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 ...
  • Effect of asymmetry in peak profile on f-mode frequencies 
    Antia, H. M; Basu, S (Astronomical Society of India, 2000)
  • The eleventh and twelfth data releases of the sloan digital sky survey: final data from SDSS-III 
    Alam, S; Albareti, F. D; Prieto, C. A; Anders, F; Anderson, S. F; Anderton, T; Andrews, B. H; Armengaud, E; Aubourg, E; Bailey, S; Basu, S; Bautista, J. E; Beaton, R. L; Beers, T. C; Bender, C. F; Berlind, A. A; Beutler, F; Bhardwaj, V; Bird, J. C; Bizyaev, D; Blake, C. H; Blanton, M. R; Blomqvist, M; Bochanski, J. J; Bolton, A. S; Bovy, J; Bradley, A. S; Brandt, W. N; Brauer, D. E; Brinkmann, J; Brown, P. J; Brownstein, J. R; Burden, A; Burtin, E; Busca, N. G; Cai, Z; Capozzi, D; Rosell, A. C; Carr, M. A; Carrera, R; Chambers, K. C; Chaplin, W. J; Chen, Y-C; Chiappini, C; Chojnowski, S. D; Chuang, C-H; Clerc, N; Comparat, J; Covey, K; Croft, R. A. C; Cuesta, A. J; Cunha, K; da Costa, L. N; Da Rio, N; Davenport, J. R. A; Dawson, K. S; De Lee, N; Delubac, T; Deshpande, R; Dhital, S; Dutra-Ferreira, L; Dwelly, T; Ealet, A; Ebelke, G. L; Edmondson, E. M; Eisenstein, D. J; and 237 coauthors; Sivarani, T (IOP Publishing, 2015-07-20)
    The third generation of the Sloan Digital Sky Survey (SDSS-III) took data from 2008 to 2014 using the original SDSS wide-field imager, the original and an upgraded multi-object fiber-fed optical spectrograph, a new ...
  • Excitation of Solar p-mode Oscillations by Flares 
    Ambastha, A; Basu, S; Antia, H. M (Astronomical Society of India, 2003)
    Solar flares release large amounts of energy at different layers of the solar atmosphere. It is, therefore, expected that major flares would be able to excite waves, thereby affecting the p-mode oscillation characteristics. ...
  • Helioseismic detections of overshoot below the solar convection zone 
    Basu, S; Antia, H. M; Narasimha, D (Astronomical Society of India, 1993)
    It is generally accepted that there is no adequate theory to describe astrophysical convection. In particular, there is no agreement among different theories about the extent of overshoot from stellar convection zones. The ...
  • Helium abundance in the solar envelope 
    Basu, S (Astronomical Society of India, 2000)
  • The infall time-scale in the solar neighborhood 
    Basu, S (Astronomical Society of India, 1993)
    The Galactic disk is supposed to have been formed from gas condensing out from the halo. The rate at which this infall of gas occurs, the amount of infall, and the time scales over which gas falls on to the disc have ...
  • Ionospheric electron content and equivalent slab thickness in the equatorial region 
    Das Gupta, A; Basu, S; Bhar, J. N; Bhattacharyya, J. C (American Geophysical Union, 1975-02)
    The ionospheric total electron content and equivalent slab thickness in the equatorial region around 75° E have been studied. It is found that the slab thickness exhibits a strong latitudinal dependence with a maximum at ...
  • Ring Diagram Analysis of the Characteristics of Solar Oscillation Modes in Active Regions 
    Rajaguru, S. P; Basu, S; Antia, H. M (The American Astronomical Society, 2001-12)
    The presence of intense magnetic fields in and around sunspots is expected to modify solar structure and oscillation frequencies. Applying the ring diagram technique to data from the Michelson Doppler Imager on board the ...
  • The seismic sun 
    Basu, S (Astronomical Society of India, 2000)
    The "Seismic Sun" is a model of the Sun constructed using helioseismological deductions about the Sun. The seismic Sun is very similar to a standard solar model which incorporates gravitational settling of helium and heavy ...
  • 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 ...
  • The spatial and temporal evolution of gas and heavy elements in the galaxy 
    Basu, S (Astronomical Society of India, 1993)
