Identifying the nature and source of ultra‐low frequencies (ULF) waves (f⪅ 4 mHz) at
discrete frequencies in the Earth's magnetosphere is a complex task. The challenge comes …

Mesoscale density structures in the solar wind are often periodic, with f∼ 0.1–5 mHz. They
are trains of advected density structures with radial length scales of∼ 100–10,000 Mm …

Mesoscale periodic structures observed in solar wind plasma serve as an important
diagnostic tool for constraining the processes that govern the formation of the solar wind …

We present a new spectral analysis method for the identification of periodic signals in
geophysical time series. We evaluate the power spectral density with the adaptive multitaper …

Periodic density structures (PDSs) are quasiperiodic variations of solar wind density ranging
from a few minutes to a few hours. PDSs advect with the solar wind and have radial length …

Understanding the solar corona requires knowledge of its dynamics through its various
layers and subsequent connectivity to the heliosphere. This requires understanding the …

We revisit a quiet 14 day period of solar minimum during 2008 January and track
substreamer propagating disturbances (PDs) from low heights in STEREO/EUVI to the …

Mesoscale periodic density structures observed in the solar wind plasma serve as an
