  • Recent advances in RV Tauri stars 
    Giridhar, S (Indian Academy of Sciences, 2020-12)
    The availability of multi-wavelength observations and parallaxes from the space missions and very comprehensive models of AGB evolution that include the accretion of matter from the circumbinary disc have strongly impacted ...
  • Recent Developments in Polarized Line Formation in Magnetic Fields 
    Nagendra, K. N; Sampoorna, M; Anusha, L. S (Springer, 2010)
    The nature of solar surface magnetism has been an open problem in solar physics. In this paper we address three frontline problems of spectropolarimetry of the Sun. We first review the theoretical formulation and numerical ...

  • The recent signs of total column ozone recovery over mid-latitudes: the effects of the montreal protocol mandate 
    Shantikumar, S. N; Vemareddy, P; Song, H. -J (Elsevier B.V, 2018-10)
    After successful implementation of the Montreal Protocol, total ozone column (TOC) has considerably increased since the mid 1990s. However, the recovery is weak and statistically non-significant particularly at low-latitudes ...
  • Recent star formation history of the Large and Small Magellanic Clouds 
    Indu, G; Subramaniam, A (Astronomical Society of India, 2012)
    Recent interactions between the Large and the Small Magellanic Clouds (LMC and SMC) and the Milky Way can be understood by studying their recent star formation history. We traced the age of the last star-formation event ...
  • The recent star-formation history of the Large and Small Magellanic Clouds 
    Indu, G; Subramaniam, A (EDP Sciences, 2011-11)
    Aims. Recent interactions between the Large and the Small Magellanic Clouds (LMC and SMC) and the Milky Way can be understood by studying their recent star formation history. This study aims to detect any directional or ...
  • Recent unusual solar activity 
    Salaruddin, MD; Narayan, B. G (The Observatory, 1940-01)
  • Reception of Radio Waves from Pulsars 
    Gangadhara, R. T (International Astronomical Union, 2004)
    The beamed emission by relativistic sources moving along the magnetic dipolar field lines occurs in the direction of tangents to the field lines. To receive such a beamed radiation, the line of sight must align with the ...
  • Reconnection-generated Plasma Flows in the Quasi-separatrix Layer in Localized Solar Corona 
    Mondal, Sripan; Srivastava, Abhishek K; Mishra, S. K; Sangal, K; Kayshap, Pradeep; Guo, Yang; Pontin, David I; Uritsky, Vadim M; Ofman, Leon; Wang, Tongjiang; Yuan, Ding (American Astronomical Society, 2023-08-10)
    Multiwavelength observations of the propagating disturbances (PDs), discovered by Atmospheric Imaging Assembly (AIA) on board Solar Dynamics Observatory (SDO), are analyzed to determine their driving mechanism and physical ...
  • Reconstruction of Solar Features from an Image of Partially Eclipsed Sun 
    Krishnakumar, V; Venkatakrishnan, P (Indian Institute of Astrophysics, Bangalore, 1997)
    The photoheliograms obtained at Kodaikanal during the partial eclipse of the Sun on October 24, 1995 were digitised on a PDS microdensitometer. The lunar limb was used as a standard source for the digital reconstruction ...
  • Reconstruction of the past total solar irradiance on short timescales 
    Jain, K; Hasan, S. S (American Geophysical Union, 2004)
    The aim of this investigation is to present a new analysis of short-term variations in total solar irradiance by developing regression models and to extend these to epochs when irradiance measurements were not available. ...
  • Record of extended corona using colour video 
    Saxena, A. K; Samson, J. P. A; Lancelot, J. P (Indian Institute of Astrophysics, Bangalore, 1997)
    The entire event of the total solar eclipse of October 24 1995 was vediographed at our Kalpi camp. We have used SONY handy cam Video 8 Model No. CCD FX 280E PAL attached with 12x variable zoom lens. Partial eclipse was ...
