Wavelets: a powerful tool for studying rotation, activity, and pulsation in Kepler and CoRoT stellar light curves

JP Bravo, S Roque, R Estrela, IC Leão… - Astronomy & …, 2014 - aanda.org
Aims. The wavelet transform has been used as a powerful tool for treating several problems
in astrophysics. In this work, we show that the time–frequency analysis of stellar light curves …

Orbital parameters of the eclipsing detached Kepler binaries with eccentric orbits

D Kjurkchieva, D Vasileva… - The Astronomical …, 2017 - iopscience.iop.org
We present precise values of the eccentricity and periastron angle of 529 detached,
eccentric, eclipsing stars from the Kepler Eclipsing Binary catalog that were determined by …

Light curve solutions of the ultrashort‐period Kepler binaries

D Kjurkchieva, D Dimitrov - Astronomische Nachrichten, 2015 - Wiley Online Library
We carried out light‐curve solutions of the ultrashort‐period binaries with MS components
observed by Kepler. All six targets turned out almost in thermal contact with contact or …

Light curve solutions of the eclipsing Kepler binaries KIC 5080652, KIC 5285607, KIC 9236858 and KIC 11975363

D Kjurkchieva, T Atanasova - New Astronomy, 2016 - Elsevier
We carried out light curve solutions of four detached binaries with circular orbits, observed
by Kepler. As a result their orbital inclinations, temperatures and relative stellar radii were …

Light‐curve solutions of 20 ecipsing Kepler binaries, most of them with pronounced spot and flare activity

D Kjurkchieva, T Atanasova… - Astronomische …, 2016 - Wiley Online Library
We carried out light curve solutions of the Kepler light curves of twenty detached eclipsing
binaries with circular orbits and determined the orbital inclinations, temperatures. relative …
