High-cadence, high-contrast imaging for exoplanet mapping: observations of the HR 8799 planets with VLT/SPHERE satellite-spot-corrected relative photometry

D Apai, M Kasper, A Skemer, JR Hanson… - The Astrophysical …, 2016 - iopscience.iop.org
Time-resolved photometry is an important new probe of the physics of condensate clouds in
extrasolar planets and brown dwarfs. Extreme adaptive optics systems can directly image …

VLT/SPHERE multiwavelength high-contrast imaging of the HD 115600 debris disk: new constraints on the dust geometry and the presence of young giant planets

A Gibbs, K Wagner, D Apai, A Moór… - The Astronomical …, 2019 - iopscience.iop.org
Young and dynamically active planetary systems can form disks of debris that are easier to
image than the planets themselves. The morphology and evolution of these disks can help …

Imaging Forming Planetary Systems Towards Imaging Exo-Earths

KR Wagner - 2020 - search.proquest.com
Thousands of exoplanets have been discovered, although very few have been directly
observed. Direct imaging and spectroscopy of the thermal or reflected light from exoplanets …

Discovery of a Two-Armed Spiral Structure in the Gapped Disk in HD 100453

K Wagner, D Apai, M Kasper, M Robberto - arXiv preprint arXiv …, 2015 - arxiv.org
We present VLT/SPHERE adaptive optics imaging in Y $-$, J $-$, H $-$, and K-bands of the
HD 100453 system and the discovery of a two-armed spiral structure in a disk extending to …
