    Stello, D; Basu, S; Bruntt, H; Mosser, B; Stevens, I. R; Brown, T. M; Christensen-Dalsgaard, J; Gilliland, R. L; Kjeldsen, H; Arentoft, T; Ballot, J; Barban, C; Bedding, T. R; Chaplin, W. J; Elsworth, Y. P; Garcia, R. A; Goupil, M. J; Hekker, S; Huber, D; Mathur, S; Meibom, S; Samadi, R; Sangaralingam, V; Baldner, C. S; Belkacem, K; Biazzo, K; Brogaard, K; Suarez, J. C; D'Antona, F; Demarque, P; Esch, L; Gai, N; Grundah, F; Lebreton, Y; Jiang, B; Jevtic, N; Karoff, C; Miglio, A; Molenda-Zakowicz, J; Montalban, J; Noels, A; Roca Cortes, T; Roxburgh, I. W; Serenelli, A. M; Silva, V; Christiaan Sterken, A; Stine, P; Szabo, R; Weiss, A; Borucki, W. J; Koch, D; Jenkins, J. M (Institute of Physics, 2010-04)
    Asteroseismology of stars in clusters has been a long-sought goal because the assumption of a common age, distance and initial chemical composition allows strong tests of the theory of stellar evolution. We report results ...
  • Determining global parameters of the oscillations of solar-like stars 
    Mathur, S; Garcia, R. A; Regulo, C; Creevey, P. L; Ballot, J; Salabert, D; Arentoft, T; Quirion, P. O; Chaplin, W. J; Kjeldsen, H (EDP Sciences, 2010-02)
    Helioseismology has enabled us to better understand the solar interior, while also allowing us to better constrain solar models. But now is a tremendous epoch for asteroseismology as space missions dedicated to studying ...
  • Estimating the parameters of globular cluster M 30 (NGC 7099) from time-series photometry 
    Kains, N; Bramich, D. M; Ferro, A. A; Jaimes, R. F; Jorgensen, U. G; Giridhar, S; Penny, M. T; Alsubai, K. A; Andersen, J. M; Bozza, V; Browne, P; Burgdorf, M; Novati, S. C; Damerdji, Y; Diehl, C; Dodds, P; Dominik, M; Elyiv, A; Fang, X.-S; Giannini, E; Gu, S.-H; Hardis, S; Harpsoe, K; Hinse, T.

N; Lundkvist, M; Mancini, L; Martin, R; Mathiasen, M; Rabus, M; Rahvar, S; Ricci, D; Sahu, D. K; Scarpetta, G; Skottfelt, J; Snodgrass, C; Southworth, J; Surdej, J; Tregloan-Reed, J; Vilela, C; Wertz, O; Williams, A (EDP Sciences, 2013-07)
    Aims. We present the analysis of 26 nights of V and I time-series observations from 2011 and 2012 of the globular cluster M 30 (NGC 7099). We used our data to search for variable stars in this cluster and refine the periods ...
  • A search for solar-like oscillations in the stars of M67 with CCD ensemble photometry on a network of 4 M telescopes 
    Gilliand, R. L; Brown, T. M; Kjeldsen, H; McCarthy, J. K; Peri, M. L; Belmonte, J. A; Vidal, I; Cram, L. E; Palmer, J; Frandsen, S; Parthasarathy, M; Petro, L; Schneider, H; Stetson, P. B; Weiss, W. W (American Astronomical Society, 1993-12)
    Results are presented from a large observational project directed toward the detection of solar-like oscillations in an ensemble of open cluster stars. Seven groups collaborated in 1992 January to observe twelve stars in ...
  • Solar-like oscillations in low-luminosity red giants: first results from Kepler 
    Bedding, T. R; Huber, D; Stello, D; Elsworth, Y. P; Hekker, S; Kallinger, T; Mathur, S; Mosser, B; Preston, H. L; Ballot, J; Barban, C; Broomhall, A. M; Buzasi, D. L; Chaplin, W. J; Garcia, R. A; Gruberbauer, M; Hale, S. J; De Ridder, J; Frandsen, S; Borucki, W. J; Brown, T; Christensen-Dalsgaard, J; Gilliland, R. L; Jenkins, J. M; Kjeldsen, H; Koch, D; Belkacem, K; Bildsten, L; Bruntt, H; Campante, T. L; Deheuvels, S; Derekas, A; Dupret, M. A; Goupil, M. J; Hatzes, A; Houdek, G; Ireland, M. J; Jiang, C; Karoff, C; Kiss, L. L; Lebreton, Y; Miglio, A; Montalban, J; Noels, A; Roxburgh, I. W; Sangaralingam, V; Stevens, I. R; Suran, M. D; Tarrant, N. J; Weiss, A (IOP Publishing, 2010-04)
    We have measured solar-like oscillations in red giants using time-series photometry from the first 34 days of science operations of the Kepler Mission. The light curves, obtained with 30-minute sampling, reveal clear ...
