Circular polarization survey of intermediate polars I. Northern targets in the range 17h<R.A.<23h
O. W. Butters, S. Katajainen, A. J. Norton +2
Context. The origin, evolution, and ultimate fate of magnetic cataclysmic variables are poorly understood. It is largely the nature of the magnetic fields in these systems that lea…
HS0139+0559, HS0229+8016, HS0506+7725 and HS0642+5049: Four new long-period cataclysmic variables
A. Aungwerojwit, B. T. Gaensicke, P. Rodriguez-Gil +9
We present time-resolved optical spectroscopy and photometry of four relatively bright (V~14.0-15.5) long-period cataclysmic variables (CVs) discovered in the Hamburg Quasar Survey…
UBVRI photopolarimetry of the long period eclipsing AM Herculis binary V1309
S. Katajainen, V. Piirola, G. Ramsay +6
We report simultaneous UBVRI photo-polarimetric observations of the long period (7.98 h) AM Her binary V1309 Ori. The length and shape of the eclipse ingress and egress varies from…
Pulsations and orbital modulation of the intermediate polar 1WGA J1958.2+3232
A. J. Norton, H. Quaintrell, S. Katajainen +3
We present optical photometry, spectroscopy and photopolarimetry, as well as ASCA X-ray observations, of the recently discovered intermediate polar 1WGA J1958.2+3232. Through the f…
Constraints on the optical afterglow emission of the short/hard burst GRB 010119
J. Gorosabel, M. I. Andersen, J. Hjorth +7
We report optical observations of the short/hard burst GRB 010119 error box, one of the smallest error boxes reported to date for short/hard GRBs. Limits of R > 22.3 and I > 21.2 a…
Day-Scale Variability of 3C 279 and Searches for Correlations in Gamma-Ray, X-Ray, and Optical Bands
R. C. Hartman, M. Villata, T. J. Balonek +36
Light curves of 3C 279 are presented in optical (R-band), X-rays (RXTE/PCA), and gamma rays (CGRO/EGRET) for 1999 Jan-Feb and 2000 Jan-Mar. During both of those epochs the gamma-ra…
