Helical Magnetic Fields in Solar Active Regions: Theory vs. Observations
K. Petrovay, P. Chaterjee, A. Choudhuri
The mean value of the normalized current helicity in solar active regions is on the order of 1e-8 1/m, negative in the northern hemisphere, positive in the southern hemisphere. Obs…
Predicting solar cycle 24 with a solar dynamo model
Arnab Rai Choudhuri, Piyali Chatterjee, Jie Jiang
Whether the upcoming cycle 24 of solar activity will be strong or not is being hotly debated. The solar cycle is produced by a complex dynamo mechanism. We model the last few solar…
Why do millisecond pulsars have weaker magnetic fields compared to ordinary pulsars?
Arnab Rai Choudhuri, Sushan Konar
Millisecond pulsars, with magnetic fields weaker by three to four orders compared to those of ordinary pulsars, are presumed to be neutron stars spun up by binary accretion. We exp…
On Solar Radius Variation with Magnetic Field
Arnab Rai Choudhuri, Piyali Chatterjee
In response to the claim by Dziembowski et al. (2001) that the solar radius decreases with magnetic activity at the rate of 1.5 km/yr, we consider the theoretical question whether…
Diamagnetic Screening of the Magnetic Field in Accreting Neutron Stars
Sushan Konar, Arnab Rai Choudhuri
A possible mechanism for screening of the surface magnetic field of an accreting neutron star, by the accreted material, is investigated. In particular, we investigate the nature o…
