    • Dark spot, spiral waves and the sw sextantis behaviour: it is all about ux ursae majoris 

      Neustroev, V. V.; Suleimanov, V. F.; Borisov, N. V.; Belyakov, K. V.; Shearer, A. (Oxford University Press (OUP), 2010-10-12)
      We present an analysis of time-resolved, medium-resolution optical spectroscopic observations of UX Ursae Majoris (UX UMa) in the blue (3920-5250 A) and red (6100-7200 A) wavelength ranges that were obtained in 1999 April ...
    • Ptf1 j191905.19+481506.2—a partially eclipsing am cvn system discovered in the palomar transient factory 

      Levitan, David; Kupfer, Thomas; Groot, Paul J.; Margon, Bruce; Prince, Thomas A.; Kulkarni, Shrinivas R.; Hallinan, Gregg; Harding, Leon K.; Kyne, Gillian; Laher, Russ; Ofek, Eran O.; Rutten, René G. M.; Sesar, Branimir; Surace, Jason (IOP Publishing, 2014-04-02)
      We report on PTF1 J191905.19+ 481506.2, a newly discovered, partially eclipsing, outbursting AM CVn system found in the Palomar Transient Factory synoptic survey. This is only the second known eclipsing AM CVn system. We ...
    • Spin-orbit alignment in the very low mass binary regime 

      Harding, L. K.; Hallinan, G.; Konopacky, Q. M.; Kratter, K. M.; Boyle, R. P.; Butler, R. F.; Golden, A. (EDP Sciences, 2013-06-01)
      Studies of solar-type binaries have found coplanarity between the equatorial and orbital planes of systems with < 40 AU separation. By comparison, the alignment of the equatorial and orbital axes in the substellar ...
    • Veritas observations of the microquasar cygnus x-3

L.; ,; , (IOP Publishing, 2013-12-03)
      We report results from TeV gamma-ray observations of the microquasar Cygnus X-3. The observations were made with the Very Energetic Radiation Imaging Telescope Array System (VERITAS) over a time period from 2007 June 11 ...
