Propagating waves in polar coronal holes as seen by SUMER and EIS
D. Banerjee, L. Teriaca, G. R. Gupta +3
To study the dynamics of coronal holes and the role of waves in the acceleration of the solar wind, spectral observations were performed over polar coronal hole regions with the SU…
On the statistical detection of propagating waves in polar coronal holes
G. R. Gupta, E. O'Shea, D. Banerjee +2
Waves are important for the heating of the solar corona and the acceleration of the solar wind. We have examined a long spectral time series of a northern coronal hole observed on…
Near Infrared Observations of the novae V2491 Cygni and V597 Puppis
Sachindra Naik, D. P. K. Banerjee, N. M. Ashok
We present results obtained from near-infrared JHK spectroscopic observations of novae V2491 Cyg and V597 Pup in the early declining phases of their 2007 and 2008 outbursts respect…
Near-Infrared Studies of V1280 Sco (Nova Scorpii 2007)
Ramkrishna Das, Dipankar Banerjee, Nagarhalli Ashok +1
We present spectroscopic and photometric results of Nova V1280 Sco which was discovered in outburst in early 2007 February. The large number of spectra obtained of the object leads…
VLTI monitoring of the dust formation event of the Nova V1280 Sco
Olivier Chesneau, Dipankar Banerjee, F. Millour +13
We present the first high spatial resolution monitoring of the dust forming nova V1280 Sco performed with the Very Large Telescope Interferometer (VLTI). Spectra and visibilities w…
A near-infrared shock wave in the 2006 outburst of recurrent nova RS Ophiuchi
Ramkrishna Das, Dipankar P. K. Banerjee, Nagarhalli M. Ashok
Near-infrared spectra are presented for the recent 2006 outburst of the recurrent nova RS Ophiuchi (RS Oph).We report the rare detection of an infrared shock wave as the nova eject…
