  • Projected spin–orbit alignm... Projected spin–orbit alignments from Kepler asteroseismology and Gaia astrometry
    Ball, Warrick H; Triaud, Amaury H M J; Hatt, Emily ... Monthly Notices of the Royal Astronomical Society Letters, 06/2023, Letnik: 521, Številka: 1
    Journal Article
    Recenzirano
    Odprti dostop

    ABSTRACT The angle between the rotation and orbital axes of stars in binary systems – the obliquity – is an important indicator of how these systems form and evolve, but few such measurements exist. ...

  • Prospects for Galactic and ... Prospects for Galactic and stellar astrophysics with asteroseismology of giant stars in the TESS continuous viewing zones and beyond
    Mackereth, J Ted; Miglio, Andrea; Elsworth, Yvonne ... Monthly Notices of the Royal Astronomical Society, 04/2021, Letnik: 502, Številka: 2
    Journal Article
    Recenzirano
    Odprti dostop

    ABSTRACT The NASA Transiting Exoplanet Survey Satellite (NASA-TESS) mission presents a treasure trove for understanding the stars it observes and the Milky Way, in which they reside. We present a ...

  • Stellar models with calibra... Stellar models with calibrated convection and temperature stratification from 3D hydrodynamics simulations
    Mosumgaard, Jakob Rørsted; Ball, Warrick H; Silva Aguirre, Víctor ... Monthly Notices of the Royal Astronomical Society, 08/2018, Letnik: 478, Številka: 4
    Journal Article
    Recenzirano
    Odprti dostop

    ABSTRACT Stellar evolution codes play a major role in present-day astrophysics, yet they share common simplifications related to the outer layers of stars. We seek to improve on this by the use of ...

  • Surface effects in solar-li... Surface effects in solar-like oscillators
    Ball, Warrick H. EPJ Web of Conferences, 01/2017, Letnik: 160
    Journal Article, Conference Proceeding
    Recenzirano
    Odprti dostop

    Inaccurate modelling of the near-surface layers of solar models causes a systematic difference between modelled and observed solar mode frequencies. This difference—known as the “surface effect” or ...

  • Magnetic and Rotational Evo... Magnetic and Rotational Evolution of ρ CrB from Asteroseismology with TESS
    Metcalfe, Travis S.; van Saders, Jennifer L.; Basu, Sarbani ... Astrophysical journal/˜The œAstrophysical journal, 11/2021, Letnik: 921, Številka: 2
    Journal Article
    Recenzirano
    Odprti dostop

    Abstract During the first half of main-sequence lifetimes, the evolution of rotation and magnetic activity in solar-type stars appears to be strongly coupled. Recent observations suggest that ...

  • Solar cycle variation of νm... Solar cycle variation of νmax in helioseismic data and its implications for asteroseismology
    Howe, Rachel; Chaplin, William J; Basu, Sarbani ... Monthly Notices of the Royal Astronomical Society Letters, 03/2020, Letnik: 493, Številka: 1
    Journal Article
    Odprti dostop

    ABSTRACT The frequency, νmax, at which the envelope of pulsation power peaks for solar-like oscillators is an important quantity in asteroseismology. We measure νmax for the Sun using 25 yr of ...

    Chontos, Ashley; Huber, Daniel; Berger, Travis A. ... Astrophysical journal/˜The œAstrophysical journal, 12/2021, Letnik: 922, Številka: 2
    Journal Article
    Recenzirano

  • Solar-like oscillations and... Solar-like oscillations and ellipsoidal variations in TESS observations of the binary 12 Boötis
    Ball, Warrick H; Miglio, Andrea; Chaplin, William J ... Monthly Notices of the Royal Astronomical Society, 09/2022, Letnik: 516, Številka: 3
    Journal Article
    Recenzirano

    Ball, Warrick H; Tout, Christopher A; Żytkow, Anna N Monthly Notices of the Royal Astronomical Society, April 2012, Letnik: 421, Številka: 3
    Journal Article
    Recenzirano
    Odprti dostop

    The Schönberg-Chandrasekhar (SC) limit is a well-established result in the understanding of stellar evolution. It provides an estimate of the point at which an evolved isothermal core embedded in an ...
