  • Are Nuclear Hot Spots in Galaxies Sites of Sequential Star Formation? 
    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. ...
  • Are polar faculae generated by a local dynamo? 
    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 ...
  • Are pulsars strange? 
    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 ...
  • Are radio pulsars strange stars? 
    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. ...
  • Are there transit timing variations for the exoplanet qatar-1b? 
    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 ...

    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, ...
  • ARIES, Nainital: a strategically important location for climate change studies in the Central Gangetic Himalayan region 
    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, ...

    We report on H α + [N II] imaging of the Arp 202 interacting pair and its tidal dwarf galaxy (TDG) candidate as well as a GMOS long slit spectrum from the TDG candidate, observed with the Gemini North telescope. Our H α + ...
  • Artificial Neural Network-based Image-cleaning Method for Atmospheric Cerenkov Imaging Telescopes 
    Dhar, V. K; Tickoo, A. K; Kaul, M. K; Kaul, C. L; Rannot, R. C; Yadav, K. K; Dubey, B. P; Koul, R (Astronomical Society of India, 2003)
    A novel image-cleaning method, based on the utilization of Artificial Neural Network (ANN) is shown here to `correctly' select more pixels in a Cerenkov image than in the conventional approach.
