Rotation suppresses giant-scale solar convection
Proceedings of the National Academy of Sciences of the United States of America, 2021 Significance The entire Sun completes a full rotation in roughly 28 d. Within the outer 30% of the solar interior, turbulent thermal convection powers fluid outward.

Helioseismic evidence that the solar dynamo originates near the tachocline [PDF]
Scientific ReportsThe exact location of the solar dynamo remains uncertain–whether it operates primarily in the near-surface shear layer, throughout the entire convection zone, or near the tachocline - a region of sharp transition in the solar rotation, located at the ...

A long-term multifrequency study of solar rotation using the solar radio flux and its relationship with solar cycles [PDF]
Monthly notices of the Royal Astronomical Society, 2021 This paper examines long-term (more than four solar cycles) temporal and spatial fluctuations in the solar rotation by investigating radio-emission escapes from various layers of the solar atmosphere during the years 1967–2010.

Generation of Solar-like Differential Rotation [PDF]
Astrophysical Journal, 2022 We analyze the simulation result shown in Hotta & Kusano (2021) in which the solar-like differential rotation is reproduced. The Sun is rotating differentially with the fast equator and the slow pole.

Inference of Solar Rotation from Perturbations of Acoustic Mode Eigenfunctions [PDF]
Astrophysical Journal, 2020 Today’s picture of the internal solar rotation rate profile results essentially from helioseismic analyses of frequency splittings of resonant acoustic waves. Here we present another, complementary estimation of the internal solar rotation rate using the

Journal of Geophysical Research: Space Physics, 2021 The delayed ionospheric response is analyzed for two well‐defined 27‐day solar rotation periods in the year 2019 with solar radio flux index F10.7 and Global‐scale Observations of the Limb and Disk (GOLD) data, like solar extreme ultraviolet (EUV) flux ...

Solar differential rotation reproduced with high-resolution simulation [PDF]
Nature Astronomy, 2021 The Sun rotates differentially with a fast equator and slow pole1. Convection in the solar interior is thought to maintain the differential rotation. However, although many numerical simulations have been conducted to reproduce the solar differential ...

Radial gradient of the solar rotation rate in the near-surface shear layer of the Sun
Frontiers in Astronomy and Space Sciences, 2022 We study the radial gradient of the solar rotation rate in the near-surface shear layer (NSSL) from about .950 R⊙ to the solar surface and its variation during Solar Cycles 23 and 24 with ring-diagram analysis applied to Global Oscillation Network Group (

Measurements of Solar Differential Rotation Using the Century Long Kodaikanal Sunspot Data [PDF]
, 2021 The rotational profile of the Sun is considered to be one of the key inputs in a solar dynamo model. Hence, precise and long-term measurements of this quantity is important for our understanding of solar magnetism and its variability.

Changes in Solar Rotation over Two Solar Cycles [PDF]
Astrophysical Journal, 2019 We use helioseismic data from ground- and space-based instruments to analyze how solar rotation has changed since the beginning of solar Cycle 23 with emphasis on studying the differences between Cycles 23 and 24.
