Abstract:
We present the results of a multiwavelength (far-ultraviolet to I
band) survey of the stellar populations of the globular cluster
NGC 6752, using Space Telescope Imaging Spectrograph (STIS, FUV,
2001/03/01), Advanced Camera for Surveys (ACS, VI on 2006/06/24) and
Wide Field Camera 3 (WFC3, NUV on 2010/07/31, 2010/08/07 and
2010/08/21, and UB on 2010/05/1-5) on board the Hubble Space
Telescope. We have confirmed that two previously identified
cataclysmic variable (CV) candidates are, in fact, dwarf novae which
underwent outbursts during our observations. We have also identified
previously unknown optical counterparts to two X-ray sources.
