WFIRST-AFTA Coronagraph Science Yield Modeling with EXOSIMS
Dmitry Savransky, Daniel Garrett
We present and discuss the design details of an extensible, modular, open source software framework called EXOSIMS, which creates end-to-end simulations of space-based exoplanet im…
Direct imaging of an asymmetric debris disk in the HD 106906 planetary system
Paul G. Kalas, Abhijith Rajan, Jason J. Wang +53
We present the first scattered light detections of the HD 106906 debris disk using Gemini/GPI in the infrared and HST/ACS in the optical. HD 106906 is a 13 Myr old F5V star in the…
Discovery and spectroscopy of the young Jovian planet 51 Eri b with the Gemini Planet Imager
B. Macintosh, J. R. Graham, T. Barman +85
Directly detecting thermal emission from young extrasolar planets allows measurement of their atmospheric composition and luminosity, which is influenced by their formation mechani…
Wide-Field InfrarRed Survey Telescope-Astrophysics Focused Telescope Assets WFIRST-AFTA 2015 Report
D. Spergel, N. Gehrels, C. Baltay +52
This report describes the 2014 study by the Science Definition Team (SDT) of the Wide-Field Infrared Survey Telescope (WFIRST) mission. It is a space observatory that will address…
Sequential Covariance Calculation for Exoplanet Image Processing
Dmitry Savransky
Direct imaging of exoplanets involves the extraction of very faint signals from highly noisy data sets, with noise that often exhibits significant spatial, spectral and temporal co…
