An Imaging Survey for Extrasolar Planets around 45 Close, Young Stars with SDI at the VLT and MMT
Beth A. Biller, Laird M. Close, Elena Masciadri +11
We present the results of a survey of 45 young (<250 Myr), close (<50 pc) stars with the Simultaneous Differential Imager (SDI) implemented at the VLT and the MMT for the direct de…
A Survey of Close, Young Stars with the Simultaneous Differential Imager (SDI) at the VLT and MMT
Beth A. Biller, Laird M. Close, Elena Masciadri +6
We discuss the preliminary results of a survey of young (<300 Myr), close (<50 pc) stars with the Simultaneous Differential Extrasolar Planet Imager (SDI) implemented at the VLT an…
Suppressing Speckle Noise for Simultaneous Differential Extrasolar Planet Imaging (SDI) at the VLT and MMT
Beth A. Biller, Laird M. Close, Rainer Lenzen +5
We discuss the instrumental and data reduction techniques used to suppress speckle noise with the Simultaneous Differential Imager (SDI) implemented at the VLT and the MMT. SDI use…
High Resolution Images of Orbital Motion in the Trapezium Cluster: First Scientific Results from the MMT Deformable Secondary Mirror Adaptive Optics System
Laird M. Close, Francois Wildi, Michael Lloyd-Hart +16
We present the first scientific images obtained with a deformable secondary mirror adaptive optics system. We utilized the 6.5m MMT AO system to produce high-resolution (FWHM=0.07'…
