On multiple classes of gamma-ray bursts, as deduced from autocorrelation functions or bivariate duration/hardness ratio distributions
(Oxford University Press, 2012)
Autocorrelation functions (ACFs) of 119 gamma-ray bursts (GRBs) monitored by the Burst
Alert Telescope (BAT) on Swift are calculated. Contrasting with previous results for smaller
numbers of bursts from other missions, ...
Estimation of the coherence time of stochastic oscillations from modest samples
(Oxford University Press, 2012)
‘Quasi-periodic’ or ‘solar-like’ oscillations can be described by three parameters – a characteristic
frequency, a coherence time (or ‘quality factor’) and the variance of the random
driving process. This paper is concerned ...
More on the nature of the variable star UNSW-V-760
(Oxford University Press, 2012)
The results of two multicolour time-series photometric observing runs, separated by about two
months, are presented. The same periodicities previously detected in photometry of UNSWV-
760 are still present, albeit at ...
Detection of an increasing orbital period in the subdwarf B eclipsing system NSVS 14256825
(Oxford University Press, 2012)
New timings of eclipses made in 2010 and 2011 are presented for the hot subdwarf B (sdB)
eclipsing binary NSVS 14256825. Composed of an sdB star and a much cooler companion,
with a period near 0.1104 days, this system ...
