Spectroscopic study of amethyst quartz in the ultraviolet and infrared regions

Bappu, M. K. V (Indian Association for the Cultivation of Science, 1953)

In this paper a study is made of the absorption of light in the ultravia!rt end infrared regions in amethyst quartz. In the ultraviolet the presence of the V-band is masked by the presence of iron impurity and it is ...
Spectroscopic study of amethyst quartz in the visible region

Bappu, M. K. V (Indian Association for the Cultivation of Science, 1952)

In this paper a detailed study is made of the absorption of light in the visible region by amethyst quartz. It is found that in the visible region, an absorption band, the so called F-band appears, which decreases in ...
On the visual light curve of RT. Eridani

Bappu, M. K. V (Indian Academy of Sciences, 1946-07)
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 ...
The effect of colour on the visual observation of long-period variable stars

Bappu, M. K. V (Indian Academy of Sciences, 1946-01)
The variation of emission line-intensities in CQ Cephei

Bappu, M. K. V (American Astronomical Society, 1952-04)
A spectroscopic study of Wolf-Rayet stars

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 ...
Evolution of research in different astronomies in India

Bhattacharyya, J. C (The Council of Scientific and Industrial Research, 1986-10)

The evolution of astronomical studies is reviewed with special reference to important achievements on Indian soil since the introduction of telescopic observations in the early seventeenth century. Important activities ...
Photographic observation of the Moon`s position

Bappu, M. K. V (NISCAIR, 1958)
A new satellite of Uranus

Bhattacharyya, J. C; Kuppuswamy, K (Nature Publishing Group, 1977-05)

During the observation of the occultation of the star SAO 158687 by Uranus on March 10, 1977, there occurred an unexpected event which suggests the existence of a hitherto unknown satellite of the planet. On the basis of ...
Observations of X-Per in optical domain

Sharma, D. P; Nagaraja, B. V; Bhattacharyya, J. C; Mohin, S; Raveendran, A. V (Kluwer Academic Publishers, 1983-09)

We have monitored the X-ray source X-Per (4U 0352+30) on 31 August, 1979 through aU filter for about 1.5 hr using 102-cm telescope of Kavalur observatory. During this period intensity of X-Per fluctuated for some time, on ...
