  • CCD photometry of the galactic open star clusters. I - King 10 
    Mohan, V; Pandey, A. K; Paliwal, D. C; Sagar, R; Mahra, H. S (Astronomical Society of India, 1992)
    CCD photometry of the open cluster King 10 has been carried out in the UBVRI photometric passbands down to V of about 19.5 mag. The reddening for the cluster region is found to be variable. A distance of 3.2 kpc has been ...
  • CCD Photometry of the Open Cluster BE 69 
    Pandey, A. K; Durgapal, A. K; Bhatt, B. C; Mohan, V; Mahra, H. S (International Astronomical Union, 1996)
    The morphological features of CMDs of Be 69 are better understood in terms of convective overshooting.The Comparison of CMDs with the convective overshoot models (Bertelli et al. 1994)produces a good fit for metallicity ...
  • Evolution of a Peculiar Type Ibn Supernova SN 2019wep 
    Gangopadhyay, A; Misra, Kuntal; Hosseinzadeh, Griffin; Arcavi, Iair; Pellegrino, Craig; Wang, Xiaofeng; Andrew Howell, D; Burke, Jamison; Zhang, Jujia; Kawabata, Koji; Singh, Mridweeka; Dastidar, Raya; Hiramatsu, Daichi; McCully, Curtis; Mo, Jun; Chen, Zhihao; Xiang, Danfeng (American Astronomical Society, 2022-05-10)
    We present a high-cadence short term photometric and spectroscopic monitoring campaign of a type Ibn SN 2019wep, which is one of the rare SN Ibn after SNe 2010al and 2019uo to display signatures of flash ionization (He ii, ...
  • Flash Ionization Signatures in the Type Ibn Supernova SN 2019uo 
    Gangopadhyay, A; Misra, K; Hiramatsu, D; Wang, Shan-Qin; Hosseinzadeh, G; Wang, Xiaofeng; Valenti, Stefano; Zhang, Jujia; Howel, D. A; Arcavi, Iair; Anupama, G.

K; Pankaj Sanwal; Singh, A; Singh, M; Zhang, Jicheng; Zhang, Tianmeng; Zhang, Xinhan (IOP Publishing, 2020-02-01)
    We present photometric and spectroscopic observations of the type Ibn supernova (SN) 2019uo, the second ever SN Ibn with flash ionization (He ii, C iii, N iii) features in its early spectra. SN 2019uo displays a rapid ...

T; Norbu, Rigzin; Sharma, Tarun Kumar; Stanzin, Jigmet; Stanzin, Tsewang; Stanzin, Urgain (American Astronomical Society, 2022-09-01)
    We present the design and performance of the GROWTH-India telescope, a 0.7 m robotic telescope dedicated to time-domain astronomy. The telescope is equipped with a 4k back-illuminated camera that gives a 0fdg82 field of ...
  • Photometric performance of UPSO CCD system 
    Mohan, V; Paliwal, D. C; Mahra, H. S (Astronomical Society of India, 1991)
    The photometrics CCD system obtained by the Uttar Pradesh State Observatory is discussed. The calibration of the system is described and its photometric performance is evaluated based on photometric transformation coefficients
  • UBV CCD standards in two galactic directions-II 
    Mohan, V; Sanwal, B. B; Paliwal, D. C; Pandey, A. K; Bhatt, B. C; Robin, A. C (Astronomical Society of India, 1996)
