  • A Combined Analysis of the ... A Combined Analysis of the Observational Aspects of the Quasi-biennial Oscillation in Solar Magnetic Activity
    Bazilevskaya, G.; Broomhall, A.-M.; Elsworth, Y. ... Space science reviews, 12/2014, Letnik: 186, Številka: 1-4
    Journal Article
    Recenzirano

    Solar quasi-biennial oscillations (QBOs) with the time scale of 0.6–4 yrs appear to be a basic feature of the Sun’s activity. Observational aspects of QBOs are reviewed on the basis of recent ...

  • Oscillations in stellar sup... Oscillations in stellar superflares
    Balona, L. A; Broomhall, A.-M; Kosovichev, A ... Monthly notices of the Royal Astronomical Society, 06/2015, Letnik: 450, Številka: 1
    Journal Article
    Recenzirano
    Odprti dostop

    Two different mechanisms may act to induce quasi-periodic pulsations (QPP) in whole-disc observations of stellar flares. One mechanism may be magnetohydromagnetic forces and other processes acting on ...

  • Statistical properties of q... Statistical properties of quasi-periodic pulsations in white-light flares observed with Kepler
    Pugh, C. E; Armstrong, D. J; Nakariakov, V. M ... Monthly notices of the Royal Astronomical Society, 07/2016, Letnik: 459, Številka: 4
    Journal Article
    Recenzirano
    Odprti dostop

    We embark on a study of quasi-periodic pulsations (QPPs) in the decay phase of white-light stellar flares observed by Kepler. Out of the 1439 flares on 216 different stars detected in the ...

  • The Octave (Birmingham–Shef... The Octave (Birmingham–Sheffield Hallam) automated pipeline for extracting oscillation parameters of solar-like main-sequence stars
    Hekker, S.; Broomhall, A.-M.; Chaplin, W. J. ... Monthly notices of the Royal Astronomical Society, March 2010, Letnik: 402, Številka: 3
    Journal Article
    Recenzirano
    Odprti dostop

    The number of main-sequence stars for which we can observe solar-like oscillations is expected to increase considerably with the short-cadence high-precision photometric observations from the NASA ...

  • Significance testing for qu... Significance testing for quasi-periodic pulsations in solar and stellar flares
    Pugh, C. E.; Broomhall, A.-M.; Nakariakov, V. M. Astronomy and astrophysics (Berlin), 06/2017, Letnik: 602
    Journal Article
    Recenzirano
    Odprti dostop

    The robust detection of quasi-periodic pulsations (QPPs) in solar and stellar flares has been the topic of recent debate. In light of this, we have adapted a method described by Vaughan (2005, A&A, ...

  • A Helioseismic Perspective ... A Helioseismic Perspective on the Depth of the Minimum Between Solar Cycles 23 and 24
    Broomhall, A.-M. Solar physics, 04/2017, Letnik: 292, Številka: 4
    Journal Article
    Recenzirano
    Odprti dostop

    The minimum in the solar-activity cycle observed between Cycles 23 and 24 is generally regarded as being unusually deep and long. This minimum is being followed by a cycle with one of the smallest ...

  • A Comparison Between Global... A Comparison Between Global Proxies of the Sun’s Magnetic Activity Cycle: Inferences from Helioseismology
    Broomhall, A.-M.; Nakariakov, V. M. Solar physics, 11/2015, Letnik: 290, Številka: 11
    Journal Article
    Recenzirano
    Odprti dostop

    The last solar minimum was, by recent standards, unusually deep and long. We are now close to the maximum of the subsequent solar cycle, which is relatively weak. In this article we make comparisons ...

    Pugh, C. E.; Broomhall, A.-M.; Nakariakov, V. M. Astronomy and astrophysics (Berlin), 04/2019, Letnik: 624
    Journal Article
    Recenzirano
    Odprti dostop

    Context. Quasi-periodic pulsations (QPPs) are a common feature of solar flares, but there has previously been a lack of observational evidence to support any of the theoretical models that might ...

    Pugh, C. E.; Nakariakov, V. M.; Broomhall, A.-M. ... Astronomy and astrophysics (Berlin), 12/2017, Letnik: 608
    Journal Article
    Recenzirano
    Odprti dostop

    Context. Quasi-periodic pulsations (QPPs) are a common feature of solar and stellar flares, and so the nature of these pulsations should be understood in order to fully understand flares. Aims. We ...

    Pascoe, D. J.; Smyrli, A.; Van Doorsselaere, T. ... The Astrophysical journal, 12/2020, Letnik: 905, Številka: 1
    Journal Article
    Recenzirano
    Odprti dostop

    Quasi-periodic pulsations (QPPs) are routinely observed in a range of wavelengths during flares, but in most cases the mechanism responsible is unknown. We present a method to detect and characterize ...
