Discovery of Five Very Low Mass Close Binaries, Resolved in the Visible with Lucky Imaging
N. M. Law, S. T. Hodgkin, C. D. Mackay
We survey a sample of 32 M5-M8 stars with distance < 40pc for companions with separations between 0.1 arcsec and 1.5 arcsec and with Delta m_i <5. We find five new VLM binaries wit…

Photon counting strategies with low light level CCDs
A. G. Basden, C. A. Haniff, C. D. Mackay
Low light level charge coupled devices (L3CCDs) have recently been developed, incorporating on-chip gain. They may be operated to give an effective readout noise much less than one…
