Space reddenings are derived for 15 Galactic Cepheids from dereddening CCD BVRIc data for AF-type stars in the immediate vicinities of the variables, in conjunction with 2MASS reddenings for BAF-type ...
Galactic Cepheids with Spitzer: II. Search for Extended Infrared Emission
Cepheids — infrared stars — stars mass loss
2010/11/16
A deep and detailed examination of 29 classical Cepheids with the Spitzer Space Telescope has revealed three stars with strong nearby extended emission detected in multiple bands which appears to be p...
Classical Cepheids: Yet another version of the Baade-Becker-Wesselink method
Cepheids luminosities radii color excess
2010/11/16
We propose a new version of the Baade–Becker–Wesselink technique, which allows one to independently determine the colour excess and the intrinsic colour of a radially pulsating star, in addition to it...
PR AND PL (PMV) RELATIONS FOR CLASSICAL CEPHEIDS REVISITED
Cepheids Stars: distances Stars: statistics
2010/10/29
Using observational data available for a large number of Galactic Cepheids, we determine the relation between the radius and the period of pulsations, by means of a variant of the Baade{Wesselink meth...
