  • Photometric variability of blue straggler stars in M67 with TESS and K2 
    Vernekar, Nagaraj; Subramaniam, A; Jadhav, Vikrant V; Bowman, Dominic M (Oxford University Press on behalf of Royal Astronomical Society, 2023-09)
    Blue straggler stars (BSSs) are formed through mass transfers or mergers in binaries. The recent detections of white dwarf (WD) companions to BSSs in M67 suggested a mass transfer pathway of formation. In search of a close ...

    Optical, near-infrared (NIR) photometric and spectroscopic studies, along with the optical imaging polarimetric results for SN 2012au, are presented in this article to constrain the nature of the progenitor and other ...
  • Photometric, spectroscopic and polarimetric variability of the weak-emission T Tauri star HD 288313 
    Mekkaden, M. V; Muneer, S; Raveendran, A. V (Blackwell Publishing, 2007-07)
    Photometric observations over three seasons show HD 288313 to be a light variable with a 2.2636-d period. The observed V amplitudes lie in the range of 0.06–0.15 mag. The star showed appreciable changes in the brightness ...
  • A photometric-dynamic model to simulate coma and jets from a comet. Application to comet Hale-Bopp (C/1995 O1) 
    Vasundhara, R (EDP Sciences, 2002-01)
    A model to compute the trajectories of dust grains ejected by comets to simulate intensity and polarization maps on the sky plane is presented. The model is used to constrain the silicate to organic mass ratio, porosity ...
  • Photometry and low resolution spectroscopy of hot post-AGB candidates 
    Gauba, G; Parthasarathy, M; Kumar, B; Yadav, R. K. S; Sagar, R (The European Southern Observatory, 2003-06)
    We have obtained Johnson U, B, V and Cousins R, I photometry and low resolution spectra of a small sample of hot post-AGB candidates. Using the present data in combination with JHK data from 2MASS, infrared data from the ...
  • Photometry and spectroscopy of II Peg, IM Peg and UX Ari 
    Dar, A. A; Parihar, P. S; Malik, M. A (IOP Publishing, 2018-08)
    V band photometry of three RS CVn stars, II Peg, IM Peg and UX Ari, is carried out to study the physical properties of these variables. We verified the significant and regular optical photometric variability to be present ...
