Photometrically simply behaving mCP stars
Z. Mikulasek, T. Graf, J. Krticka +2
We analyzed uvby and Hp light curves of 19 well observed magnetic CP stars selected from the "On-line database of photometric observations of mCP stars" of which light curves in al…
The record-breaking rotational braking of the He strong CP star HD 37776
Z. Mikulasek, J. Krticka, J. Zverko +8
We study the long-term light and spectral variations in the He-strong magnetic chemically peculiar star HD 37776 (V901 Ori) to search for changes of its 1.5387 d period in 1976-200…
The benefits of the orthogonal LSM models
Z. Mikulasek
In the last few decades both the volume of high-quality observing data on variable stars and common access to them have boomed; however the standard used methods of data processing…
The light variability of the helium strong star HD 37776 as a result of its inhomogeneous elemental surface distribution
J. Krticka, Z. Mikulasek, J. Zverko +1
We simulate light curves of the helium strong chemically peculiar star HD 37776 assuming that the observed periodic light variations originate as a result of inhomogeneous horizont…
The ZOO of uvby and Hp light curves of magnetic chemically peculiar stars
Z. Mikulasek, J. Zverko, J. Krticka +3
We present preliminary results of the generalized Principal Component Analysis (PCA) of light curves of 82 magnetic chemically peculiar (further mCP) stars applied to 54 thousand i…
The light variations of HD 37776 as a result of the uneven surface distribution of helium and silicon
Jiri Krticka, Zdenek Mikulasek, Juraj Zverko +1
We calculate the uvby light curves of the helium-strong chemically peculiar (CP) star HD 37776. Assuming that the chemical peculiarity influences the monochromatic radiative flux d…
Principal component analysis - an efficient tool for variable stars diagnostics
Zdenek Mikulasek
We present two diagnostic methods based on ideas of Principal Component Analysis and demonstrate their efficiency for sophisticated processing of multicolour photometric observatio…
