  • Natarajan, V; Rajamohan, R (Kodaikanal Observatory, 1971)
    A velocity curve of the spectroscopic binary 'Delta Orionis' has been obtained from the spectrograms taken at kodaikanal during the years 1968-70. The orbital elements derived are in good agreement with earlier values ...

  • Birdie, C; Sreeharsha, B. G; Pallavi, T. G; Kannur, Mahantesh B (INFLIBNET Centre, 2003)
    Electronic journals unfold their most valuable features when they are inter-linked with other documents, archives and databases. These electronic journals need an archiving system that is based on a global concept. ...
  • Distefano, E; Messina, S; Cutispoto, G; Parihar, P. S; Comparato, M; Busá, I; Lanza, A. F; Lanzafame, A. C; Pagano, I; Strassmeier, K. G (EDP Sciences, 2007)
    The huge amount of CCD photometric data collected by robotic telescopes (as for instance the ICE-T telescope to be installed at Dome-C) requires a fully automated approach to the reduction and analysis procedures. To this ...
  • García-Hernández, D. A; Kameswara Rao, N; Lambert, D. L (IOP Publishing, 2011-03-10)
    The hydrogen-poor, helium-rich, and carbon-rich character of the gas around R Coronae Borealis (RCB) stars has been suggested to be a site for formation of C60 molecules. This suggestion is not supported by observations ...
  • Bhowmick, A; Pandey, G; Joshi, V; Ashok, N. M (IOP Publishing, 2018-02)
    Are DY Persei Stars Cooler Cousins of R Coronae Borealis Stars? Anirban Bhowmick 1 , Gajendra Pandey 1 , Vishal Joshi 2 , and N. M. Ashok 2 1 Indian Institute of Astrophysics, Koramangala, Bengaluru 560 034, ...
  • Bhattacharyya, Archita; Alam, Ujjaini; Pandey, Kanhaiya L; Das, Subinoy; Pal, Supratik (IOP Publishing, 2019-05-10)
    Yes, for a wide range of cosmological models (ΛCDM, non-interacting wz CDM, wz WDM, or a class of interacting DMDE). Recently there have been attempts to solve the tension between direct measurements of H0 and s8 0m W from ...
  • Viswanath, G; Stalin, C. S; Rakshit, S; Kurian, K. S; Ujjwal, K.; Gudennavar, S. B; Kartha, S. S (IOP Publishing, 2020-03)
    Are Narrow-line Seyfert 1 Galaxies Powered by Low-mass Black Holes? Gayathri Viswanath 1 , C. S. Stalin 2 , Suvendu Rakshit 3 , Kshama S. Kurian 2 , K. Ujjwal 1 , Shivappa B. Gudennavar 1 , and Sreeja S. ...
  • Korchagin, V; Kembhavi, A. K; Mayya, Y. D; Prabhu, T. P (The American Astronomical Society, 1995-06)
    We investigate self-regulated propagation of stars formation, which is one of the possible scenarios of stars formation in molecular clouds fragmented into cold dense structures with masses lying near the Jeans limit. ...
  • Sivaraman, K. R; Antia, H. M; Chitre, S. M (Springer, 2010)
    Polar faculae (PF) are bright, small-scale structures measuring a few seconds of arc, populating the polar zones at latitudes >50°. They possess magnetic fields ranging from 150 to 1,700 Gauss and largely constitute the ...
  • Kapoor, R. C; Shukre, C. S (Astronomical Society of India, 2001)
    Pulsar radio pulses are made up of the so called core and conal components. A remarkably precise relation for core component widths, found observationally, in effect specifies the size of the polar cap on pulsars. Inclusion ...
  • Kapoor, R. C; Shukre, C. S (EDP Sciences, 2001-08)
    A remarkably precise observational relation for pulse core component widths of radio pulsars is used to derive stringent limits on pulsar radii, strongly indicating that pulsars are strange stars rather than neutron stars. ...
  • Su, Li-Hsin; Jiang, Ing-Guey; Sariya, Devesh P; Lee, Chiao-Yu; Yeh, Li-Chin; Mannaday, Vineet Kumar; Thaku, Parijat; Chand, Swadesh; Shlyapnikov, A. A; Moskvin, V. V; Ignatov, Vladimir; Mkrtichian, David; Griv, Evgeny; Sahu, D. K (IOP Publishing, 2021-03-01)
    Motivated by the unsettled conclusion on whether there are any transit timing variations (TTVs) for the exoplanet Qatar-1b, 10 new transit light curves are presented and a TTV analysis with a baseline of 1400 epochs is ...
  • Sivaram, C (Deccan Herald, 2008-12-09)
  • Rautela, B. S; Joshi, G. C; Pandey, J. C (Astronomical Society of India, 2004-09)
    An Imaging Polarimeter has been fabricated for use with liquid- N2 cooled CCD camera and is designed to suit 104-cm Sampurnanand telescope with an f/13 focus at Aryabhatta Research Institute of Observational Sciences ...
  • Bhattacharjee, Samaresh; Naja, Manish; Jaiswal, Aditya; Rawat, Kishan Singh; Sagar, Ram; Ananthakrishnan, S (World Scientific Publishing Company, 2022-12)
    Recently, a 206.5MHz Stratosphere Troposphere (ST) Radar system was successfully installed and made operationalized at Aryabhatta Research Institute of Observational Sciences (ARIES) (29.4N, 79.2E, 1793m amsl), Nainital, ...
  • Sagar, R; Dumka, U. C; Naja, M; Singh, N; Phanikumar, D. V (Indian Academy of Sciences, 2015-08-25)
    ARIES, acronym for Aryabhatta Research Institute of Observational Sciences, located in the Central Gangetic Himalayan (CGH) region is emerging as one of the unique sites for climate change studies. The long-term, in situ, ...
