    The Gaia Alert System issued an alert on 2020 August 28, on Gaia 20eae when its light curve showed a ∼4.25 magnitude outburst. We present multiwavelength photometric and spectroscopic follow-up observations of this source ...
  • Photometric variable stars in the young open cluster NGC 6823 
    Lata, Sneh; Chen, W. P; Pandey, J. C; Dileep, Athul; Ai, Zhong-Han; Hojaev, Alisher S; Panwar, Neelam; Joshi, Santosh; Mondal, Soumen; Biswas, Siddhartha; Bhatt, B. C (Oxford University Press on behalf of Royal Astronomical Society, 2023-03)
    We present stellar variability towards the young open cluster NGC 6823. Time series V- and I-band CCD photometry led to identification and characterization of 88 variable stars, of which only 14 have been previously ...
  • Post-outburst Evolution of Bona Fide FU Ori-type V2493 Cygnus: A Spectro-photometric Monitoring
