Magnetic interaction of stellar coronal mass ejections with close-in exoplanets: implication on planetary mass loss and Ly- transits
Gopal Hazra, Aline A. Vidotto, Stephen Carolan +2
Coronal Mass Ejections (CMEs) erupting from the host star are expected to have effects on the atmospheric erosion processes of the orbiting planets. For planets with a magnetospher…
Mean field models of flux transport dynamo and meridional circulation in the Sun and stars
Gopal Hazra, Dibyendu Nandy, Leonid Kitchatinov +1
The most widely accepted model of the solar cycle is the flux transport dynamo model. This model evolved out of the traditional dynamo model which was first developed at a tim…
Recent advances in the 3D kinematic Babcock-Leighton solar dynamo modeling
Gopal Hazra
In this review, we explain recent progress made in the Babcock-Leighton dynamo models for the Sun, which have been most successful to explain various properties of the solar cycle.…
Influence of the Sun-like magnetic cycle on exoplanetary atmospheric escape
Gopal Hazra, Aline A. Vidotto, Carolina Villarreal D'Angelo
Stellar high-energy radiation (X-ray and extreme ultraviolet, XUV) drives atmospheric escape in close-in exoplanets. Given that stellar irradiation depends on the stellar magnetism…
Exploring cycle period and parity of stellar magnetic activity with dynamo modeling
Gopal Hazra, Jie Jiang, Bidya Binay Karak +1
Observations of chromospheric and coronal emissions from various solar-type stars show that the stellar magnetic activity varies with the rotation rates of the stars. The faster th…
A New Formula for Predicting Solar Cycles
Gopal Hazra, Arnab Rai Choudhuri
A new formula for predicting solar cycles based on the current theoretical understanding of the solar cycle from flux transport dynamo is presented. Two important processes---fluct…
