Time series models of three sets of RXTE Observations of 4U 1543-47
(Oxford University Press, 2013)The X-ray nova 4U 1543−47 was in a different physical state (low/hard, high/soft, and very high) during the acquisition of each of the three time series analyzed in this paper. Standard time series models of the ... -
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 ... -
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. ... -
Two new variable sdB stars, HE 0218−3437 and LB 1516
(Oxford University Press, 2010)We present photometry which shows that two known hot subdwarf stars, HE 0218−3437 and LB 1516, are variable. LB 1516 exhibits several frequencies in the range 12–25 cycles d−1 (periods of about 1–2 h) with amplitudes ... -
UBV(RI)C JHK observations of Hipparcos-selected nearby stars
(Oxford University Press, 2010)We present homogeneous, standardized UBV(RI)C photometry for over 700 nearby stars selected on the basis of Hipparcos parallaxes. Additionally, we list JHK photometry for about half of these stars, as well as L photometry ... -
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) ... -
What can be deduced from open cluster metallicity measurements?
(Oxford University Press, 2007)The dependence of [Fe/H] on galactocentric distance, distance from the galactic mid-plane and age is studied. Both ordinary least-squares and non-parametric regression in the form of a ‘generalized additive model’ are ...
