Polarization measures of Comet Arend-Roland (1956h) and Comet Mrkos (1957d).

Bappu, M. K. Vainu; Sinvhal, S. D. (Monthly Notices of RAS, 160)

Measurements of polarization of Comet Arend-Roland and of Comet Mrkos made photoelectrically, using interference filters and conventional B, V filters are given. The interference filters were chosen to isolate the Na ...
Physical conditions in wolf-rayet atmospheres

Bappu, M. K. Vainu (1957-10-31)

A critical discussion of present-day knowledge regarding the Wolf-Rayet atmosphere is presented. It is shown that the large widths usually ascribed to the emission lines are formed by heavy blending, and that the individual ...
Polarization of comet arend-roland

Bappu, M. K.; Sinvhal, S. D. (Nature, 1957-12-21)
A physical analysis of Wolf-Rayet spectra

Bappu, M. K. Vainu (1958)
Interference filter photometry of weak emission lines in cq cephei

Bappu, M. K. Vainu; Sinvhal, S. D. (Vincent Baxter Press , Oxford, 1959)
The light variation of 6 Cassiopeiae

Bappu, M. K. Vainu (1959-06)
Study of variations of the forbidden oxygen lines in the nightglow

Pande, M. C.; Varma, S. D. (Northern Ireland, 1960)

The variations of the forbidden oxygen lines in the nightglow are investigated photoelectrically using a fixed orientation photometer set in a star free region near the north celestial pole. For the red lines our observations ...
Photoelectric observations of the eclipsing binary 32 Cygni

Chandra, S.; Pande, M. C. (1960-08)
A preliminary note on the light variations in tau Cygni

pande, M. C. (1960-12)
A note on the period of EH Librae

Sanwal, N. B.**********; Pande, M. C. (1961-10)
Some observations on the light variability of RY Bootis

Sanwal, N. B.; Pande, N. B. (1961-10)
Photoelectric measures of Hydrogen-line absorption in early-type stars

Bappu, M. K. Vainu; Chandra, S.; Sanwal, N. B.; Sinvhal, S. D. (1962)

Photoelectric determinations of H absorption line intensity have been made of stars in selected clusters and associations as well as in the general galactic field. Interference filters having a width at half intensity of ...
A note on the period variation of CY Aquarii

Sanwal, N. B. (1962)
Observations of the occultation of BD -5 5863 by Pallas

Sinvhal, S. D.; Sanwal, N. B.; Pande, M. C. (1962)
On the variability of IM Monocerotis

Sanyal, A.; Sinvhal, S. D. (1964)
Dependence of molecular dissociation equilibrium on magnetic field strength in sunspots

Gaur, V. P.; Pande, M. C.; Tripathi, B. M.; Joshi, G. C. (1971)

It is shown that the total number of CO, CN, C₂, UH, NH and CH molecules varies significantly with magnetic field strength in sunspots. The equivalent widths of two first overtone lines of CO belonging to 0-2 vibration-rotation ...
Molecules in eta aquilae

Pande, M. C.; Joshi, G. C.; Tripathi, B. M.; Gaur, V. P. (1971)

The total numbers Iφ(AB) of a given molecule AB in a column extending between τ=0 to τ=3.00 have been calculated for various phases ɸ of light variations in η Aql for the molecules CO, CN, C ₂ , OH, NH and CH. It is found ...
A note on the effect of scattered light on the facula-to-photosphere contrast

Pande, M. C.; Tripathi, B. M.; Gaur, V. P. (1971)

The measured facula-to-photosphere contrast in the continuum radiation corrected for the scattered light should yield a hotter average facula model than the models derived without such a correction.
The dissociation equilibrium of some diatomic molecules in Delta Cephei

Pande, M. C.; Tripathi, B. M.; Murthy, C. S.; Gaur, V. P. (1971)

The dissociation equilibrium of CO, CN, C₂, CH, NH and OH is considered for the maximum and minimum phases of the light curve of δ Cep. Concentration-optical depth curves show that with both the phases the abundances ...
Spectrophotometry of comet Bennett

Babu, G. S. D.; Saxena, P. P. (1972)

Phtotoelectric spectrum scans of the head of comet Bennett (1969i) covering the range 352÷612 mμ are presented and the emission features of CN, CH, C₂ and Na have been identified. The scattered light becomes redder as the ...
