Photoelectric magnitudes of 26 stars in the field of King 21 have been obtained. The reddening is variable across the cluster. A distance of 1.91 kpc has been estimated for the cluster. It is concluded that the age of the ...

The Changes in the Ca II K line profile of the F0 supergiant Canopus have been studied from the high dispersion coude spectrograms obtained since 1975. The emission in the core of the line is variable in a timescale of few ...

Photoelectric observations of the Algol-type eclipsing binary R Canis Majoris during three consequtive observing seasons of 1979-82 gave a total of ten primary minima in each of the V and B passbands and nine in the U ...

An interesting solar flare occured on 1978 December 20 behind the north-west limb, in the McMath active region no. 15700, as inferred from the observed associated energtic mass ejections, strong x-rays, decimetric and ...

Father Richard who discovered the binary nature of alpha Centauri from Pondicherry is probably the first person to use a telescope on Indian soil. A brief sketch of his life and astronomical contributions from India are presented.

The recently published values of oscillator strengths for the Phillips bands were checked with those obtainable from the solar spectrum. The results of (1982) Erman et al. based on the assumption of a varying electronic ...

Planetesimals are intermediate stages, in the kilometer size range between interstellar matter and large bodies such as planets and stars. Planetesimals can still be studied in the form of asteroids although they have been ...

Spectrograms of the inner solar corona were obtained during the 1980 total solar eclipse. Two Ebert-Fastie type spectrographs with circular slits were used to obtain spectra on the east and the west at 1.06 R. These ...

The observations of the 1980 March 28, 2B flare in optical, radio microwave and metric and x-ray wavelengths are presented. In the dynamic radio spectrum, unusual and rare U-shaped type II radio bursts associated with this ...
