About the NASA Postdoctoral Program
The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.
Description:
The number of known planets around nearby stars continues to increase. The primary goal of this research is the direct detection of the faint emission from such exoplanets and from exozodiacal/debris disks. New high-contrast near-neighbor detection techniques are emerging regularly, and we are working to test and use these approaches at the Palomar Observatory. We now have two facilities available on the Hale 200-inch telescope. The first is an off-axis subaperture on the Hale telescope that is corrected to extreme adaptive optics levels, which allows for testing and observation with a variety of coronagraphs. The second facility is a rotating multi-aperture nuller on the Hale telescope that seeks to demonstrate the complete companion detection strategy envisioned for a rotating space-based nulling interferometer. Interestingly, this interferometer, with an inner working angle as small as 30 milli-arcseconds, may provide a small-angle detection capability superior to that of any coronagraph. Technical work in either or both of these areas is envisioned, as is the observational search for faint companions such as brown dwarfs and hot young planets around nearby stars. Eventually the work should lead to deployment on larger telescopes and in space.
