doi.org/10.1007/s10686-020-09679-4) is a European Space Agency (ESA) mission in partnership with Switzerland with important contributions to the payload and the ground segment from Austria, Belgium, France, Germany, Hungary, Italy, Portugal, Spain, Sweden and the United Kingdom.

The satellite has a single payload comprising an ultra-high precision photometer covering the 330 - 1100 nm wavelength range in a single photometric band. Observations are made as part of the Guaranteed Time Observing Programme that is formulated by the CHEOPS Science Team, and the Guest Observers Programme through which the Community at large can apply for CHEOPS time.
