  • Broad-band polarimetric investigation of the Type II-plateau supernova 2013ej 
    Brajesh Kumar; Pandey, S. B; Eswaraiah, C; Kawabata, K. S (Oxford University Press on behalf of the Royal Astronomical Society, 2016-03)
    We present results based on follow-up observations of the Type II-plateau supernova (II-P SN) 2013ej at six epochs spanning a total duration of ∼ 37 d. The R C -band linear polarimetric observations were carried out ...
  • Deep optical survey of the stellar content of Sh2-311 region 
    Yadav, Ram Kesh; Pandey, A. K; Sharma, Saurabh; Jose, J; Ogura, K; Kobayashi, N; Samal, M. R; Eswaraiah, C; Chandola, H. C (Elsevier, 2015-01)
    The stellar content in and around Sh2-311 region have been studied using the deep optical observations as well as near-infrared (NIR) data from 2MASS. The region contains three clusters, viz. NGC 2467, Haffner 18 and Haffner ...
  • On the observational behaviour of the highly polarized Type IIn supernova SN 2017hcc 
    Brajesh Kumar; Eswaraiah, C; Singh, A; Sahu, D. K; Anupama, G. C; Kawabata, K. S; Yamanaka, Masayuki; Otsubo, Ikki; Pandey, S. B; Nakaoka, Tatsuya; Kawabata, Miho; Aryan, Amar; Akitaya, Hiroshi (Oxford University Press on behalf of the Royal Astronomical Society, 2019-09)
    We present the results based on photometric (Swift UVOT), broad-band polarimetric (V and Rbands) and optical spectroscopic observations of the Type IIn supernova (SN) 2017hcc. Our study is supplemented with spectropolarimetric ...
  • Optical and near-infrared survey of the stellar contents associated with the star-forming complex Sh2-252 
    Jose, J; Pandey, A. K; Ogura, K; Samal, M. R; Ojha, D. K; Bhatt, B. C; Chauhan, N; Eswaraiah, C; Mito, H; Kobayashi, N; Yadav, R. K (Wiley-Blackwell, 2012-08)
    We present the analyses of the stellar contents associated with the extended H ii region Sh2-252 using deep optical UBVRI photometry, slit and slitless spectroscopy along with the near-infrared (NIR) data from Two-Micron ...
  • Optical Photometric and Polari metric investigation of NGC 1931 
    Pandey, A. K; Eswaraiah, C; Sharma, S; Samal, M. R; Chauhan, N; Chen, W. P; Jose, J; Ojha, D. K; Yadav, Ram Kesh; Chandola, H. C (IOP Publishing, 2013-02-05)
    We present optical photometric and polarimetric observations of stars toward NGC 1931 with the aim of deriving cluster parameters such as distance, reddening, age, and luminosity/mass function as well as understanding dust ...
  • Polarimetric and photometric investigation of the dark globule LDN 1225: distance, extinction law, and magnetic fields 
    Eswaraiah, C; Lai, Shih-Ping; Ma, Yuehui; Anil K. Pandey; Jose, J; Chen, Zhiwei; Samal, M. R; Wang, Jia-Wei; Sharma, S; Ojha, D. K (IOP Publishing, 2019-04-10)
    We present results based on the optical R-band observations of the polarization of 280 stars distributed toward the dark globule LDN 1225. Parallaxes from Gaia data release 2 along with the polarization data of ~200 stars ...
  • A study of 2175 Å absorption feature with TAUVEX: An Indo-Israeli UV mission 
    Muthumariappan, C; Maheswar, G; Eswaraiah, C; Pandey, A. K (International Astronomical Union, 2008-02)
    TAUVEX is an Indo-Israeli collaborative mission to make photometric observations in the UV region. Using the narrowband filters positioned near 2175 Å feature, we plan to construct the UV bump in the extinction curve towards ...
  • A study of the starless dark cloud LDN 1570: Distance, dust properties, and magnetic field geometry 
    Eswaraiah, C; Maheswar, G; Pandey, A. K; Jose, J; Ramaprakash, A. N; Bhatt, H. C (EDP Sciences, 2013-08)
    Aims. We aim to map the magnetic field geometry and to study the dust properties of the starless cloud, L1570, using multi-wavelength optical polarimetry and photometry of the stars projected on the cloud. Methods. The ...
  • Young stellar population and ongoing star formation in the H ii complex Sh2-252 
    Jose, J; Pandey, A. K; Samal, M. R; Ojha, D. K; Ogura, K; Kim, J. S; Kobayashi, N; Goyal, A; Chauhan, N; Eswaraiah, C (Oxford University Press on behalf of the Royal Astronomical Society, 2013-07-11)
    In this paper, an extensive survey of the star-forming complex Sh2-252 has been undertaken with an aim to explore its hidden young stellar population as well as to understand the structure and star formation history for ...
