Extended ring system of Uranus

Bhattacharyya, J. C; Bappu, M. K. V; Mohin, S; Mahra, H. S; Gupta, S. K (D. Reidel Publishing, 1979-12)

Two photoelectric records of the occultation event on 10 March, 1977, obtained by two 102-cm-aperture telescopes, spaced 1500 km apart, are critically analyzed and indications of a complex structure of distribution of ...
On emission lines of hydrogen, helium and ionized calcium seen on a coronal spectrogram of the march 7, 1970 eclipse

Bappu, M. K. V; Bhattacharyya, J. C; Sivaraman, K. R (D. Reidel Publishing, 1972-10)

Emission lines of the Balmer series, D3 and H and K are reported present on a coronal spectrogram obtained at the March 7, 1970 eclipse. Arguments are presented to show that these could not have originated from scattering ...
Photometry of the solar corona of March 7, 1970

Bappu, M. K. V; Bhattacharyya, J. C; Sivaraman, K. R (Indian Academy of Sciences, 1973)

Isophotes obtained by equidensitometry techniques from four exposures of the March 7, 1970 corona are used for derivation of intensity distributions along the equator, poles, streamers and dark ' gaps ' in the visible ...
Saturn-like ring system around Uranus

Bhattacharyya, J. C; Bappu, M. K. V (Nature Publishing Group, 1977-12)

A photoelectric record of the occultation of SAO 158687 by Uranus on March 10, 1977, is analyzed. The observed variation in the intensity of the star's light is shown to indicate the presence of four zones, which are ...
