First analysis of in-situ observation of surface Alfvén waves in ICME flux rope
Anil Raghav, Omkar Dhamane, Zubair Shaikh +8
Alfvén waves (AWs) are inevitable in space and astrophysical plasma. Their crucial role in various physical processes, occurring in plasma, has triggered intense research in solar-…
Observation of Alfven wave in ICME-HSS interaction region
Omkar Dhamane, Anil Raghav, Zubair Shaikh +7
The Alfvén wave (AW) is the most common fluctuation present within the emitted solar wind from the Sun. Moreover, the interaction between interplanetary coronal mass ejection (ICME…
Changes in the near-surface shear layer of the Sun
H. M. Antia, Sarbani Basu
We use helioseismic data obtained over two solar cycles to determine whether there are changes in the near-surface shear layer (NSSL). We examine this by determining the radial gra…
Convective Differential Rotation in Stars and Planets II: Observational and Numerical Tests
Adam S. Jermyn, Shashikumar M. Chitre, Pierre Lesaffre +1
Differential rotation is central to a great many mysteries in stars and planets. In Part I we predicted the order of magnitude and scaling of the differential rotation in both hydr…
Convective Differential Rotation in Stars and Planets I: Theory
Adam S. Jermyn, Shashikumar M. Chitre, Pierre Lesaffre +1
We derive the scaling of differential rotation in both slowly- and rapidly-rotating convection zones using order of magnitude methods. Our calculations apply across stars and fluid…
Enhanced Rotational Mixing in the Radiative Zones of Massive Stars
Adam S. Jermyn, Christopher A. Tout, Shashikumar M. Chitre
Convection in the cores of massive stars becomes anisotropic when they rotate. This anisotropy leads to a misalignment of the thermal gradient and the thermal flux, which in turn r…
