Challenge of direct imaging of exoplanets within structures: disentangling real signal from point source from background light

Jialin Li, Laird M. Close, Jared R. Males +19

The high contrast and spatial resolution requirements for directly imaging exoplanets requires effective coordination of wavefront control, coronagraphy, observation techniques, an…

On-sky, real-time optical gain calibration on MagAO-X using incoherent speckles

Eden A. McEwen, Jared R. Males, Olivier Guyon +15

The next generation of extreme adaptive optics (AO) must be calibrated exceptionally well to achieve the desired contrast for ground-based direct imaging exoplanet targets. Current…

High-Contrast Imaging at First-Light of the GMT: The Preliminary Design of GMagAO-X

Jared R. Males, Laird M. Close, Sebastiaan Y. Haffert +15

We present the preliminary design of GMagAO-X, the first-light high-contrast imager planned for the Giant Magellan Telescope. GMagAO-X will realize the revolutionary increase in sp…

More data than you want, less data than you need: machine learning approaches to starlight subtraction with MagAO-X

Joseph D. Long, Jared R. Males, Laird M. Close +17

High-contrast imaging data analysis depends on removing residual starlight from the host star to reveal planets and disks. Most observers do this with principal components analysis…

MagAO-X: Commissioning Results and Status of Ongoing Upgrades

Jared R. Males, Laird M. Close, Sebastiaan Y. Haffert +20

MagAO-X is the coronagraphic extreme adaptive optics system for the 6.5 m Magellan Clay Telescope. We report the results of commissioning the first phase of MagAO-X. Components now…

Debris Disks can Contaminate Mid-Infrared Exoplanet Spectra: Evidence for a Circumstellar Debris Disk around Exoplanet Host WASP-39

Laura Flagg, Alycia J. Weinberger, Taylor J. Bell +21

The signal from a transiting planet can be diluted by astrophysical contamination. In the case of circumstellar debris disks, this contamination could start in the mid-infrared and…
