Near-infrared Observations of Be/X-ray Binary Pulsar A0535+262
Sachindra Naik, Blesson Mathew, D. P. K. Banerjee +2
We present results obtained from an extensive near-infrared spectroscopic and photometric observations of the Be/X-ray binary A0535+262/HDE 245770 at different phases of its ~111 d…
The 2011 outburst of the recurrent novaT Pyx. Evidence for a face-on bipolar ejection
Olivier Chesneau, A. Meilland, D. P. K. Banerjee +19
We report on near-IR interferometric observations of the outburst of the recurrent nova T Pyx. We obtained near-IR observations of T Pyx at dates ranging from t=2.37d to t=48.2d af…
Analysis of the coronal green line profiles: evidence of excess blueshifts
K. P. Raju, T. Chandrasekhar, N. M. Ashok
The coronal green line (Fe XIV 5303 A) profiles were obtained from Fabry-Perot interferometric observations of the solar corona during the total solar eclipse of 21 June 2001 from…
Nova V5579 Sgr 2008: near-infrared studies during maximum and the early decline phase
Ashish Raj, N. M. Ashok, D. P. K. Banerjee
We present near-infrared spectroscopic and photometric observations of the nova V5579 Sgr during the maximum and early decline phase. The spectra follow the evolution of the nova f…
A study of the near-infrared modulation at spin and orbital periods in the intermediate polar WX Pyx
V. H. Joshi, N. M. Ashok, D. P. K. Banerjee
We present near-infrared band photometric observations of the intermediate polar WX Pyx. The frequency analysis indicates the presence of a period at 1559.2 0.2 seconds w…
