  • Coronal Electron Density and the Gradient of Coronal Rotation with Altitude 
    Vats, H. O (Astronomical Society of India, 2003)
    The calculations of the gradient of coronal rotation period with altitude were performed using electron density model and the radio measurements of solar coronal rotation. The magnitude of the gradient reduces if the ...

    Deshpande, M. R; Vats, H. O; Sethia, G; Murthy, B. S (Nature Publishing Group, 1977-08)
  • Effect of electrojet on the total electron content of the ionosphere over the Indian subcontinent 
    Deshpande, M. R; Rastogi, R. G; Vats, H. O; Sethia, G; Klobuchar, J. A; Jain, A. R; Subbarao, B. S; Patwari, V. M; Janve, A. V; Rai, R. K; Singh, M; Gurm, H. S; Murthy, B. S (Nature Publishing Group, 1977-06)
    The radio beacon method of measuring TEC along a chain of optimally spaced stations near the equatorial anomaly has been used to monitor continuously the latitudinal extent of the anomaly. Comparisons with the magnitude ...
  • Equatorial irregularity belt and its movement during a magnetic storm 
    Vats, H. O; Chandra, H; Deshpande, M. R; Rastogi, R. G; Murthy, B. S; Janve, A. V; Rai, R. K; Singh, M; Gurm, H. S; Jain, A. R (Nature Publishing Group, 1978-03)
    GEOSTATIONARY satellites are able to monitor amplitude, phase, plane of polarisation (Faraday rotation) and group retardation of radio waves passing through the ionosphere with improved temporal resolution, although some ...
  • Instrumentation of "Solar X-Ray Spectrometer" Low Energy Detector (SLD) - Proposed payload onboard Indian satellite 
    Vadher, N. M; Shah, A. B; Rajmal, J; Vats, H. O; Deshpande, M. R; Seetha, S; Murthy; Sharma, R. K; Umapathy (Astronomical Society of India, 2000)
    It is proposed to fly a high spectral and temporal resolution - "Solar X-Ray Spectrometer (SOXS)" onboard Indian satellite. The SOXS will provide the disk integrated flux in the energy range 2 keV-10 MeV. It is composed ...
  • Ionosphere scintillations associated with features of equatorial ionosphere 
    Chandra, H; Vats, H. O; Sethia, G; Deshpande, M. R; Rastogi, R. G; Sastri, J. H; Murthy, B. S (European Geophysical Society, 1979-09)
    Amplitude scintillations of radio beacons aboard the ATS-6 satellite on 40 MHz, 140 MHz and 360 MHz recorded during the ATS-6 phase II at an equatorial station Ootacamund (dip 4 deg N) and the ionograms at a nearby station ...
  • Ionospheric Effects During February 1980 Solar Eclipse 
    Chandra, H; Deshpande, M. R; Vyas, G. D; Sethia, G; Vats, H. O; Iyer, K. N (Astronomical Society of India, 1980-12)
    Highlights of the ionospheric effects of the total solar eclipse of February 16, 1980 detected by ground-based experiments in India are summarised. Decrease in electron density at various height in ionosphere upto the F2 ...
  • Parameters of interplanetary medium 
    Oza, R. M; Vats, H. O; Iyer, K. N; Deshpande, M. R (Astronomical Society of India, 1998)
  • Radio emission as a diagnostic for solar coronal rotation 
    Vats, H. O; Deshpande, M. R; Mehta, M; Shah, C. R; Shah, K. J (Astronomical Society of India, 1999)
    The time series of solar radio emission at 2.8 GHz is analysed using correlation methods. The analysis showed that this type of time series can be used to infer the rotation period of the source (in this case solar corona). ...
  • Science from "Solar X-ray Spectrometer (SOXS)" - Proposed payload onboard Indian satellite 
    Jain, R; Rao, A. R; Deshpande, M. R; Dwivedi, B. N; Manoharan, P. K; Seetha, S; Vahia, M. N; Vats, H. O; Venkatakrishnan, P (Astronomical Society of India, 2000)
    It is proposed to fly a high spectral and temporal resolution "Solar X-ray Spectrometer (SOXS)" onboard Indian satellite to understand the mechanisms of energy release and particle acceleration in solar flares. The SOXS ...
