Notch Filter Masks: Practical Image Masks for Planet-Finding Coronagraphs
Marc J. Kuchner, David N. Spergel
An ideal coronagraph with a band-limited image mask can efficiently image off-axis sources while removing identically all of the light from an on-axis source. However, strict mask…
The Geometry of Resonant Signatures in Debris Disks with Planets
Marc J. Kuchner, Matthew J. Holman
Using simple geometrical arguments, we paint an overview of the variety of resonant structures a single planet with moderate eccentricity (e < ~0.6) can create in a dynamically col…
Long-Term Dynamics and the Orbital Inclinations of the Classical Kuiper Belt Objects
Marc J. Kuchner, Michael E. Brown, Matthew Holman
We numerically integrated the orbits of 1458 particles in the region of the classical Kuiper Belt (41 AU < a < 47 AU) to explore the role of dynamical instabilities in sculpting th…
Halting Planet Migration in the Evacuated Centers of Protoplanetary Disks
Marc J. Kuchner, Myron Lecar
Precise Doppler searches for extrasolar planets find a surfeit of planets with orbital periods of 3-4 days, and no planets with orbital periods less than 3 days. The circumstellar…
A Coronagraph with a Band-Limited Mask for Finding Terrestrial Planets
Marc J. Kuchner, Wesley A. Traub
Several recent designs for planet-finding telescopes use coronagraphs operating at visible wavelengths to suppress starlight along the telescope's optical axis while transmitting a…
