On the nature of the variable star UNSW-V-760
(Oxford University Press, 2011)
The results of multicolour photometric monitoring over several nights of the probable X-ray
source UNSW-V-760 are presented. Drawing on both present and past observations, it is
shown that the star is multiperiodic and ...
Two large amplitude slowly pulsating hot subdwarf stars
(Oxford University Press, 2011)
The discovery observations of two new slowly pulsating subdwarf B stars (V1093 Her stars),
BPS CS22890−74 and PB 7032, are presented. Both stars are highly multiperiodic, and have –
for V1093 Her stars – large amplitudes. ...
Time series photometry of the nearby brown dwarf DENIS-P J0041353-562112
(Oxford University Press, 2011)
DENIS-P J0041353−562112 is a brown dwarf, with a spectral type of M7.5, which may be
younger than 20 Myr. On the basis of its Hα emission-line asymmetry, it has been suggested
that the object is accreting material. If ...
UBV(RI)C photometry of transiting planet hosting stars
(Oxford University Press, 2011)
We present new UBV(RI)C photometry of 22 stars that host transiting planets, 19 of which
were discovered by the Wide Angle Search for Planets (WASP) survey. We use these data
together with Two Micron All Sky Survey (2MASS) ...
