Finding Extrasolar Planets in the Stellar Graveyard with the Hubble Space Telescope
John H. Debes, Steinn Sigurdsson, Bruce E. Woodgate
In order to directly image an extrasolar planet, the large contrast between a star and a companion planet must be overcome. White Dwarfs (WDs) are the remnants of stars > 1 M_sun a…

High Contrast Imaging with Gaussian Aperture Pupil Masks
J. H. Debes, J. Ge, C. Mendelowitz +1
Gaussian aperture pupil masks (GAPMs) can in theory achieve the contrast requisite for directly imaging an extrasolar planet. We outline the process of fabricating and testing a GA…

High Contrast Imaging of Extrasolar Planets
John H. Debes, Jian Ge
Gaussian aperture pupil masks (GAPMs) can in theory achieve the contrast requisite for directly imaging an extrasolar planet. We use lab tests and simulations to further study thei…
