  • Application of local-area helioseismic methods as predictors of space weather 
    Jensen, J. M; Lundstedt, H; Thompson, M. J; Pijpers, F. P; Rajaguru, S. P (European Space Agency, 2004-10)
    Space weather is growing concern to our increasingly technological society. Here we discuss neural-network approaches to forecasting space weather, in which we plan to incorporate now-cast information about solar sub-surface ...
  • The asteroseismic potential of Kepler: first results for solar-type stars 
    Chaplin, W. J; Appourchaux, T; Elsworth, Y; Garcia, R. A; Houdek, G; Karoff, C; Metcalfe, T. S; Molenda-Zakowicz, J; Monteiro, M. J. P. F. G; Thompson, M. J; Brown, T. M; Kiss, L. L; Kitiashvili, I. N; Kolenberg, K; Korhonen, H; Kosovichev, A. G; Kupka, F; Lebreton, Y; Leroy, B; Ludwig, H. G; Mathis, S; Michel, E; Miglio, A; Montalban, J; Moya, A; Noels, A; Noyes, R.

S; D'Antona, F; Deheuvels, S; Derekas, A; Garcia Hernandez, A; Giampapa, M. S; Goupil, M. J; Gruberbauer, M; Guzik, J. A; Hale, S. J; Ireland, M. J (IOP Publishing, 2010-04)
    We present preliminary asteroseismic results from Kepler on three G-type stars. The observations, made at one-minute cadence during the first 33.5d of science operations, reveal high signal-to-noise solar-like oscillation ...
  • Comparison of GONG and MDI sound-speed anomalies beneath two active regions 
    Hughes, S. J; Rajaguru, S. P; Thompson, M. J (European Space Agency, 2004-10)
    Travel times of acoustic waves are calculated from Dopplergrams of solar oscillations obtained using the Global Oscillation Network Group (GONG) ground-based network and the Michelson Doppler Imager (MDI) instrument on ...
  • The effect of strong magnetic fields on acoustic power in their surroundings at the surface of the sun 
    Nicholas, C. J; Thompson, M. J; Rajaguru, S. P (European Space Agency, 2004-10)
  • Modeling the Subsurface Structure of Sunspots 
    Moradi, H; Baldner, C; Birch, A. C; Braun, D. C; Cameron, R. H; Duvall, T. L; Gizon, L; Haber, D; Hanasoge, S. M; Hindman, B. W; Jackiewicz, J; Khomenko, E; Komm, R; Rajaguru, S. P; Rempel, M; Roth, M; Schlichenmaier, R; Schunker, H; Spruit, H. C; Strassmeier, K. G; Thompson, M. J; Zharkov, S (Springer, 2010-11)
    While sunspots are easily observed at the solar surface, determining their subsurface structure is not trivial. There are two main hypotheses for the subsurface structure of sunspots: the monolithic model and the cluster ...
  • Results from the LOWL instrument 
    Schou, J; Tomczyk, S; Thompson, M. J (Astronomical Society of India, 1996)
    We present various results from one year of observations with the LOWL instrument, which is designed to observe oscillations with degrees l from 0 to about 100. Among the results shown is an inversion for the solar rotaion ...
  • Solar structure as revealed by 1 year LOWL data 
    Basu, S; Christensen-Dalsgaard, J; Schou, J; Thompson, M. J; Tomczyk, S (Astronomical Society of India, 1996)
    We have used solar frequencies obtained form 1 year of observations with LOWL instrument to investigate the radial stratification of the Sun. Models which include the diffusion of helium and heavy elements below the solar ...
