The Metallicity dependence of the Cepheid Period-Luminosity relation: methodology and results
Marta Mottini, Martino Romaniello, Francesca Primas +3
We present the results of an observational campaign undertaken to assess the influence of the iron content on the Cepheid Period-Luminosity relation. Our data indicate that this de…
A purely geometric distance to the binary star Atlas, a member of the Pleiades
N. Zwahlen, P. North, Y. Debernardi +4
We present radial velocity and new interferometric measurements of the double star Atlas, which permit, with the addition of published interferometric data, to precisely derive the…
AGB stars in the Local Group, and beyond
Martin Groenewegen
I summarize the current status of surveys for late-type M, and Carbon stars in the Local Group based on three different approaches that make use of the characteristics of these sta…
Improved Baade-Wesselink surface-brightness relations
Martin Groenewegen
Recent, and older accurate, data on (limb-darkened) angular diameters is compiled for 221 stars, as well as BVRIJK[12][25] magnitudes for those objects, when available. Nine stars…
Long Period Variables in the Magellanic Clouds: OGLE + 2MASS + DENIS
Martin Groenewegen
(abridged) The 68000 I-band light curves of variable stars detected by the OGLE survey in the Large and Small Magellanic Clouds (MCs) are fitted by Fourier series, and also correla…
Evolution of planetary nebulae II. Population effects on the bright cut-off of the PNLF
P. Marigo, L. Girardi, A. Weiss +2
We investigate the bright cut-off of the [OIII]l5007 planetary nebula luminosity function (PNLF), that has been suggested as a powerful extragalactic distance indicator. Theoretica…
