  • Survey of Li-rich giants among Kepler and LAMOST fields: determination of Li-rich giants' evolutionary phase 
    Raghubar Singh; Reddy, B. E; Bharat Kumar, Y; Antia, H. M (IOP Publishing, 2019-06-10)
    In this Letter, we report the discovery of 24 new super Li-rich (A(Li) ≥ 3.2) giants of He-core burning phase at the red clump region. Results are based on a systematic search of a large sample of about 12,500 giants common ...
  • Time-distance helioseismology of deep meridional circulation 
    Rajaguru, S. P; Antia, H. M (Springer, 2020)
    A key component of solar interior dynamics is the meridional circulation (MC), whose poleward component in the surface layers has been well observed. Time-distance helioseismic studies of the deep structure of MC, however, ...
  • Waves in the sunspot penumbra 
    Antia, H. M; Chitre, S. M; Gokhale, M. H (Springer, 1978-11)
    Sunspot theory is discussed with reference to the role played by the spot magnetic field in influencing the mode of energy transport. Consideration is given to the stability of a plane parallel polytropic fluid layer with ...
  • Zonal velocity bands and the solar activity cycle 
    Sivaraman, K. R; Antia, H. M; Chitre, S. M; Makarova, V. V (Springer Netherlands, 2008-09)
    We compare the zonal-flow pattern in subsurface layers of the Sun with the distribution of surface magnetic features such as sunspots and polar faculae. We demonstrate that, in the activity belt, the butterfly pattern of ...
