An O−C (and light travel time) method suitable for application to large photometric databases
(Oxford University Press, 2014)
The standard method of studying period changes in variable stars is to study the timing
residuals or O−C values of light-curve maxima or minima. The advent of photometric surveys
for variability, covering large parts of ...
Multicolour time series photometry of the variable star 1SWASP J234401.81−212229.1
(Oxford University Press, 2014)
1SWASP J234401.81-212229.1 may be one of a handful of contact binaries comprising two
Mdwarfs. Modelling of the available observations is complicated by the fact that the radiation
of the eclipsing system is dominated ...
A search for p-mode pulsations in white dwarf stars using the Berkeley Visible Imaging Tube detector
(Oxford University Press, 2014)
We present high-speed photometry (resolution 0.1 s) obtained during the commissioning of the
Berkely Visible Imaging Tube system on the Southern African Large Telescope (SALT). The
observations were an attempt to search ...
Causes and patterns of morbidity and mortality in Afghanistan: Joint estimation of multiple causes in the neonatal period
(Springer, 2014)
This paper focuses on investigating the leading cause(s) of death and preventable factors in Afghanistan,
using data from verbal autopsies of infant deaths. We are of the view that the presence
of a disease in a person ...
