THE EFFECT OF LINE BLOCKING ON THE LIGHT CURVES OF THE AP STAR HR 5355 (HD 125248).

@article{Pilachowski1975THEEO,  title={THE EFFECT OF LINE BLOCKING ON THE LIGHT CURVES OF THE AP STAR HR 5355 (HD 125248).},  author={Catherine A. Pilachowski and Walter K. Bonsack},  journal={Publications of the Astronomical Society of the Pacific},  year={1975},  volume={87},  pages={221 - 229},  url={https://api.semanticscholar.org/CorpusID:122505963}}
Line-blocking coefficients were measured from coude spectrograms covering the blue and green parts of the spectra, throughout the 9d3 cycle of HR 5355. The coefficient for the V band of the uvby photometry is found to vary through a range of 0" 06 of the continuum in a double wave, with maxima corresponding to the maxima of both the Eu ii and the Cr spectrum variation, which occur in antiphase. This line blocking cannot account for the strong single-wave light variation in the V band, which has…

Photometric investigations of several early-type variable stars using the stereo satellite

We present results from high-precision photometric monitoring of several bright early-type stars. The data cover five years and are collected by the STEREO satellite. Stellar types covered are a…

Photometric Variability of the mCP Star CS Vir: Evolution of the Rotation Period

Abstract The aim of this study is to accurately calculate the rotational period of CS Vir by using STEREO observations and investigate a possible period variation of the star with the help of all…

The Magnetic Variable Stars

The peculiar A stars were first noted as peculiar because they exhibit anomalously strong lines of one or more of the elements Si, Cr, Mn, Sr, and Eu. These diverse objects are all called Ap stars…
