Comparison of damped oscillations in solar and stellar X-ray flares

IH Cho, KS Cho, VM Nakariakov, S Kim… - The Astrophysical …, 2016 - iopscience.iop.org
We explore the similarity and difference of the quasi-periodic pulsations (QPPs) observed in
the decay phase of solar and stellar flares at X-rays. We identified 42 solar flares with …
