The long-period Galactic Cepheid RS Puppis - III. A geometric distance from HST polarimetric imaging of its light echoes
P. Kervella, H. E. Bond, M. Cracraft +8
As one of the most luminous Cepheids in the Milky Way, the 41.5-day RS Puppis is an analog of the long-period Cepheids used to measure extragalactic distances. An accurate distance…
The long-period Galactic Cepheid RS Puppis - II. 3D structure and mass of the nebula from VLT/FORS polarimetry
P. Kervella, A. Mérand, L. Szabados +7
The long-period Cepheid RS Pup is surrounded by a large dusty nebula reflecting the light from the central star. Due to the changing luminosity of the central source, light echoes…
The effect of metallicity on Cepheid magnitudes and the distance to M33
V. Scowcroft, D. Bersier, J. R. Mould +1
We present the results from a multi-epoch survey of two regions of M33 using the 3.5m WIYN telescope. The inner field is located close to the centre of the galaxy, with the outer r…
Cepheid distances from Interferometry
Pierre Kervella
Long baseline interferometry is now able to resolve the pulsational change of the angular diameter of a significant number of Cepheids in the solar neighborhood. This allows the ap…
Using Cepheids to determine the galactic abundance gradient I. The solar neighbourhood
S. M. Andrievsky, V. V. Kovtyukh, R. E. Luck +7
A number of studies of abundance gradients in the galactic disk have been performed in recent years. The results obtained are rather disparate: from no detectable gradient to a rat…
Using Cepheids to determine the galactic abundance gradient II. Towards the galactic center
S. M. Andrievsky, D. Bersier, V. V. Kovtyukh +4
Based on spectra obtained at the Anglo-Australian Observatory, we present a discussion of the metallicity of the galactic disc derived using Cepheids at galactocentric distances 4-…
Variable Stars in the Fornax Dwarf Galaxy
D. Bersier, P. R. Wood
We present a search for variable stars in the Fornax dwarf galaxy covering an area of 1/2 a square degree. We have ~30 epochs of VI data. We found and determined periods for more t…
