DESCRIPTION:Speakers: Isak Delberth Davids (North-West University\, Potche
 fstroom Campus)\nWith the birth of the new generation ground-based gamma-r
 ay imaging atmospheric Cherenkov telescope arrays (such as H.E.S.S.\, MAGI
 C and VERITAS)\, there is a growing need to probe X-ray binary stars for v
 ery high energy gamma-ray emissions. Since the discovery of the first extr
 a-solar X-ray binary (XRB)\, namely the Scorpius X-1 in 1962\, XRBs are no
 w well-established systems in the realm of X-ray astronomy. Today Scorpius
  X-1\, with X-ray output energy 100 000 times greater than the total radia
 tion of the Sun at all wavelengths\, is today known as a microquasar. In o
 rder to foster the multi-wavelength campaigns of the day\, we selected can
 didate XRBs from the Galaxy that were observed by H.E.S.S. for purposes of
  searching for significant TeV gamma-ray emission from these. Paredes (200
 8) confirmed four XRBs to be candidates that can be listed on the gamma-ra
 y sky map. These were PSR B1259-63\, LS I +61 303\, LS 5039 and Cygnus X-1
 . From a survey of 125 known XRBs\, Dickinson (2009) reported no conclusiv
 e detections of TeV emissions. The present study presents the Cherenkov te
 chnique\, a briefing on X-ray binaries\, known radiation mechanisms\, rele
 vant analysis techniques\, and report on the preliminary results of Galact
 ic XRBs that do not add any of the candidate XRBs to the envisaged catalog
 ue of TeV gamma-ray binaries. It is an astrophysical hope that the envisag
 ed CTA (Cherenkov Telescope Array)\, which may be hosted by South Africa\,
  will provide the anticipated discoveries\, providing a deep insight of th
 e TeV gamma-ray sky.\n\nhttps://events.saip.org.za/event/7/contributions/5
