Multiperiodicity, modulations, and flip-flops in variable star light curves
Aims. We study LQ Hya photometry for 1982–2014 with the carrier fit (CF) method and compare our results to earlier photometric analysis and recent Doppler imaging maps. Methods. As the rotation period of the object is not known a priori, we utilize different types of statistical methods first (least-squares fit of harmonics, phase dispersion statistics) to estimate various candidates for the ca...
متن کاملFinding outlier light-curves in catalogs of periodic variable stars
We present a methodology to discover outliers in catalogs of periodic light-curves. We use cross-correlation as measure of “similarity” between two individual light-curves and then classify light-curves with lowest average “similarity” as outliers. We performed the analysis on catalogs of variable stars of known type from the MACHO and OGLE projects and established that our method correctly ide...
متن کاملLuminous Red Variable Star
We report photometry and spectroscopy of the evolution of Nova Sagittarii 1994 #1 (V4332 Sagittarii) during outburst. We compare the photometric and spectral evolution of this outburst to known classes of outbursts – including classical novae and outbursts occurring on symbiotic stars – and find this object does not conform to any known class of outburst. The closest match to the behavior of th...
متن کاملThe pulsed X - ray light curves of the isolated neutron star RBS 1223 ⋆
We present multi-epoch spectral and timing analysis of the isolated neutron star RBS1223. New XMM-Newton data obtained in January 2004 confirm the spin period to be twice as long as previously thought, P spin = 10.31 s. The combined ROSAT, Chandra, XMM-Newton data (6 epochs) give, contrary to earlier findings, no clear indication of a spin evolution of the neutron star. The X-ray light curves a...
متن کاملA Completely Integrable Flow of Star-shaped Curves on the Light Cone in Lorentzian R
In this paper we prove that the space of differential invariants for curves with arc-length parameter in the light cone of Lorentzian R4, invariants under the centro-affine action of the Lorentzian group, is Poisson equivalent to the space of conformal differential invariants for curves in the Möbius sphere. We use this relation to find realizations of solutions of a complexly coupled system of...
