  • 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 ...
  • Post-outburst Evolution of Bona Fide FU Ori-type V2493 Cygnus: A Spectro-photometric Monitoring 
    Ghosh, Arpan; Sharma, Saurabh; Ninan, Joe P; Ojha, Devendra K; Bhatt, B. C; Sahu, D. K; Baug, Tapas; Yadav, R. K; Irawati, Puji; Gour, A. S; Panwar, Neelam; Pandey, Rakesh; Sinha, Tirthendu; Verma, Aayushi (American Astronomical Society, 2023-09-01)
    We present here the results of 8 yr of our near-simultaneous optical–near-infrared spectro-photometric monitoring of the bona fide FU Ori (FUor)-type candidate V2493 Cygnus (V2493 Cyg) starting from 2013 September to 2021 ...
  • Probing Transit Timing Variation and Its Possible Origin with 12 New Transits of TrES-3b 
    Mannaday, V. K; Thakur, P; Jiang, I; Sahu, D. K; Joshi, Y. C; Pandey, A. K; Joshi, S; Yadav, R. K; Su, Li-Hsin; Sariya, D. P; Yeh, Li-Chin; Griv, Evgeny; Mkrtichian, D; Shlyapnikov, A; Moskvin, V; Ignatov, V; Vanko, M; Puskullu, C (IOP Publishing, 2020-07)
    We present 12 new transit light curves of the hot-Jupiter TrES-3b observed during 2012−2018 to probe the transit timing variation (TTV). By combining the midtransit times determined from these 12 transit data with ...
