Infrared spectroscopy of CK Vulpeculae: revealing a remarkably powerful blast from the past

D. P. K. Banerjee, T. R. Geballe, A. Evans +6

CK Vulpeculae, which erupted in AD 1670-71, was long considered to be a nova outburst; however, recent observations have required that alternative scenarios be considered. Long sli…

Automated Detection of Accelerating Solar Eruptions using Parabolic Hough Transform

Ritesh Patel, Vaibhav Pant, Priyanka Iyer +3

Solar eruptions such as Coronal Mass Ejections (CMEs) observed in the inner solar corona (up to 4 R) show acceleration profiles which appear as parabolic ridges in height…

Statistical Study of Plasmoids associated with post-CME Current Sheet

Ritesh Patel, Vaibhav Pant, K. Chandrashekhar +1

We investigate the properties of plasmoids observed in the current sheet formed after an X-8.3 flare followed by a fast CME eruption on September 10, 2017 using Extreme Ultraviolet…

Long-Term Evolution of the Sun's magnetic field during Cycles 15--19 based on their proxies from Kodaikanal Solar Observatory

Alexander V. Mordvinov, Bidya Binay Karak, Dipankar Banerjee +3

The regular observation of the solar magnetic field is available only for about last five cycles. Thus, to understand the origin of the variation of the solar magnetic field, it is…

UV spectroscopy confirms SU Lyn to be a symbiotic star

Vipin Kumar, Mudit K. Srivastava, Dipankar P. K. Banerjee +1

SU Lyn, a star that ostensibly appears to be an unremarkable late M type giant, has recently been proposed to be a symbiotic star largely based on its hard X-ray properties. The st…

Isotopic ratios in the red giant component of the recurrent nova T Coronae Borealis

Ya. V. Pavlenko, A. Evans, D. P. K. Banerjee +5

We report the determination of abundances and isotopic ratios for C, O and Si in the photosphere of the red giant component of the recurrent nova T Coronae Borealis from new 2.284-…
