Activity dependence of solar supergranular fractal dimension

Paniveni, U; Krishan, V; Singh, J; Srikanth, R (Blackwell Publishing, 2010-02)

We study the complexity of supergranular cells using the intensity patterns obtained at the Kodaikanal Solar Observatory during the solar maximum. Our data consist of visually identified supergranular cells, from which a ...
A comparison of synthetic and observed spectra for G-K dwarfs using artificial neural networks

Gulati, R. K; Gupta, R; Kameswara Rao, N (European Southern Observatory, 1997-06)

A library of synthetic spectra, based on Kurucz model atmospheres, has been used to compare the spectroscopic observations in the wavelength range 4850-5384 Å by using statistical and supervised artificial neural network ...
Seismic and spectroscopic characterization of the solar-like pulsating CoRoT target HD 49385

Deheuvels, S; Bruntt, H; Michel, E; Barban, C; Verner, G; Régulo, C; Mosser, B; Mathur, S; Gaulme, P; Garcia, R. A; Boumier, P; Appourchaux, T; Samadi, R; Catala, C; Baudin, F; Baglin, A; Auvergne, M; Roxburgh, I. W; Pérez Hernández, F (EDP Science, 2010-06-11)

Context. The star HD 49385 is the first G-type solar-like pulsator observed in the seismology field of the space telescope CoRoT. The satellite collected 137 days of high-precision photometric data on this star, confirming ...
