Our newest paper: Keithly, Savransky, and Spohn, “Integration Time Adjusted Completeness” is now available as open access in the Journal of Astronomical Telescopes, Instruments, and Systems. This paper updates the concept of completeness—the probability of detecting an exoplanet from some
On Nutation Dampers
I’ve been teaching the theory of nutation dampers for years, and have finally gotten around to creating a good visualization of one. Nutation dampers are really neat devices for rejecting disturbances on spin-stabilized spacecraft. Essentially, a damper is any mechanical
On Detecting Exoplanets
Here is a lecture I recently did on techniques for the detection of exoplanets: A related video illustrating some of the methods:
On Space Telescopes
I recently had the opportunity to do a guest lecture on astronomy space missions. See below for some fun facts about Hubble and other space telescopes.
Automating Away Life’s Annoyances
For my CV, I like to include a table of citation metrics from multiple sources (currently Google Scholar, ADS and Web of Science). Updating these manually, however, is torturous, and feels like something that should be trivially automatable. I recently
An Aural Experiment
Every year or so, I update my ‘history of exoplanet exploration’ animation, which shows the detections of exoplanets in (roughly) the order of their discovery by plotting the host star locations in sequence. This year, I decided that I wanted
Corey Yells About Computer Stuff
JATIS Paper Published
“Analytical model for starshade formation flying with applications to exoplanet direct imaging observation scheduling,” by Gabriel Soto, Dmitry Savransky, and Rhonda Morgan has been published in the Journal of Astronomical Telescopes, Instruments, and Systems, and is available via open access
On Proposals
At a recent group meeting, we discussed responding to funding opportunities from US funding agencies (mostly NASA). A recording of the discussion is available below. As always, all opinions are strictly my own.
