Evidence for dynamical changes in Betelgeuse using multi-wavelength data
Sneha Kachhara, Sandip V. George, Ranjeev Misra +1
The reasons behind the Great Dimming and subsequent rising in the brightness of Betelgeuse between October 2019 and March 2020 still continue to baffle astronomers. It has been sho…
Early Warning Signals Indicate a Critical Transition in Betelgeuse
Sandip V. George, Sneha Kachhara, Ranjeev Misra +1
Critical transitions occur in complex dynamical systems, when the system dynamics undergoes a regime shift. These can often occur with little change in the mean amplitude of system…
Classification of Close Binary Stars Using Recurrence Networks
Sandip V. George, R. Misra, G. Ambika
Close binary stars are binary stars where the component stars are close enough such that they can exchange mass and/or energy. They are subdivided into semi-detached, overcontact o…
