Cepheid distances from the SpectroPhoto-Interferometry of Pulsating Stars \(SPIPS\)
Context. The parallax of pulsation, and its implementations such as the Baade-Wesselink method and the infrared surface brightness technique, is an elegant method to determine distances of pulsating stars in a quasi-geometrical way. However, these classical implementations in general only use a subset of the available observational data. Aims. Freedman & Madore (2010, ApJ, 719, 335) suggested a...
متن کاملCepheid distances from Interferometry
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 application of a new version of the Baade-Wesselink (BW) method to measure their distance, for which we do not need to estimate the star’s temperature. Using angular diameter measurements from the VLT Interferometer, we...
متن کاملCepheid distances from infrared long-baseline interferometry
Using our interferometric angular diameter measurements of seven classical Cepheids reported in Kervella et al. (2003, Paper I), complemented by previously existing measurements, we derive new calibrations of the Cepheids Period–Radius (P–R) and Period–Luminosity (P–L) relations. We obtain a P–R relation of logR = [0.767 ± 0.009] logP + [1.091 ± 0.011], only 1σ away from the relation obtained b...

متن کاملObservations of Pulsating Stars
Pulsations discussed will begin at the “top” of the instability strip with pulsating red giants and Miras, which are evolved stars nearing their own demise. The next discussed will be the Cepheids, both the “Classical” ones as well as the W Virginis (Population II stars). While moving down the instability strip of the HR Diagram, the next major type of variable (pulsating) star are the RR Lyrae...
