Classical Cepheid Pulsation Models. X. The Period-Age Relation

G. Bono, M. Marconi, S. Cassisi +3

We present new Period-Age (PA) and Period-Age-Color (PAC) relations for fundamental and first overtone classical Cepheids. Current predictions rely on homogeneous sets of evolution…

The Araucaria Project. The Distance to the Local Group Galaxy NGC 6822 from Cepheid Variables discovered in a Wide-Field Imaging Survey

G. Pietrzynski, W. Gieren, A. Udalski +5

We have obtained mosaic images of NGC 6822 in V and I bands on 77 nights. From these data, we have conducted an extensive search for Cepheid variables over the entire field of the…

The Araucaria Project. An improved distance to the Sculptor spiral galaxy NGC 300 from its Cepheid variables

W. Gieren, G. Pietrzynski, A. Walker +8

In a previous paper, we reported on the discovery of more than a hundred new Cepheid variables in the Sculptor Group spiral NGC 300 from wide-field images taken in the B and V phot…

A transiting extrasolar giant planet around the star OGLE-TR-113

Maciej Konacki, Guillermo Torres, Dimitar D. Sasselov +6

We report the independent discovery of a new extrasolar transiting planet around OGLE-TR-113, a candidate star from the Optical Gravitational Lensing Experiment. Small radial-veloc…

The angular size of the Cepheid L Car: a comparison of the interferometric and surface brightness techniques

P. Kervella, P. Fouque, J. Storm +5

Recent interferometric observations of the brightest and angularly largest classical Cepheid, L Carinae, with ESO's VLT Interferometer (VLTI) have resolved with high precision the…

The effect of metallicity on the Cepheid Period-Luminosity relation from a Baade-Wesselink analysis of Cepheids in the Galaxy and in the Small Magellanic Cloud

Jesper Storm, Bruce W. Carney, Wolfgang P. Gieren +3

(ABRIDGED) We have applied the near-IR Barnes-Evans realization of the Baade-Wesselink method as calibrated by Fouque & Gieren (1997) to five metal-poor Cepheids with periods betwe…
