Infrared spectroscopy of the recent outburst in V1047 Cen (Nova Centauri 2005)
T. R. Geballe, D. P. K. Banerjee, A. Evans +14
Fourteen years after its eruption as a classical nova (CN), V1047 Cen (Nova Cen 2005) began an unusual re-brightening in 2019 April. The amplitude of the brightening suggests that…
Simultaneous longitudinal and transverse oscillations in filament threads after a failed eruption
Rakesh Mazumder, Vaibhav Pant, Manuel Luna +1
Longitudinal and transverse oscillations are frequently observed in the solar prominences and/or filaments. These oscillations are excited by a large scale shock wave, impulsive fl…
Delving into the Historical Ca II K Archive from the Kodaikanal Observatory: the Potential of the Most Recent Digitised Series
Theodosios Chatzistergos, Ilaria Ermolli, Sami K. Solanki +4
Full-disc Ca II K photographic observations of the Sun carry direct information about the evolution of solar-plage regions for more than a century and are therefore a unique datase…
The 2018 eruption and long term evolution of the new high-mass Herbig Ae/Be object Gaia-18azl = VES 263
U. Munari, V. Joshi, D. P. K. Banerjee +9
We have been monitoring, at high cadence, the photometric and spectroscopic evolution of VES 263 following the discovery in 2018 of a brightening labeled as event Gaia-18azl. VES 2…
Study of Sunspot Penumbra to Umbra Area Ratio using Kodaikanal White-light Digitized Data
Bibhuti Kumar Jha, Sudip Mandal, Dipankar Banerjee
We study the long-term behaviour of sunspot penumbra to umbra area ratio by analyzing the recently digitized Kodaikanal white-light data (1923-2011). We implement an automatic umbr…
High-frequency dynamics of active region moss as observed by IRIS
Nancy Narang, Vaibhav Pant, Dipankar Banerjee +1
The high temporal, spatial and spectral resolution of Interface Region Imaging Spectrograph (IRIS) has provided new insights into the understanding of different small-scale process…
