Decoding the X-Ray Flare from MAXI J0709–159 Using Optical Spectroscopy and Multiepoch Photometry

Bhattacharyya, Suman; Mathew, Blesson; Ezhikode, Savithri H; Muneer, S; Selvakumar, G; Maheswar, G; Arun, R; Anilkumar, Hema; Banerjee, Gourav; Kumar, S. P; Kartha, Sreeja S; Paul, KT; Velu, C (IOP Publishing, 2022-07-10)

We present a follow-up study on the recent detection of two X-ray flaring events by MAXI/Gas Slit Camera observations in soft and hard X-rays from MAXI J0709–159 in the direction of HD 54786 (LY CMa), on 2022 January 25. ...
Excitation Mechanism of O i Lines in Herbig Ae/Be Stars

Mathew, v; Manoj, P; Narang, Mayank; Banerjee, D. P. K; Pratheeksha Nayak; Muneer, S; Vig, S; Kumar, S. P; Paul, K. T; Maheswar, G (IOP Publishing, 2018-04-10)

We have investigated the role of a few prominent excitation mechanisms viz. collisional excitation, recombination, continuum fluorescence, and Lyman beta fluorescence on the O i line spectra in Herbig Ae/Be stars. The aim ...
Photon polarization in np fusion

Ramachandran, G; Deepak, P. N; Kumar, S. P (Institute of Physics Publishing Ltd., 2003-06)

A model-independent irreducible tensor formalism is developed to discuss photon polarization in np fusion. It is shown that photon polarization arising out of the interference of the dominant isovector M1 amplitude at ...
