SIOSLab was well represented last month at the 235th AAS Meeting in Honolulu, Hawai’i. Corey Spohn presented his poster on “Dynamically Scheduling Direct Imaging Missions” and Dean Keithly Presented his talk on “Exoplanet classification probabilities from initial detections in a direct imaging mission.” Two members also presented dissertation talks: Jacob Shapiro presented his talk on “Identifying Exoplanets with CSP Filtering and a Forward Model Matched Filter” and Gabriel Soto presented his talk on “Fuel Cost Heuristics for Starshade Retargeting Slew Maneuvers.”
GPI 2.0 Is a Go!
We are very happy to announce that we have secured funding from the NSF and HSF for an upgrade of the Gemini Planet Imager. Once commissioned at Gemini North in Hawaii in 2022, GPI 2.0 will be even more sensitive than the original GPI, and capable of imaging planets around even more distant and fainter stars. For more information, see our Research page, as well as this article in the Cornell Chronicle.

SPIE Optics + Photonics 2019
The SPIE Optics + Photonics conference took place August 11 – 16 in San Diego. The SIOSLab attended, and presented two talks: Optical design of a modular segmented space telescope and Exploration of the dynamical phase space of stars with known planets.
Congratulations to Dean Keithly on Passing his A Exam
Dean Keithly successfully passed his A exam on 9/9/2019, marking his entrance into the dissertation phase of his degree program. His presentation can be viewed here.
2019 AAS/AIAA Astrodynamics Specialist Conference
The 2019 AAS/AIAA Astrodynamics Specialist Conference took place between August 11th-16th in Portland, Maine this year. I presented my talk titled “Solar Sail Trajectories and Orbit Phasing of Modular Spacecraft for Segmented Telescope Assembly about Sun-Earth L2.”
New Paper in The Astronomical Journal

Our new paper entitled “Detecting Planets from Direct-imaging Observations Using Common Spatial Pattern Filtering” has been published in The Astronomical Journal. It can be found here.
JGCD Paper Published
Our new paper, titled
“Parameterizing the Search Space of Starshade Fuel Costs for Optimal Observation Scheduling” has been published in the Journal of Guidance, Control & Dynamics. The paper can be accessed here.
AAS 233rd Meeting
Our lab attended the 233rd AAS Meeting in drizzly Seattle, Washington in early January. Dean Keithly presented his poster titled “Blind Search Single-Visit Exoplanet Direct Imaging Yield for Space Based Telescopes.” Jacob Shapiro presented his poster “Optical Design of a Large Segmented Space Telescope.” Dmitry Savransky presented a talk titled “Simulating Known Exoplanet Orbits for WFIRST CGI Imaging.” Gabriel Soto presented a poster titled “Navigation and Orbit Phasing of Modular Spacecraft for Segmented Telescope Assembly about Sun-Earth L2.”
