The Luminosities and Distance Scales of Type II Cepheid and RR Lyrae variables
Michael W. Feast, Cliford D. Laney, Thomas D. Kinman +2
Infrared and optical absolute magnitudes are derived for the type II Cepheids kappa Pav and VY Pyx from revised Hipparcos parallaxes and for kappa Pav, V553 Cen and SW Tau from pul…
A spectral atlas of post-main-sequence stars in omega Centauri: kinematics, evolution, enrichment and interstellar medium
Jacco Th. van Loon, Floor van Leeuwen, Barry Smalley +4
We present a spectral atlas of the post-main-sequence population of the most massive Galactic globular cluster, omega Centauri. Spectra were obtained of more than 1500 stars select…
Cepheid Parallaxes and the Hubble Constant
Floor van Leeuwen, Michael W. Feast, Patricia A. Whitelock +1
Revised Hipparcos parallaxes for classical Cepheids are analysed together with 10 HST-based parallaxes (Benedict et al.). In a reddening-free V,I relation we find that the coeffici…
Semi-Regular Variables in the Solar Neighbourhood
I. S. Glass, F. van Leeuwen
Period-luminosity sequences have been shown to exist among the Semi-Regular Variables (SRVs) in the Magellanic Clouds (Wood et al, 1999), the Bulge of the Milky Way galaxy (Glass &…
The Geometric Calibration of the Planck satellite using Solar System Objects
D. L. Harrison, F. van Leeuwen
The geometric calibration of the Planck satellite using the planetary transits is investigated, together with the reconstruction of any offsets from the nominal layout of the focal…
The Geometric Calibration of the Planck satellite using point-source observations
D. L. Harrison, F. van Leeuwen
The geometric calibration of the Planck satellite is investigated, specifically those parameters which require the use of the science data for their extraction. Methods for the rec…
