Discovering M-Dwarf Companions with STEPS
S. H. Pravdo, S. B. Shaklan, J. Lloyd +1
The Stellar Planet Survey (STEPS) is an ongoing astrometric search for giant planets and brown dwarfs around a sample of ~30 M-dwarfs. We have discovered several low-mass companion…
Speckle Decorrelation and Dynamic Range in Speckle Noise Limited Imaging
Anand Sivaramakrishnan, James P. Lloyd, Philip E. Hodge +1
The useful dynamic range of an image in the diffraction limited regime is usually limited by speckles caused by residual phase errors in the optical system forming the image. The t…
An Adaptive Optics Survey for Companions to Stars with Extra-Solar Planets
J. P. Lloyd, M. C. Liu, J. R. Graham +12
We have undertaken an adaptive optics (AO) imaging survey of extrasolar planetary systems and stars showing interesting radial velocity trends from high precision radial velocity s…
