Kinetic-scale current sheets in near-Sun solar wind: properties, scale-dependent features and reconnection onset
Autor: Lotekar, A., Vasko, I. Y., Phan, T., Bale, S. D., Bowen, T. A., Halekas, J., Artemyev, A. V., Khotyaintsev, Yu., Mozer, F. S.
We present statistical analysis of 11,200 proton kinetic-scale current sheets (CS) observed by Parker Solar Probe during 10 days around the first perihelion. The CS thickness $\lambda$ is in the range from a few to 200 km with the typical value aroun

Understanding Forbush decrease drivers based on shock-only and CME-only models using global signature of February 14, 1978 event
Autor: Raghav, Anil, Bhaskar, Ankush, Lotekar, Ajay, Vichare, Geeta, Yadav, Virendra
Publikováno v: Journal of Cosmology and Astroparticle Physics Volume 2014 October 2014
We have studied Forbush decrease (FD) event occurred on February 14, 1978 using 43 neutron monitor observatories to understand the global signature of FD. We have studied rigidity dependence of shock amplitude and total FD amplitude. We have found al

Statistical Study of Shock Rippling
Autor: Yuri Khotyaintsev, Ajay Lotekar, Andreas Johlander, Daniel Graham, Ahmad Lalti
MMS can resolve the fine structure of the shock ramp, which often shows holes in reduced ion-phase space distributions (integrated along the tangential plane of the shock). This is possible due to the high temporal resolutions of FPI/DIS. Such holes

Statistical study of the ripples and reformation in the collisionless shocks using MMS observation
Autor: Ajay Lotekar, Yuri Khotyaintsev, Daniel Graham, Andrew Dimmock, Ahmad Lalti, Andreas Johlander
Collisionless shocks are ubiquitous throughout the universe in near-Earth and astrophysical plasma environments. The behavior of collisionless shocks in terms of their structure and energy dissipation has been the subject of extensive research over m

Spacecraft Observations and Theoretical Understanding of Slow Electron Holes
Autor: F. S. Mozer, Sergey R. Kamaletdinov, Ajay Lotekar, Ivan Y. Vasko, Ian H. Hutchinson, Anton Artemyev
Publikováno v: Physical review letters. 127(16)
We present Magnetospheric Multiscale observations showing large numbers of slow electron holes with speeds clustered near the local minimum of double-humped velocity distribution functions of background ions. Theoretical computations show that slow e
