Rossby waves in astrophysics

TV Zaqarashvili, M Albekioni, JL Ballester, Y Bekki… - Space Science …, 2021 - Springer
Rossby waves are a pervasive feature of the large-scale motions of the Earth's atmosphere
and oceans. These waves (also known as planetary waves and r-modes) also play an …

Period spacings of γ Doradus pulsators in the Kepler field: Rossby and gravity modes in 82 stars

G Li, T Van Reeth, TR Bedding… - Monthly Notices of the …, 2019 - academic.oup.com
Rossby modes are the oscillations in a rotating fluid, whose restoring force is the Coriolis
force. They provide an additional diagnostic to understand the rotation of stars, which …

The origin of the “seasons” in space weather

M Dikpati, PS Cally, SW McIntosh, E Heifetz - Scientific reports, 2017 - nature.com
Powerful 'space weather'events caused by solar activity pose serious risks to human health,
safety, economic activity and national security. Spikes in deaths due to heart attacks, strokes …

The detection of Rossby-like waves on the Sun

SW McIntosh, WJ Cramer, M Pichardo Marcano… - Nature …, 2017 - nature.com
Rossby waves are a type of global-scale wave that develops in planetary atmospheres,
driven by the planet's rotation. They propagate westward owing to the Coriolis force, and …

Tidally forced planetary waves in the tachocline of solar-like stars

GM Horstmann, G Mamatsashvili… - The Astrophysical …, 2023 - iopscience.iop.org
Can atmospheric waves in planet-hosting solar-like stars substantially resonate to tidal
forcing, perhaps at a level of impacting the space weather or even being dynamo-relevant …

Space weather challenge and forecasting implications of Rossby waves

M Dikpati, SW McIntosh - Space Weather, 2020 - Wiley Online Library
Rossby waves arise in thin layers within fluid regions of stars and planets. These global
wave‐like patterns occur due to the variation in Coriolis forces with latitude. In the past …

Equatorial magnetohydrodynamic shallow water waves in the solar tachocline

T Zaqarashvili - The Astrophysical Journal, 2018 - iopscience.iop.org
The influence of a toroidal magnetic field on the dynamics of shallow water waves in the
solar tachocline is studied. A sub-adiabatic temperature gradient in the upper overshoot …

A spectral solver for solar inertial waves

J Bhattacharya, SM Hanasoge - The Astrophysical Journal …, 2023 - iopscience.iop.org
Inertial waves, which are predominantly driven by the Coriolis force, likely play an important
role in solar dynamics, and, additionally, they provide a window into the solar subsurface …

On the connection between Rieger-type and magneto-Rossby waves driving the frequency of the large solar eruptions during solar cycles 19–25

MB Korsós, M Dikpati, R Erdélyi, J Liu… - The Astrophysical …, 2023 - iopscience.iop.org
Global solar activity variation mainly occurs over about an 11 yr cycle. However, both longer
and shorter periodicities than the solar cycle are also present in many different solar activity …

Role of interaction between magnetic Rossby waves and tachocline differential rotation in producing solar seasons

M Dikpati, SW McIntosh, G Bothun… - The Astrophysical …, 2018 - iopscience.iop.org
We present a nonlinear magnetohydrodynamic shallow-water model for the solar tachocline
(MHD-SWT) that generates quasi-periodic tachocline nonlinear oscillations (TNOs) that can …
