Speckle suppression and companion detection using coherent differential imaging
Michael Bottom, J. Kent Wallace, Randall D. Bartos +2
Residual speckles due to aberrations arising from optical errors after the split between the wavefront sensor and the science camera path are the most significant barriers to imagi…
Stellar Double Coronagraph: a multistage coronagraphic platform at Palomar observatory
Michael Bottom, J. Chris Shelton, James K. Wallace +6
We present a new instrument, the "Stellar Double Coronagraph" (SDC), a flexible coronagraphic platform. Designed for Palomar Observatory's 200" Hale telescope, its two focal and pu…
Retrieval of Precise Radial Velocities from Near-Infrared High Resolution Spectra of Low Mass Stars
Peter Gao, Peter Plavchan, Jonathan Gagné +21
Given that low-mass stars have intrinsically low luminosities at optical wavelengths and a propensity for stellar activity, it is advantageous for radial velocity (RV) surveys of t…
