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

Autor: Li, Jialin, Close, Laird M., Males, Jared R., Haffert, Sebastiaan Y., Weinberger, Alycia, Follette, Katherine, Wagner, Kevin, Apai, Daniel, Wu, Ya-Lin, Long, Joseph D., Perez, Laura, Pearce, Logan A., Kueny, Jay K., McEwen, Eden A., Van Gorkom, Kyle, Guyon, Olivier, Kautz, Maggie Y., Hedglen, Alexander D., Foster, Warren B., Roberts, Roz, Lumbres, Jennifer, Schatz, Lauren

The high contrast and spatial resolution requirements for directly imaging exoplanets requires effective coordination of wavefront control, coronagraphy, observation techniques, and post-processing algorithms. However, even with this suite of tools,

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

Autor: Long, Joseph D., Males, Jared R., Close, Laird M., Guyon, Olivier, Haffert, Sebastiaan Y., Weinberger, Alycia J., Kueny, Jay, Van Gorkom, Kyle, McEwen, Eden, Pearce, Logan, Kautz, Maggie, Li, Jialin, Lumbres, Jennifer, Hedglen, Alexander, Schatz, Lauren, McLeod, Avalon, Doty, Isabella, Foster, Warren B., Roberts, Roswell, Twitchell, Katie

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 (i.e. KLIP) using modes computed from the science images themselves.
