  • Study of the ground state dissociation of diatomic molecular systems using state-specific multireference perturbation theory: a Brillouin-Wigner scheme 
    Mahapatra, U. S; Chattopadhyay, S; Chaudhuri, R. K (American Chemical Society, 2010-03)
    The size-extensive second-order state-specific (or single root) multireference (MR) perturbation theory (SS-MRPT) in the Brillouin-Wigner (BW) form using Moller-Plesset perturbative evaluations of orders up to 2 [termed ...
  • Advances in spectral classification 
    Giridhar, S (Astronomical Society of India, 2010-03)
    In this article we give an overview of the developments in the field of spectral classification, its continued importance in the fields of stellar and galactic evolution. The extension of MK system to cool stars as well ...
  • Chemical composition of A–F type post-AGB candidates 
    Giridhar, S; Molina, R; Arellano Ferro, A; Selvakumar, G (Wiley-Blackwell, 2010-07)
    An abundance analysis has been conducted for a sample of nine post-AGB candidate stars; eight of them have not been explored before.We find four very promising objects like HD 105262, HD 53300 and CpD−62o5428 among them. ...
  • Study of the continuous solar spectrum in the visible range 
    Ramanathan, A. S (C.N.R.S, 1954-01)
    Limb darkening observations made under excellent observing conditions are given for twenty-two wavelengths in the continuous spectrum of the sun in the region λ 3600-λ 6800; these observations were made at a time when the ...
  • Breaking up of a comet by Jupiter 
    Kameswara Rao, N; Mayya, Y. D; Reddy, B. E; Prabhu, T. P (Astronomical Society of India, 1993-09)
  • The climate of Madras and environs 
    Narayan, B. G (Indian Academy of Sciences, 1938)
  • Physics of the Solar Cycle: New Views 
    Hiremath, K. M (Balkan, Black Sea and Caspian Sea, 2010-11)
    Presently there are two schools of thought viz., turbulent dynamo and MHD oscillation mechanisms that explain the solar cycle and activity phenomena. Both the mechanisms are critically examined and fundamental difficulties ...
  • Changes of atmospheric electric potential gradient at Poona during disturbed weather 
    Sivaramakrishnan, M. V (The Manager Government of India Press, Simla, 1953-01)
    A detailed study of the changes of atmospheric potential gradient during disturbed weather at Poona for 5 years 1936-40 has been made. From the analysis it is seen that if during rainfall the potential gradient is negative ...
  • The sporadic E layer at Kodaikanal 
    Rangarajan, S (American Geophysical Union, 1954-06)
    An examination of the ionospheric records at Kodaikanal, which is located almost on the geomagnetic equator, reveals that the sporadic E layer here has some regular features not observed at other latitudes. It occurs in ...
  • Intensity variation in sunspots 
    Ananthakrishnan, R (Nature Publishing Group, 1951-08)
    The most conspicuous and readily observed feature of a normal sunspot is a dark central umbra surrounded by a less dark penumbral fringe which, under good seeing conditions, appears to be composed of converging filaments ...
  • Prominence activity and the sunspot cycle 
    Ananthakrishnan, R (Nature Publishing Group, 1952-07)
    The relationship that exists between the distribution and frequencies of prominences at the limb of the sun and the sunspot cycle has been discussed by several workers1. The most outstanding feature is the existence of two ...
  • A new early-morning ionospheric phenomenon 
    Bhargava, B. N (Nature Publishing Group, 1952-12)
    EARLY in January 1952, when ionospheric observations were started at Kodaikanal (10° 14' N., 77° 28' E.), an interesting phenomenon, which, to my knowledge, has not hitherto been reported, was observed in the vertical-incidence ...
  • Photometric study of the profiles of the Fraunhofer lines in the solar spectrum: Part 1. MG. b. Group 
    Paramasiva Rao, Y; Ananthasubrahmanyam, C. K (Calcutta University Press, 1942-06)
    The paper consists of the results of the photometric studies carried out by the authors during the last year. After a brief description of the improvements and refine ments perfected in the Direct-Reading Photo-electric ...
  • Distribution in latitude of the absorption markings in Hα spectroheliograms 
    Royds, T (Royal Astronomical Society, 1912-12)
  • The absorption markings in Hα spectroheliograms 
    Royds, T (Royal Astronomical Society, 1911-06)
  • Solar tides in the F2 region over Kodaikanal 
    Thiruvengadathan, A (Manager of Publications Civil Lines Delhi, 1955-08)
  • Very long sequences of geomagnetic activity and its annual variation 
    Bhargava, B. N; Naqvi, Ali. M (Nature Publishing Group, 1954-03)
    IT is well known that moderate geomagnetic storms tend to recur after 27 days. Such storms are not related to sunspots, are almost always of gradual commencement type and are well marked only during two or three years ...
  • Unusual solar activity 
    Salaruddin, MD; Narayan, B. G (Calcutta University Press, 1939-12)
    The paper describes briefly the outstanding features of a recent persistent solar activity observed in Kodaikanal. Attempts have been made to correlate the bright chromospheric eruptions with the terrestrial effects. It ...
  • The first spark spectrum of arsenic (As II) 
    Rao, A. S (Institute of Physics, 1932-05)
    The spectrum of arsenic has been examined under varying conditions of excitation, and lines belonging to the singly-ionized atom have been identified. Combinations between the deep terms of the singlet and triplet system ...
