  • Vagiswari, A; Louis, C (Elsevier, 1995)
    This paper analyses the change in the referencing pattern among the astronomers. There has been an increase in the number of conference proceedings (CP) during the last 10 years. In astronomy alone there were around 131 ...
  • Ankit Kumar; Kataria, Sandeep Kumar (Oxford University Press on behalf of Royal Astronomical Society, 2022-08)
    Cosmological simulations predict more classical bulges than their observational counterparts in the local Universe. Here, we quantify evolution of the bulges since z = 0.1 using photometric parameters of nearly 39 000 ...

    The third observing run by LVC has brought the discovery of many compact binary coalescences. Following the detection of the fi rst binary neutron star merger in this run ( LIGO / Virgo S190425z ) , we performed ...

    S190426c/GW190426 152155 was the first probable neutron star–black hole merger candidate detected by the LIGO-Virgo Collaboration. We undertook a tiled search for optical counterparts of this event using the 0.7-m ...
  • Sharma, Kritti; Kumar, Harsh; Bolin, Bryce; Bhalerao, Varun; Anupama, G. C; Barway, Sudhanshu (Europlanet Science Congress, 2021-09)
    The discovery, characterisation, and monitoring of Near-Earth Objects (NEOs) are critical for understanding and potentially mitigating the long-term threats to our civilisation from Potential Hazardous Asteroids (PHAs). ...
  • Kjurkchieva, D. P; Dimitrov, D. P; Ibryamov, S. I.; Srinivasa Rao, M (Astronomical Society of India, 2013-06)
    Our BVI photometric observations reveal that GSC 2701-2527 is a high amplitude ᵟ Scuti star with quite low temperature. The frequency analysis exhibits that it is multiperiodic pulsator. The obtained period ratio f1/ ...
  • Rajesh Nayak, K; Vishveshwara, C. V (Springer, 1997-03)
    The phenomenon of gyroscopic precession in the Ernst spacetime is studied within the framework of the Frenet-Serret formalism. General formulae are obtained for circular orbits. At the same time general relativistic analogues ...
  • Rajesh Nayak, K; Vishveshwara, C. V (Springer, 1998-04)
    We study the phenomenon of gyroscopic precession and the analogues of inertial forces within the framework of general relativity. Covariant connections between the two are established for circular orbits in stationary ...
  • Rajesh Nayak, K; Vishveshwara, C. V (IOP Publishng, 1996-07)
    The phenomenon of gyroscopic precession in the Kerr-Newman spacetime is studied using the Frenet-Serret formalism. General formulae are obtained for circular quasi-Killing trajectories. The motion on the equatorial plane ...
  • Javaraiah, J (Springer, 2012-12)
    We have analyzed the combined Greenwich and Solar Optical Observing Network (SOON) sunspot group data during the period of 1874 – 2011 and determined variations in the annual numbers (counts) of the small (maximum area ...
  • Aditya, K; Banerjee, Arunima; Kamphuis, Peter; Mosenkov, Aleksandr; Makarov, Dmitry; Borisov, Sviatoslav (Oxford University Press on behalf of Royal Astronomical Society, 2023-11)
    Superthin galaxies are bulgeless low-surface brightness galaxies with unusually high major-to-minor axes ratio of the stellar disc, i.e. 10 < a/b < 20. We present Giant Metrewave Radio Telescope (GMRT) H I 21cm radio-synthesis ...

    We report the radio detection of a shell-like H i structure in proximity to, and probably associated with, the nova V458 Vul. High spectral resolution observation with the Giant Metrewave Radio Telescope has made it possible ...
  • Valluri, M; Anupama, G. C (American Astronomical Society, 1996-10)
    We report results of a search for optical emission line gas in the Hickson compact group 62. From narrow band (Hα) imaging observations we estimate 10^4^ M_sun_ of ionized hydrogen gas within the central regions of three ...
