Of the approximately 25 directly imaged planets to date, all are younger than 500 Myr, and but six 100 Myr (ref.
We present a generalized non-negative factorization (NMF)-based data reduction pipeline for circumstellar disk and exoplanet detection. By using an adaptable pre-processing routine that applies algorithmic masks corrections to improper data, we are able easily offload the computationally-intensive NMF algorithm Graphics Processing Unit (GPU), significantly increasing computational efficiency. has been shown better preserve structural features compared other post-processing approaches...
New development approaches, including launch vehicles and advances in sensors, computing, software, have lowered the cost of entry into space, enabled a revolution low-cost, high-risk Small Satellite (SmallSat) missions. To bring about similar transformation larger space telescopes, it is necessary to reconsider full paradigm observatories. Here we will review history telescope drivers, describe an example conceptual design for low 6.5 m optical enable new science when operated at room...
Epsilon Eridani ($\epsilon$ Eri) is one of the first debris disk systems detected by Infrared Astronomical Satellite (IRAS). However, system has thus far eluded detection in scattered light with no components having been directly imaged. Its similarity to a relatively young Solar System combined its proximity makes it an excellent candidate further our understanding planetary evolution. We present set coronagraphic images taken using Space Telescope Imaging Spectrograph (STIS) coronagraph on...
