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