Asteroseismology of sz lyn using multi-band high time resolution photometry from ground and space
J. Adassuriya, S. Ganesh, J. L. Gutierrez +4
We report the analysis of high temporal resolution ground and space based photometric observations of SZ Lyncis, a binary star one of whose components is a high amplitude Scuti…
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…
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-…
Detection and characterisation of two VLM binaries: LP 1033-31 and LP 877-72
Subhajeet Karmakar, A. S. Rajpurohit, F. Allard +1
Using the high-resolution near-infrared adaptive optics imaging from the NaCo instrument at the Very Large Telescope, we report the discovery of a new binary companion to the M-dwa…
Magnetic and Velocity Field Topology in Active Regions of Descending Phase of the Solar Cycle 23
R. A. Maurya, A. Ambastha
We analyse the topology of photospheric magnetic fields and sub-photospheric flows of several active regions (ARs) that are observed during the peak to descending phase of the sola…
Development of a Confined Circular-cum-parallel Ribbon Flare and Associated Pre-flare Activity
Pooja Devi, Bhuwan Joshi, Ramesh Chandra +3
We study a complex GOES M1.1 circular ribbon flare and related pre-flare activity on 26 January 2015 [SOL26-01-2015] in solar active region NOAA 12268. This flare activity was obse…
