  • Differential Rotation of the Solar Chromosphere: A Century-long Perspective from Kodaikanal Solar Observatory Ca II K Data 
    Mishra, Dibya Kirti; Routh, Srinjana; Jha, Bibhuti K; Chatzistergos, Theodosios; Basu, Judhajeet; Chatterjee, Subhamoy; Banerjee, D; Ermolli, Ilaria (American Astronomical Society, 2024-01-20)
    Chromospheric differential rotation is a key component in comprehending the atmospheric coupling between the chromosphere and the photosphere at different phases of the solar cycle. In this study, we therefore utilize the ...
  • Far-ultraviolet to Near-infrared Observations of SN 2023ixf: A High-energy Explosion Engulfed in Complex Circumstellar Material 
    Teja, Rishabh Singh; Singh, Avinash; Basu, Judhajeet; Anupama, G. C; Sahu, D. K; Dutta, Anirban; Swain, Vishwajeet; Nakaoka, Tatsuya; Pathak, Utkarsh; Bhalerao, Varun; Barway, Sudhanshu; Kumar, Harsh; Nayana, A. J; Imazawa, Ryo; Kumar, Brajesh; Kawabata, Koji S (American Astronomical Society, 2023-09-01)
    We present early-phase panchromatic photometric and spectroscopic coverage spanning the far-ultraviolet to near-infrared regime of the nearest hydrogen-rich core-collapse supernova (SN) in the last 25 yr, SN 2023ixf. We ...

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 ...
  • Multiwavelength Observations of Multiple Eruptions of the Recurrent Nova M31N 2008-12a 
    Basu, Judhajeet; Pavana, M; Anupama, G. C; Barway, Sudhanshu; Singh, Kulinder Pal; Swain, Vishwajeet; Srivastav, Shubham; Kumar, Harsh; Bhalerao, Varun; Sonith, L. S; Selvakumar, G (American Astronomical Society, 2024-05-01)
    We report the optical, UV, and soft X-ray observations of the 2017–2022 eruptions of the recurrent nova M31N 2008-12a. We find a cusp feature in the r¢- and i¢-band light curves close to the peak, which could be related ...
