Modeling star-planet interactions in far-out planetary and exoplanetary systems
Srijan Bharati Das, Arnab Basak, Dibyendu Nandy +1
The outflowing magnetized wind from a host star shapes planetary and exoplanetary magnetospheres dictating the extent of its impact. We carry out three-dimensional (3D) compressibl…
Stellar mid-life crisis: subcritical magnetic dynamos of solar-like stars and the breakdown of gyrochronology
Bindesh Tripathi, Dibyendu Nandy, Soumitro Banerjee
Recent observations reveal the surprising breakdown of stellar gyrochronology relations at about the Sun's age hinting that middle-aged, solar-like stars transition to a magnetical…
The Association of Filaments, Polarity Inversion Lines, and Coronal Hole Properties with the Sunspot Cycle: An Analysis of the McIntosh Database
Rakesh Mazumder, Prantika Bhowmik, Dibyendu Nandy
Filaments and coronal holes, two principal features observed in the solar corona are sources of space weather variations. Filament formation is closely associated with polarity inv…
Dependence of coronal mass ejection properties on their solar source active region characteristics and associated flare reconnection flux
Sanchita Pal, Dibyendu Nandy, Nandita Srivastava +2
The near-Sun kinematics of coronal mass ejections (CMEs) determine the severity and arrival time of associated geomagnetic storms. We investigate the relationship between the depro…
The Extended Solar Cycle: Muddying the Waters of Solar/Stellar Dynamo Modeling Or Providing Crucial Observational Constraints?
A. K. Srivastava, S. W. McIntosh, N. Arge +17
In 1844 Schwabe discovered that the number of sunspots increased and decreased over a period of about 11 years, that variation became known as the sunspot cycle. Almost eighty year…
Asymmetry in Solar Torsional Oscillation and the Sunspot Cycle
Lekshmi B, Dibyendu Nandy, H M Antia
Solar torsional oscillations are migrating bands of slower- and faster-than-average rotation, which are strongly related to the Sun's magnetic cycle. We perform a long-term study (…
