  • Oxygen abundances of carbon-enhanced stellar population in the halo 
    Susmitha, A; Sivarani, T; Ojha, D. K; Ninan, Joe P; Bandyopadhyay, A; Surya, A; Athira, U (Springer, 2020-12)
    The large fraction of carbon-enhanced metal-poor (CEMP) stars at lower metallicities makes them an interesting class of objects to be probed further in greater detail. They show different abundance patterns of neutron-capture ...

    Garcia-Hernandez, D. A; Lambert, D. L; Kameswara Rao, N; Hinkle, K. H; Eriksson, K (Institute of Physics, 2010-05)
    We investigate the relationship between R Coronae Borealis (RCB) stars and hydrogen-deficient carbon (HdC) stars by measuring precise 16O/18O ratios for five cool RCB stars. The 16O/18O ratios are derived by spectrum ...
  • P Cygni type profiles 
    Peraiah, A; Srinivasa Rao, M (Indian Institute of Astrophysics, Bangalore, 1985-11)
    We have presented a series of P Cygni type profiles of special lines computed by employing different velocity laws of expansion in a spherically atmosphere. A comparison has been made with those of Beals classification. ...
  • p-capture reaction cycles in rotating massive stars and their impact on elemental abundances in globular cluster stars: A case study of O, Na and Al 
    Mahanta, Upakul; Goswami, A; Duorah, H. L; Duorah, K (IOP Publishing, 2017-08)
    Elemental abundance patterns of globular cluster stars can provide important clues for understanding cluster formation and early chemical evolution. The origin of the abundance patterns, however, still remains poorly ...
  • p-mode interaction with sunspots 
    Cally, P. S; Moradi, H; Rajaguru, S. P (John-Wiley and Sons, 2016)
    This chapter brings together two of the prominent features of our star the Sun: its well‐developed p‐mode spectrum of global oscillations excited by near‐surface convection, and its magnetic activity famously represented ...
  • The p-mode spectra of the roAp stars 
    Martinez, Peter (Astronomical Society of India, 1996)
    This paper discusses the general properties of the p-mode spectra of roAp stars and provides a table of these properties for the 28 currently known roAp stars.
  • P.R. Chidambara Ayyar elected as a fellow of the Royal Astronomical Society 
    Royal Astronomical Society (Royal Astronomical Society, 1925-01-09)
    This includes the announcement made in the journal Monthly Notices of Royal Astronomical Society regarding his election as a fellow of the Royal Astronomical Society, a letter proposing his name for the membership and ...
